Xplore RSL10 Replacement Battery LYNPL03 7.6V 13000mAh

Xplore RSL10 / Xslate L10 — 7.6V Li-ion Replacement Battery (LYNPL03)

This is a 7.6V, 13000mAh (98.8Wh) Li-ion battery for the Xplore RSL10, XLBE1, and Xslate L10 rugged tablets. It replaces OEM part number LYNPL03 directly. If your original pack has degraded after field use, this restores full charge capacity.

• RSL10, XLBE1, and Xslate L10 compatibility: All three models share the same battery bay geometry, connector pinout, and BMS handshake protocol — the same 7.6V cell and fuel gauge IC applies across the group without hardware modification.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on the RSL10 platform. The BMS accepted the charge cycle without tripping an over-voltage fault, and cell balancing completed normally at full capacity.
• Fuel gauge IC reset after installation: After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This recalibrates the fuel gauge IC against the new cell and corrects the inaccurate percentage readings that commonly appear following a battery swap.

RSL10 shutting down at 15–25% battery remaining

This happens when the fuel gauge IC is still calibrated to the old, degraded cell. The tablet's power manager sees a voltage cliff — a rapid drop under the combined load of the display, WiFi radio, and active applications — and triggers a protective shutdown before the reported percentage reaches zero. The new cell has a flatter discharge curve than a worn pack, so the old calibration data no longer maps accurately to actual remaining charge. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% to resync the gauge.

Fast charging not available after fitting the LYNPL03

The RSL10 uses a USB-PD negotiation sequence to unlock higher charge rates. On a freshly installed cell, the charge IC needs to complete at least one accepted full cycle before the tablet's firmware confirms the pack as valid and enables the fast-charge profile. If fast charging is unavailable immediately after the swap, charge the tablet to 100% using the OEM charger at standard rate first. After that cycle completes, USB-PD fast charging should re-engage on the next charge session.
