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 A2898 / A2899 / A2900 / A2903 — 3.76V Li-Polymer Replacement Battery (0090S)
This 3.76V, 9700mAh (36.47Wh) lithium-polymer cell replaces the internal battery in Apple iPad models A2898, A2899, A2900, and A2903. It fits the standard battery bay on these tablets with no modification to the housing or connectors. Swap it in when the original cell no longer holds a charge or causes unexpected shutdowns.
- A2898–A2903 compatibility: These four model numbers share the same battery bay dimensions, connector pinout, and BMS handshake protocol — all four draw from the same 3.76V cell architecture, so one cell covers all variants without adaptation.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on iPad hardware. The BMS accepted charge negotiation without error flags, and protection circuits tripped correctly at both high and low voltage thresholds.
- Post-installation calibration: After fitting this cell, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without using it. This resets the fuel gauge IC against the new cell's actual capacity curve and clears the percentage drift that almost always appears after a swap.
iPad shutting down at 15–25% battery remaining after replacement
This happens because the fuel gauge IC is still calibrated to the old cell's voltage curve. The new cell hits a steeper voltage drop under combined display and Wi-Fi load than the IC expects — so it interprets a voltage cliff as an empty battery and forces shutdown. The fix is one full discharge-to-cutoff cycle followed by a full uninterrupted charge. After that cycle, the gauge recalibrates to the new cell and the early shutdowns stop. If shutdowns persist past 20%, check that the connector is fully seated — a partial connection raises internal resistance and exaggerates the voltage sag.
Fast charging not available after battery swap
Apple's USB-PD negotiation requires at least one completed charge cycle before the charge IC on a new cell accepts higher current without dropping back to standard 5W charging. This is a protection behaviour in the cell's BMS, not a fault in the replacement battery. Charge the tablet once from low to 100% at standard rate using Apple's own cable and adapter. After that cycle completes, USB-PD negotiation resumes normally and fast charge becomes available again.

Frequently Asked Questions
My iPad shows 80% battery but shuts off without warning — why is this happening after the battery swap?
The fuel gauge IC is still reading the old cell's voltage map. The new cell has a different voltage-drop curve under load, so the iPad calls empty at a point the old cell never would have. Run one full discharge to automatic shutoff, then charge uninterrupted to 100%. That single cycle recalibrates the gauge against the new cell and stops the premature shutdowns.
The battery percentage is jumping around — it reads 60%, then skips to 45% a few minutes later. Is the new cell faulty?
It isn't a faulty cell — it's a calibration gap between the fuel gauge IC and the new cell's capacity curve. The IC learned the old battery's charge profile over hundreds of cycles and that data doesn't transfer to a new cell automatically. Run one complete discharge-to-cutoff followed by a full uninterrupted charge to 100%. After that cycle, percentage readings stabilise and the erratic jumps clear up.
The iPad feels warm near the back during the first few charges after the battery swap — is that normal?
Yes. A new lithium-polymer cell runs slightly warmer than a degraded cell during initial charge cycles because the charge IC is pushing current into a cell with full electrochemical resistance — the old cell had reduced capacity and lower resistance from degradation. Warmth during charging on a flat surface is expected for the first two to three cycles. If the tablet gets hot to the touch or the charge IC logs a thermal warning in diagnostics, check that the battery connector is fully seated and the adhesive isn't pinching the cell.
