Replacement rechargeable battery for iPod Mini 2nd Generation. Use it for poor runtime, swelling, or power loss after cable and power-source checks, while remembering that bad storage or board faults can imitate battery trouble.
Product Overview
This battery listing covers Replacement Battery and its own connector path on the iPod Mini 2nd Generation.
Use Part Details for the confirmed part-number reference. Use the Compatible Variants table below to confirm capacity, color, or order-number fitment.
Choose this part when your iPod shows Won't Charge, Won't Turn On, Shuts Down Randomly, or Battery Drain; the checks below help confirm the right part before you order.
If a known-good battery, cable, and power source still do not restore stable power, the problem might be the dock connector, battery connector, or something on the board, not just the battery.
What Is Included
Condition: New replacement part. Quantity and exclusions: The listed part, set, pair, or configuration above is supplied with exactly one plastic pry tool. No other parts, tools, adhesives, or materials are included unless they are explicitly listed above.
Quick Buying Check
Buy this when
- Won't Charge: Verify the charger, cable, dock connector, and storage spin-up load first; use the battery check when runtime, no-charge, shutdown, or swelling behavior still follows the pack.
Diagnose first when
- Confirm the capacity match before ordering: 4GB, 6GB.
- Test with a known-good charger and cable before opening the iPod.
- Force restart the iPod and inspect the battery connector if the symptom started after service.

Diagnostic Failure Cards
Use these model-specific failure cards to decide whether this battery is the right part, a nearby part needs checking first, or escalation makes more sense after simpler checks.
| Symptom | What it means & what to check |
|---|---|
| Symptom remains after basic checks |
What you may see: The iPod still points back to Replacement Battery after cable seating, battery stability, and nearby connector checks. Check first: Retest with known-good cables or adjacent parts where practical before ordering. Check next: A nearby cable, connector, battery, storage device, display path, audio path, or board path can mimic a bad battery. |
| Symptom changes when touched or reseated |
What you may see: The symptom changes after moving the part, reseating a cable, or applying light pressure near the connector path. Check first: Inspect the connector, latch, flex, solder joints, and nearby board area for damage or corrosion. Check next: This can still be a connection issue rather than a failed battery alone. |
| Problem began after another repair |
What you may see: The issue started immediately after opening the iPod, replacing another part, or disturbing an internal cable. Check first: Reopen only as far as needed and inspect the exact area touched during the previous repair. Check next: Post-repair symptoms often trace to seating, latch, screw, or cable issues before Replacement Battery itself is confirmed bad. |

Repair considerations
Run these checks before replacing the battery — they confirm the battery is the right fix and not a nearby fault:
- Try known-good cable, charger, USB port, or computer
- Replace battery
Do Not Buy / Problems This Battery Does Not Fix
| Situation | Start here instead |
|---|---|
| Charging, swelling, runtime, or power is the primary problem | Start with battery health, charger and cable behavior, and power-load checks for your model before buying this part. |
| You see a folder icon, clicking noise, or restore failure | Check the drive or flash media, storage cable, adapter seating, formatting, and restore path before replacing any part. |
| Only the screen is affected and everything else works | Start with the screen, display ribbon and backlight path — and do inspect the pack, because on this model it lies behind the display, so a swollen cell marks or lifts the panel while everything else still works. |
| A symptom points to a different part | Start with hard-drive cable for folder, clicking, or restore symptoms; dock-port bracket when the dock area itself is loose or shifted — bent or corroded pins are on the 30-pin port, which is part of the logic board on this model, and the bracket only locates it; click wheel for click-wheel or control symptoms; logic board for board-side damage or multi-system symptoms before buying this part. |
| Recent service or connector disturbance is the main clue | Inspect and reseat the cable, latch, or connector path disturbed during service before buying another part. |
| Variant or capacity does not match this listing | Use the correct capacity-specific listing before ordering. |
Install Overview
Before You Start
Turn Hold off, use the reset sequence for this generation, and confirm the model and variant before opening the iPod.
Treat case opening as the highest handling risk. Work around the seams gently and stop if the shell, clips, or internal stack resist.
Do not pull the halves apart or side-load board sockets. Reseat nearby ribbons and connectors before blaming a replacement battery.
Stop charging and avoid puncturing, bending, or compressing the cell if the battery is swollen, hot, leaking, or visibly damaged.
Disassembly Guide
Disassembly guide summary: iPod Mini Battery Replacement.
Show all 12 installation steps
Confirm that the hold switch is locked before you open the iPod.
Carefully slide a small flathead screwdriver or Jimmy into the seam between the metal casing and white plastic top. Lever up the white top bezel, taking care not to damage the soft plastic. The top bezel is adhesive-backed, so you may need to lever it up from several spots before it releases. Heat up the adhesive for a few seconds with a hair dryer on low heat to make the job easier.
Raise the top bezel off the iPod.
Carefully slide a small flathead screwdriver or Jimmy into the seam between the metal casing and white plastic bottom. Lever up the white bottom bezel, taking care not to damage the soft plastic.
A small pair of snap-ring pliers is the best tool to take out the metal retaining bracket. You can also lever out the metal retaining bracket beneath the bottom bezel with a flathead screwdriver. Release the bracket by pressing in the corner metal arms first.
Lift the released bracket away and set it aside.
With a spudger or fingertip, carefully detach the orange click wheel ribbon from the logic board. Do not dig the spudger in too deeply, or the logic board contact may detach. Keep the spudger as close as possible to the orange click wheel ribbon connector.
Take out the 2 #00 Phillips screws securing the headphone jack to the casing.
Carefully move the iPod out of its casing by pressing on the logic board near the click wheel's bottom edge. As you move the iPod out, small components may snag on the side of the casing. Move the device side to side to clear these components. Do not tug on the headphone jack board at the iPod top; its logic board connector is fragile. Take care not to break the logic board connector off the device. The ribbon cable sits at the very top of the connector.
After the logic board has been pushed out far enough, gently grip it on either side of the display and keep sliding the iPod from its casing.
Raise the battery off the logic board and set it to the side of the iPod.
Carefully detach the battery from the logic board. Make sure to draw only on the connector and not on the battery wires.
Product-specific placement, reassembly, and check
- Prepare and access. Confirm the exact model and listing fit first. Use the existing steps as a disassembly guide, gather the specified tools, disconnect power where applicable, and keep screws and cable positions organized.
- Place Replacement Battery. Seat the battery in the original battery location, route its lead or ribbon without a pinch, and reconnect it squarely.
- Reassemble without force. Reverse only the access steps needed for this repair, keep cables clear of case edges and screw posts, and close clips in stages.
- Validate before final closure. Before final closure, confirm boot and charging behavior and stop immediately for swelling, heat, odor, hissing, smoke, or leakage.
Stop condition: Stop if a connector, latch, screw, clip, housing edge, or the replacement part resists normal alignment. Recheck model fit, orientation, cable routing, and trapped hardware instead of forcing it.
After This Repair
| Check | What to do |
|---|---|
| Charge and calibrate | Charge fully, let it stay on the charger a little longer, then use it through a normal discharge and charge cycle so the meter can settle. |
| Watch the internal stack | If the display shows pressure marks, dark spots, or case bowing after reassembly, reopen and check battery thickness and cable routing. |
| Controls dead after the swap | The orange click-wheel ribbon is unplugged to get the case open, and owners report it as the commonest new fault after a battery job: the wheel scrolls and clicks nothing, or nothing at all responds, while the screen and charging are fine. Reopen, reseat that ribbon squarely on the logic board and refit the metal retaining bracket before ordering a click wheel. |
| Still not working? | Check the dock connector, battery connector, storage load, and board power path before replacing another battery. |
Battery Safety & Shipping
How to tell a pack has swollen on this model. The pack lies behind the display, so the signs show at the front and the seams: a lifted or bowed display panel, a dark blot or pressure mark spreading across the picture, a top or bottom bezel starting to lift, or a case that no longer sits flat. Held beside a new pack, a swollen one is visibly domed. Do not press a lifted panel or a raised bezel back down.
⚠️ Lithium-Ion / Li-Po Battery Safety. This product contains (or is) a rechargeable lithium-ion/lithium-polymer battery. Charge only with a compatible charger and unplug once fully charged. Avoid charging or storing in direct sunlight or other high-heat environments. Stop using and stop charging immediately if the battery swells, bulges, gets unusually hot, hisses, smokes, or leaks. Do not puncture, crush, bend, short-circuit, or try to "deflate" a swollen cell, and never press a lifted screen or case back down — it can rupture the cell. If electrolyte contacts your eyes, flush with clean water for 15 minutes without rubbing and seek medical care; on skin, wash with water and soap. Battery service should be done by a trained technician. Recycle through an electronics or universal-waste recycler, not household trash.
Shipping. A refurbished iPod shipped with its battery installed is handled as lithium-ion batteries contained in equipment (UN3481); a loose replacement cell is handled as a lithium-ion battery (UN3480). Carrier, packaging, and destination restrictions can vary, so follow the current checkout and shipping instructions for the offered route.
Worth Knowing
- Apple never published a capacity for this battery; replacement packs are labeled anywhere from 400 to 650 mAh under the EC003 / EC007 codes — treat the label as a label, and treat far higher numbers as relabels. Either code fits all Mini 2nd Generation units, and the same pack serves both mini generations. Replacement listings also appear under the dash-suffix battery codes EC007-3 and EC007-5 (repair guide part numbering for the same EC007 cell family).
- Full charge ~4 hours; 2 hours to 80% capacity. Those are Apple’s published figures for a new iPod mini of this generation, not a measurement of any replacement cell — use them as a rough expectation, never as a test result.
- A failing Mini shows the Sad iPod or folder icon, not the Red X. A red X is the iPod’s own diagnostic saying it cannot use its hard drive, and it belongs to later hard-drive iPods (Apple HT201544). If you searched "red x", run this listing's storage checks.
- No multi-part kit is needed for a Mini 2nd Generation battery swap — the pack and the included pry tool are all you need.
- Where the pack sits, and why that decides the symptom. On the mini the pack lies behind the display, so a cell that swells presses the screen — see Battery Safety & Shipping below for what that looks like. A stiff or dead center button is not the sign on this model; that mechanism belongs to iPods whose pack sits behind the click wheel.
- The battery icon. A lightning bolt across the battery icon means the battery is charging; Apple’s guide for this generation adds that if you do not see the lightning bolt the mini may not be on a high-power USB 2.0 port, so try another port. When the icon stops animating on a power source, the pack is full.
What Owners Report
These are anecdotal owner reports, not guarantees or authoritative proof that a particular part will fix a symptom. Use them as a troubleshooting starting point: confirm the symptom, run the quick checks, then match the fix.
Will not power on after a battery replacement
Symptoms. A fresh battery (in one case a new click wheel as well) goes in and the unit refuses to power on; the Apple logo comes up and stays there even on a charger; one owner sees a battery symbol with a lightning bolt and is unsure what it means; another simply asks where a replacement pack comes from.
Quick diagnosis.
- Open the case again and reseat every connector — battery plug, click-wheel flex, display. A loose connection is the classic cause when a unit goes dark right after a repair. The pack plugs in by a friction-fit connector: pull on the connector body, never on the wires.
- Plug it into a computer. If it powers up on the cable, restore it (on Windows, iTunes for Windows, or the newer Apple Devices app) and let the new pack take one full, uninterrupted charge before judging the repair. A restore erases the iPod, so copy anything that exists only on it first.
- If the unit still shows nothing, treat the replacement pack itself as a suspect — new packs can arrive dead, and warranty exchange is the documented resolution in this record.
Fixes.
- Reseat, restore, full charge — the sequence that clears most post-repair dead units: connectors first, then a restore, then a complete charge.
- Replacement pack — Apple never published a capacity for this battery; replacement packs are labeled anywhere from 400 to 650 mAh under the EC003 / EC007 codes — treat the label as a label, and treat far higher numbers as relabels. The same pack serves both mini generations.
- Exchange a dead-on-arrival pack — when the swap changes nothing and the connections are proven, the record's resolved case ended with a warranty exchange of the new pack.
Cautions.
- Never work on a swollen pack, and never pry at the cell itself.
- Buy the pack, not a wiring diagram: connector and wiring specifics for this model are not verified in any trusted source, so ignore listings that lead with them.

Will not hold charge, or charging a pack outside the unit
Symptoms. A hobbyist repairing several units wants to bench-charge spare packs before installing them; a recovered family keepsake unit appears to take a charge while plugged in but is dead the moment the cable comes out.
Quick diagnosis.
- In the unit, this generation charges and syncs over USB 2.0, with FireWire 400 as the second supported interface — a computer port is the everyday charge path. New units shipped with only a USB cable in the box; that says nothing about what the hardware supports.
- Appears-to-charge but dies-unplugged is the classic signature of a worn-out pack: the charge path works, the cell no longer stores anything. On a unit this old, the battery is the first suspect.
Fixes.
- Battery replacement — the standing fix for a pack that no longer holds charge: the pack and the included pry tool are all you need. Packs are the EC003/EC007 class shared across the mini family.
- Spare packs — charge the pack inside the iPod; bench-charging bare lithium cells is a fire risk we do not recommend.
Cautions.
- Never work on a swollen or damaged pack — that is a safety problem before it is a repair question.
- Data first: if the goal is rescuing music from an old unit, it will often run on cable power alone — copy the data off before any battery surgery.
- A listing keyed only to "A1051" fits both mini generations — for the battery that is harmless, since the pack is shared, but do not extend that trust to generation-specific parts.
Community signal. Reported by 2 owners.
A1051 stops at the Apple logo, then a folder with an exclamation point
Symptoms. The unit will not start: a dark Apple logo appears, then a folder icon with an exclamation point in a triangle, then nothing. The behavior was identical before and after a new battery went in — the owner replaced and charged the pack, and the icons stayed.
Quick diagnosis.
- A folder-with-exclamation stop is the software-fault class on this model — the thread's experienced voice reads it as incorrect or corrupted iPod software. A just-replaced, charged battery is not the suspect when the same icons appeared before the swap.
- Reading the listing or the back panel: A1051 is the model number of both mini generations, and a figure like "4 GB" describes storage capacity, not a generation — both generations sold a 4 GB size. On this generation the capacity is engraved on the back panel; the 6 GB size exists only here.
- Reset first — hold Menu + Select until the unit restarts — and watch whether the boot sequence changes. Guides that say Menu + Play describe the older, pre-click-wheel iPods.
Fixes.
- Restore — the surviving fix for corrupted iPod software, and on Windows that is iTunes for Windows, or the newer Apple Devices app. A restore erases the iPod, so copy anything that exists only on it first. The final software issued for this model is 1.4.1.
- The old standalone updater — Apple still hosts the January 2006 iPod Updater, but it only runs on Windows XP-era or Mac OS X 10.3.9-era computers; on anything current, restore through iTunes for Windows, or the newer Apple Devices app.
- Battery-connector reseat (owner-reported) — one owner cleared a frozen unit by disconnecting the battery for a few seconds and reconnecting it. Worth one try while the case is open.
- Drive next — if a restore will not complete and the folder icon returns, the fault class moves to the drive; the sad-face and storage entries on this model's pages carry that path.
Cautions.
- Do not go hunting for era-specific updater packages on a modern computer — they need the old systems above; the restore route is the current one.

Which mini is this, and which parts swap
Symptoms. An owner reads a model number off the back panel and asks which mini generation it belongs to; another, weighing the two generations, asks what actually differs and whether a battery from one fits the other.
Quick diagnosis.
- Every iPod mini carries the same model number — A1051, on both generations — so the number alone cannot answer the question. A reading like "A1050" is worth re-checking against the engraving, because A1051 is what the mini family prints.
- The reliable external tell is the capacity engraving: 4 GB or 6 GB printed on the back means this model; no capacity printed means the first-generation mini. This generation shipped in Silver, Blue, Pink and Green, with the click-wheel button text matched to the case color; the first-generation mini has gray inset wheel text on every color, no capacity engraving, and the Gold color this generation dropped.
- Backup discriminators for a worn back panel: the EMC number (EMC 2044 here, EMC 1984 on the first-generation mini), a 6 GB capacity (this generation only), or the order number (M9800LL/A, M9802LL/A, M9804LL/A, M9806LL/A — Silver, Blue, Pink, Green at 4 GB; M9801LL/A, M9803LL/A, M9805LL/A, M9807LL/A the same colors at 6 GB — an even final digit means 4 GB, odd means 6 GB).
What swaps, and what does not.
- Battery: shared — packs interchange between the two mini generations (the EC003/EC007 class); owners in this thread and the parts record agree.
- Drive flex cable and headphone jack: shared — the drive flex cable is one part for both mini generations (owner-verified), as is the headphone-jack assembly (820-1597-A).
- Click wheel: generation-matched only — wheels do not interchange between the generations in either direction. This generation's wheel is 632-0303-A, sold per case color; color-matched button text is its signature.
- Display: generation-matched by the printed-capacity rule — a screen pulled from a donor with no capacity mark on the back belongs to the first-generation mini and is the wrong part here; a donor engraved 4 GB or 6 GB matches.
- Logic board: two part numbers, both this generation — 820-1648-A and 820-1804-A are both 2nd-generation boards and either fits any 4GB or 6GB unit; the capacity lives on the drive, not the board.
Cautions.
- Never buy boards or wheels on "A1051" alone — the number is identical across both generations and identifies nothing. Insist on the capacity-engraving or EMC discriminator before paying for a generation-matched part.

Frequently Asked Questions
Use these questions to narrow the part path before ordering. They keep each answer focused on a different diagnostic or fitment decision.
What iPod Mini 2nd Generation models does this fit?
This Replacement Battery fits: M9800LL/A (4GB Silver), M9802LL/A (4GB Blue), M9804LL/A (4GB Pink), M9806LL/A (4GB Green), M9801LL/A (6GB Silver), M9803LL/A (6GB Blue), M9805LL/A (6GB Pink), M9807LL/A (6GB Green).
Do I need to solder?
No, this installation does not require soldering. Difficulty: Moderate. Estimated time: 25 - 45 minutes.
How do I know if this battery needs replacement?
Symptoms that can point to this battery include: Won't Charge, Won't Turn On, Shuts Down Randomly, Battery Drain. Check fitment, connectors, and nearby parts before treating symptoms as proof.
When is this battery the right fix for power or runtime symptoms?
Confirm this is the correct battery for the model-specific fitment and capacity before using symptoms to choose the part. Try a known-good USB cable or power source and note whether the iPod stays on only while connected. If the iPod was opened recently, inspect and reseat the battery connector before ordering another battery. If the drive clicks, shows a sad iPod, or fails restore under load, keep the storage path in the comparison before blaming only the battery. Test with a known-good charger and cable before opening the iPod. Note whether the iPod shows charging, briefly powers on, shuts down under load, or never wakes at all. If the symptom began after service, inspect the battery connector and nearby flex paths before replacing another part. This 4 GB / 6 GB battery is the right choice when runtime or charge retention is isolated to the battery path. Choose this battery only when the power, charging, or runtime pattern is tied to this part or its connector path. Check cable and power-source behavior, connector seating, swelling, corrosion, and storage symptoms before treating the battery as confirmed. Check charger/cable behavior, dock connector condition, storage startup clues, and board damage when the symptom is not isolated to battery performance. If a battery charges normally in one Mini generation but not the other, consider a logic board charging-path issue rather than assuming the battery is bad. A swollen or damaged lithium battery should be handled as a safety issue, not a normal quick fix.
Can storage trouble look like a bad battery?
Listen for repeated drive clicking and compare whether the symptom changes in disk mode or during restore. Reseat the hard-drive ribbon before replacing the battery again when power symptoms began after service. Listen for repeat clicking or repeated spin-up attempts before replacing storage parts. Check whether the iPod enters disk mode, restores cleanly, and is recognized by the computer. If a drive or flash adapter was just installed, recheck cable seating, adapter orientation, and formatting before buying another part.
What should I check before replacing this battery?
Inspect the battery connector and nearby ribbon paths before ordering another battery. Look for corrosion, torn flex material, or a connector that no longer clamps the battery lead cleanly. Reopen only as far as needed to inspect the areas touched during the repair. Compare the new symptom with what worked before the repair. Check cable seating, latch position, and part variant before replacing a second part.
Is this for a full-size hard-drive iPod?
The iPod mini is a separate Apple product line from full-size hard-drive iPods. This is the iPod mini 2nd Generation.
When is it unsafe to keep charging this iPod?
Stop immediately if the iPod smells burnt, the dock area looks melted, the battery is hot, swollen, or leaking, or liquid exposure is involved. Disconnect power, do not charge again, and inspect the battery, dock connector, and charge path before any further troubleshooting. A damaged lithium battery is a safety problem first and a repair question second.
