I-Mate PDA-N GALA160 Replacement Battery 3.7V 1100mAh

I-Mate PDA-N — 3.7V Li-ion Replacement Battery (GALA160)

This 3.7V 1100mAh Li-ion battery replaces the original cell in the I-Mate PDA-N handheld computer. It fits directly using OEM part numbers GALA160 and 35H00063-01M. When the original cell degrades and no longer holds adequate charge, this replacement restores the device to full operational capacity.

• PDA-N platform fit: The PDA-N uses a 3.7V single-cell Li-ion pack with a BMS that monitors cell voltage and temperature. This replacement matches the OEM voltage rail and connector pinout, so the device firmware reads charge state correctly without recalibration prompts.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The BMS communicated correctly with the host device throughout, reporting accurate charge state and triggering low-battery warnings at the expected voltage threshold.
• RAM data protection before swap: The PDA-N stores open files and application state in volatile SRAM powered directly by the main battery. Sync all data to a host computer using ActiveSync before removing the old cell — pulling the battery without syncing will erase any unsaved records or open application data.

PDA-N losing data after battery swap

The PDA-N holds active data — open contacts, calendar entries, unsaved notes — in SRAM that requires continuous battery voltage to retain its contents. The moment the old cell is removed and before the new one seats, that voltage drops to zero. Even a brief interruption wipes everything stored in RAM. To avoid this, run a full ActiveSync backup to the host PC, confirm the sync completed, then swap the battery. After installing the replacement, allow the device to boot fully before opening any applications.

PDA-N not booting after new battery installed

A freshly installed replacement cell may not carry enough charge from storage to clear the PDA-N's minimum boot voltage threshold. If the device shows nothing on screen or displays a low-battery icon immediately after installation, the cell simply needs a charge before the first boot attempt. Connect the device to its original charger and leave it for at least 30 minutes before pressing the power button. The boot sequence requires a stable supply above approximately 3.4V to complete without locking at the splash screen.
