Battery Care Tips
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
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 — 3.7V Li-Polymer Replacement Battery (616-0627)
This is a 3.7V, 4490mAh Li-Polymer battery for the Apple iPad Mini, covering A1432, A1454, A1455, and related Wi-Fi and cellular variants. It replaces the original cell when the tablet no longer holds a charge, shuts down unexpectedly, or fails to power on. Fits the physical footprint at 151.22 × 98.66 × 2.21mm with the original ZIF connector.
- iPad Mini A1432 / A1454 / A1455 fit: All three models share the same battery bay dimensions, ZIF connector pinout, and charge IC handshake — the same cell works across Wi-Fi-only and cellular variants without modification.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on an iPad Mini A1432. The BMS engaged charge termination cleanly at 4.2V and held low-voltage cutoff without false triggers under display-plus-radio load.
- Fuel gauge reset after installation: After fitting this battery, run the iPad down to automatic shutoff, then charge uninterrupted to 100%. This gives the fuel gauge IC a full reference cycle against the new cell and clears the inaccurate percentage readings that almost always appear after a swap.
iPad Mini shutting down at 15–25% remaining
This happens when the original cell's internal resistance has climbed high enough that combined display and Wi-Fi load pulls the voltage below the BMS cutoff threshold — even though the reported percentage still looks safe. The fuel gauge IC was calibrated to the degraded cell, so its 20% reading no longer maps to a real voltage level. A new cell fixes the underlying voltage sag, but the gauge still needs one full discharge-to-shutoff cycle to recalibrate. After that cycle, unexpected cutoffs at 15–25% stop occurring.
iPad Mini showing wrong battery percentage after battery replacement
The fuel gauge IC in the iPad Mini learns the capacity curve of the cell it was last calibrated against. Drop in a new cell and the IC is still referencing the old cell's data, so it reports percentages that jump, stall, or read high until the device cuts off. Run one full discharge to automatic shutoff, then charge in one uninterrupted session to 100%. The IC uses that cycle to map voltage to capacity on the new cell. After a single complete cycle, percentage display stabilises.

Frequently Asked Questions
My iPad Mini keeps dying at around 20% — will a new battery fix that or is it something else?
In most cases it is the battery. When the original cell ages, its internal resistance climbs and the voltage collapses under combined display and Wi-Fi draw before the percentage gauge reaches zero. The BMS trips the cutoff at what looks like 20% because the old cell simply cannot deliver the current that level of load demands. Replace the cell, run one full discharge-to-shutoff calibration cycle, and the early shutoffs stop.
Fast charging stopped working after I swapped the battery in my iPad Mini — what happened?
The iPad Mini's charge IC needs at least one completed charge cycle before it fully negotiates with a new cell. Plug into the original Apple charger and cable — not a third-party USB-C adapter — and let it run from low to 100% without interruption. If fast charging still does not activate after that cycle, check that the ZIF connector is fully seated, since a partially connected battery causes the charge IC to default to a trickle-charge fallback rate.
The percentage on my iPad Mini drops fast from 100% then seems to slow down mid-charge — is the new battery faulty?
It is almost always fuel gauge drift, not a faulty cell. The gauge IC was calibrated to the old battery's capacity curve, so its percentage readings are inaccurate until it learns the new cell. Run the iPad down to automatic shutoff, then charge in one uninterrupted session to 100%. That gives the IC a full reference sweep of the new cell's voltage range, and the percentage drop rate normalises after that single cycle.
