Sony Xperia Tablet Z 10.1" LIS3096ERPC Replacement Battery 3.7V 6000mAh

Sony Xperia Tablet Z 10.1" — 3.7V Li-Polymer Replacement Battery (LIS3096ERPC)

This 3.7V, 6000mAh (22.2Wh) lithium-polymer cell replaces the original LIS3096ERPC battery in the Sony Xperia Tablet Z 10.1". It fits the SGP321 and SO-03E variants. The flat pouch format matches the original cell's 202.25 × 121.56 × 2.72mm footprint exactly.

• SGP321 and SO-03E compatibility: Both variants use the same charge IC, connector pinout, and BMS handshake protocol. The LIS3096ERPC cell communicates cell temperature and state-of-charge data directly to the tablet's power management unit — the replacement cell carries the same data line configuration.
• Bench tested on actual hardware: We cycled this cell through the Xperia Tablet Z charge controller and monitored BMS communication. The protection circuit responded correctly to the tablet's charge cutoff at 4.2V and engaged low-voltage cutoff without triggering a false fault state.
• Fuel gauge recalibration after swap: After installation, run the tablet down to automatic shutoff, then charge in one uninterrupted session to 100%. This forces the fuel gauge IC to map its reference points against the new cell and clears the percentage drift that appears immediately after a battery swap.

Xperia Tablet Z shutting down at 15–25% remaining

The Xperia Tablet Z runs a 10.1-inch display alongside WiFi and background processes simultaneously. Under that combined load, cell voltage drops faster than the fuel gauge IC can report. When voltage hits the protection circuit's cutoff threshold, the tablet shuts off even though the percentage counter still shows charge remaining. After fitting this replacement cell, run one full discharge cycle so the fuel gauge recalibrates its voltage-to-percentage curve against the new cell's actual characteristics. Unexpected shutdowns should stop once the gauge references the correct voltage floor — typically around 3.3V under load.

Fast charging not available after battery replacement

The Xperia Tablet Z's charge IC uses a negotiation handshake on the first accepted charge cycle to confirm cell parameters before enabling higher charge rates. A freshly installed cell has no prior negotiation history stored. Plug the tablet into the original Sony charger — not a third-party adapter — and allow the first charge to complete fully without interruption. After that initial full cycle, the charge IC logs the accepted parameters and fast charging becomes available on subsequent sessions.
