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

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 | Follow the remaining storage, display, audio, port, or board clue instead of replacing another battery. |
| Only the screen is affected and everything else works | Start with the screen, display ribbon, backlight path, and battery-swelling inspection. |
| A symptom points to a different part | Start with hard-drive cable for folder, clicking, or restore symptoms; dock-port bracket for dock, sync, or charge-port symptoms; 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.
Repair Guide
Repair 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.
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. |
| Still not working? | Check the dock connector, battery connector, storage load, and board power path before replacing another battery. |
Battery Safety & Shipping
⚠️ Lithium-Ion / Li-Po Battery Safety. This product contains (or is) a rechargeable lithium-ion/lithium-polymer battery. Charge only with a compatible charger; don't leave it charging unattended or overnight, 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 ships as UN3481 (lithium-ion batteries contained in equipment); a loose replacement cell shipped on its own ships as UN3480 (lithium-ion batteries). Cells have passed UN Manual of Tests and Criteria 38.3 testing.
Worth Knowing
- EC003 and EC007 are the common replacement-market battery codes (replacement capacity is typically 550-650 mAh); either fits all Mini 2nd Generation units. 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.
- A failing Mini shows the Sad iPod or folder icon, not the Red X — the Red X 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 replacement cell ships with the pry tool included.
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. This battery may still help when runtime is poor after storage symptoms are ruled out. Choose this battery only when clicking, restore failure, or disk errors follow this part or its connection path. Check the storage path first when sad iPod, clicking, or restore failure is the main event. Check the storage cable, adapter setup, battery power stability, and board connector when the symptom changes after reseating or swapping storage.
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. This battery helps only when the battery itself remains the isolated failure after seating checks. Choose this battery only when the part itself was torn, creased, or damaged during service. Check disturbed connectors first when the symptom appeared immediately after service. Check the exact connector or assembly disturbed during the repair before treating the new part as failed.
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.
