Molift AIR 2510023 Replacement Battery 26.4V 3000mAh

Molift AIR 2510023 / Air 300 — 26.4V Ni-MH Replacement Battery (2510023)

This is a 26.4V, 3000mAh Ni-MH replacement battery for the Molift AIR 2510023 and Air 300 patient lift systems. It powers the electric drive motor and control circuitry used during patient transfers in hospitals, care facilities, and home care. It also covers the HI-TRAC and compatible Molift hoist platforms that share the same 26.4V battery bay and connector spec.

• AIR 2510023 / Air 300 / HI-TRAC platform fit: These models share a 26.4V supply rail, the same physical housing dimensions (135.20 × 80.60 × 48.30mm), and an identical BMS handshake protocol. One battery covers the full range.
• Bench tested on actual hardware: We ran charge-discharge cycles through the Molift BMS and confirmed the protection circuit trips correctly at both the high-voltage and low-voltage cutoff thresholds. Cell balance across the Ni-MH pack stayed within spec through the first five cycles.
• Post-swap power-on protocol: After fitting this battery, let the device complete its full power-on self-test without interruption. The BMS runs a verification sequence at startup — cutting power mid-cycle flags a false battery fault that persists until the next complete reboot.

Why the Molift AIR alarms low battery immediately after a confirmed full charge

The Molift BMS stores chemistry calibration data from the OEM cell. A new replacement cell has no charge history, so the BMS applies its most conservative capacity threshold on the first read — often flagging a fault even when the cell is fully charged. This is not a defective battery. Run one complete charge-discharge cycle through normal operation and the BMS will recalibrate its state-of-charge estimate. After that cycle, the low-battery alarm will trigger at the correct threshold.

Molift lift unit shows no response after battery sat unused in storage

Ni-MH cells self-discharge during storage — if the pack drops below approximately 20V, the Molift BMS locks out to prevent cell reversal damage. A standard charger will not recover a pack in deep lock-out because the charge IC sees voltage below its minimum start threshold. Connect the battery to the OEM Molift charger and hold the charge connection for at least 60 seconds — most Molift chargers apply a trickle pre-charge pulse that brings the pack above the 22V recovery floor before switching to normal charge mode.
