Google Nexus 10 Replacement Battery 3.7V 8000mAh SP3496A8H

Google Nexus 10 — 3.7V Li-Polymer Replacement Battery (SP3496A8H)

This is a 3.7V, 8000mAh Li-Polymer replacement battery for the Google Nexus 10 tablet. It fits the 10-inch Android tablet released in 2012 and matches the original SP3496A8H cell configuration. Swap it in when the original cell no longer holds enough charge to keep the tablet usable away from a wall.

• Nexus 10 fitment: The Nexus 10 uses a 1S2P Li-Polymer pack at 3.7V with a specific connector and BMS handshake that communicates state-of-charge to Android's battery service. This replacement matches that connector pinout and BMS protocol so the OS reads cell data correctly from first boot.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Nexus 10 board. The BMS communicated correctly with the charge IC, reported accurate voltage to the system, and held full charge without triggering a thermal or overvoltage cutoff event.
• Post-installation fuel gauge reset: After fitting this battery, run the tablet down to automatic shutoff, then charge it uninterrupted to 100%. The Nexus 10's fuel gauge IC is calibrated against the old cell's capacity curve — this one full cycle resets that calibration to the new cell and corrects the inaccurate percentage readings that appear right after a swap.

Why the Nexus 10 shuts down at 15–25% remaining after a battery swap

The Nexus 10's fuel gauge IC stores a learned capacity model from the original cell. When a new cell is installed, that model no longer matches the actual voltage-to-capacity curve of the replacement. At high-load moments — full display brightness combined with active Wi-Fi — the cell voltage dips sharply, and the old model interprets that dip as a depleted cell. The tablet shuts down even though usable charge remains. One complete discharge-to-shutoff followed by a full uninterrupted charge retrains the model against the new cell's curve.

Nexus 10 showing wrong battery percentage after replacement

After fitting a replacement cell, Android's battery percentage can jump, stall, or read 10–15% lower than actual charge. This happens because the fuel gauge IC was calibrated to the degraded capacity of the original cell — it's measuring the new cell against a baseline that no longer applies. The fix is one full calibration cycle: discharge the tablet to automatic shutoff, then plug in and charge to 100% without interruption. After that cycle completes, the percentage display tracks the actual cell state accurately.
