Xplore XLBM1 Replacement Battery 7.4V 4550mAh Li-ion

Xplore XLBM1 — 7.4V Li-ion Replacement Battery (LynPD5O3)

This is a 7.4V, 4550mAh (33.67Wh) Li-ion replacement battery for the Xplore XLBM1 ruggedized tablet. It also covers units referenced under OEM part numbers 0B23-023U000P and 01H4000P. If your original battery no longer holds a charge or capacity has dropped noticeably, this cell restores full operation.

• XLBM1 and variant compatibility: The XLBM1 platform shares a single battery footprint across its variants. The connector pinout, BMS handshake protocol, and physical dimensions — 100.85 × 79.35 × 14.60mm — are consistent across units listed under these OEM numbers.
• Bench tested on actual hardware: We ran this battery through charge and discharge cycles on the XLBM1 platform. The BMS communicated correctly with the tablet's fuel gauge IC and accepted charge without fault flags or thermal cutoff events.
• Fuel gauge IC reset after installation: After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to calibrate against the new cell's actual capacity and eliminates the inaccurate percentage reading that typically appears after a swap.

Why the XLBM1 shuts down between 15–25% remaining

The XLBM1 runs a high-resolution display alongside active WiFi — both draw simultaneously and create a sharper voltage drop than either load alone. When the cell voltage sags under this combined load, the BMS reads it as a critically low state and triggers an immediate shutdown before the OS percentage reaches zero. This happens most often with an uncalibrated fuel gauge that has not yet mapped the new cell's discharge curve. Run one full discharge-to-cutoff cycle and the BMS will track the voltage curve accurately, preventing early shutdowns.

Fast charging not available after fitting a new XLBM1 battery

The XLBM1's charge controller uses a protocol negotiation cycle before it permits fast charge rates on a new or replacement cell. On the first charge after installation, the controller defaults to standard rate as a safety measure. Once that initial accepted charge cycle completes fully, the tablet re-enables fast charge on subsequent connections. If fast charge still does not appear after a full first cycle, verify the charger output meets the tablet's USB-PD specification — insufficient adapter wattage blocks the negotiation regardless of battery condition.
