Apple iPad Mini 2 A1489 Replacement Battery 3.7V 6400mAh

Up to 20% off
New arrival
From $39.99 USD $49.99
Shipping calculated at checkout.
Replaces Apple A1489 and A1512 batteries in iPad Mini 2 and iPad Mini 3 tablets.
3.7V at 6400mAh delivers the capacity your tablet needs for a full charge cycle without voltage sag during display and WiFi use.
Connector slides straight into the original slot with no adapter required — locking tab seats flush against the retention clip.
We ran full discharge cycles on the test unit; the BMS accepted negotiation on first insertion and showed stable voltage under combined display load.
After installation, run one full discharge to automatic shutoff then charge uninterrupted to 100% — this resets the fuel gauge IC calibration against the new cell and resolves inaccurate percentage display that appears after a swap.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Apple iPad Mini 2 / Mini 3 — 3.7V Li-Polymer Replacement Battery (A1489 / A1512)

This 3.7V, 6400mAh lithium-polymer battery replaces the original cell in the Apple iPad Mini 2 and iPad Mini 3 tablets. It fits models A1489, A1490, and related variants. Voltage and capacity match OEM specifications so the charge IC operates without modification.

  • iPad Mini 2 and Mini 3 compatibility: Both generations share the same battery footprint, connector pinout, and BMS communication protocol — the charge IC on the logic board expects the same voltage curve and thermistor response from either model's battery slot.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on an iPad Mini 2 logic board, confirming BMS handshake, charge termination at full capacity, and stable voltage output under combined display and WiFi load.
  • Fuel gauge recalibration after swap: After installation, run the tablet down to automatic shutoff — do not force-power-off — then charge uninterrupted to 100% without using the device. This lets the fuel gauge IC map its low-voltage and high-voltage thresholds against the new cell's actual curve and clears the inaccurate percentage readings that appear after a swap.

iPad Mini 3 shutting down at 15–25% battery remaining

The Mini 3 display and WiFi radio together pull enough current that the battery voltage dips sharply near the bottom of its discharge curve. The fuel gauge IC, still calibrated to the old cell's internal resistance profile, interprets that voltage sag as empty and triggers an OS shutdown. The actual cell still holds charge — the IC just hits its cutoff threshold early. One full recalibration cycle corrects the threshold mapping and typically pushes the shutdown point below 5%.

Fast charging not resuming after battery replacement on iPad Mini 2

The iPad Mini 2 uses Apple's proprietary charge negotiation rather than USB-PD, and the charge IC sometimes defaults to a conservative current limit on the first cycle with a new cell. This is a protection behaviour — the IC hasn't yet confirmed the new cell's thermal and voltage response. Plug in with the original Apple adapter and leave it charging uninterrupted through one complete cycle. After that first accepted cycle, the IC unlocks its normal charge rate.

Frequently Asked Questions

My iPad Mini 2 shows 80% battery but shuts off without warning — is the replacement battery faulty?

The cell itself is not the issue. The fuel gauge IC is calibrated to the resistance profile of the old, degraded cell and misreads the new cell's voltage curve at the low end. Run the tablet down to automatic shutoff without forcing a power-off, then charge uninterrupted to 100%. That single full cycle resets the IC's thresholds against the new cell and stops the premature shutdowns.

The battery percentage on my iPad Mini 3 is jumping around — it dropped from 60% to 31% in minutes after the swap.

Percentage jumps after a battery swap are a fuel gauge drift problem, not a cell defect. The gauge IC stored calibration data from the old battery and is applying it to a cell with a different discharge curve. Do one complete discharge to automatic shutoff, then a full uninterrupted charge to 100% without using the tablet. After that cycle, percentage readings stabilise because the IC has mapped the new cell's actual voltage range from 3.0V at empty to 4.2V at full.

My iPad Mini 2 feels warm near the top edge while charging after the battery replacement — should I stop charging it?

Warmth near the top edge during the first few charge cycles is normal. The charge IC on a new lithium-polymer cell runs a higher initial charge current while it characterises the cell, which generates more heat than a broken-in cell would. Surface temperature stays within Apple's charge IC safety window. If the device becomes hot enough to be uncomfortable to hold, or if charging stops and does not resume, disconnect and check that the battery connector is fully seated flat against the logic board socket.
