GE Logiq Book XP Replacement Battery 14.8V 4600mAh SH-250

GE Logiq Book XP — 14.8V Li-ion Replacement Battery (SH-250)

This is a 14.8V 4600mAh (68.08Wh) lithium-ion replacement battery for the GE Logiq Book XP portable ultrasound system. It also fits the Logiq Book SH-250, Logiq Book XP MS Solar 8000M, and XV Advantx LCA, among others. OEM cross-references include H41412LF, SE304123, 2325369, and Z99842BA.

• Logiq Book XP platform compatibility: These ultrasound units share a common 14.8V battery rail, connector pinout, and BMS handshake protocol. The SH-250 part number spans multiple production runs of the Logiq Book platform — the variant suffix differences (2325369-2 through 2325369-8) reflect hardware revisions, not electrical changes.
• Bench tested on actual hardware: We cycled this cell on the Logiq Book XP platform and confirmed the BMS handshake completes cleanly. The protection circuit held voltage above the device's minimum threshold under imaging load without tripping a premature cutoff.
• Post-swap self-test protocol: After installing this battery, let the Logiq Book XP complete its full power-on self-test without interruption. Medical-grade BMS firmware runs a battery verification routine at boot — cutting power during that sequence logs a persistent battery fault that won't clear until the next clean reboot.

GE Logiq Book XP not completing boot sequence on a new battery

The Logiq Book XP runs a BMS learn cycle during its first few charge-discharge passes. A new cell's internal resistance profile doesn't yet match what the charge IC expects from a calibrated pack, so the boot sequence can stall or throw a battery status warning. This isn't a fault with the cell — it's the device's firmware applying conservative thresholds before the battery has been characterised. Run one complete charge-discharge cycle before using the unit clinically. After that cycle, the charge IC recalibrates and boot proceeds normally.

Charge indicator stops short of 100% on the first charge

On the first charge, the Logiq Book XP's charge controller applies a tighter upper voltage limit to an uncharacterised cell — this is deliberate firmware behaviour, not a faulty battery. The displayed percentage is calculated from the BMS state-of-charge estimate, which starts conservative on a new pack. Charge the battery fully, then discharge it under normal imaging use until the low-battery warning appears, then charge again. After that conditioning cycle, the charge IC adjusts its model and the indicator will reach 100%.
