About this replacement
Acer S10 / S50 / S60 — 3.7V Li-ion Replacement Battery (23.20059011)
This is a 3.7V, 1050mAh Li-ion battery for the Acer S10, S50, and S60 handheld PDAs. It matches OEM part number 23.20059011 and fits the same physical bay across all three models. Voltage and capacity figures come from the product data — 3.89Wh total energy.
- S10, S50, and S60 share this cell: All three models run the same 3.7V battery rail, use the same connector pinout, and accept the same BMS handshake. A battery pulled from an S50 slots directly into an S10 — the BMS does not differentiate between models at the hardware level.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on a PDA test rig. The BMS held cutoff voltage correctly at the low end and accepted a full charge without fault flags. Capacity measured within expected tolerance of the 1050mAh rating.
- Sync before you swap: PDA devices store open files and application state in RAM powered directly by the main battery. Removing the cell without first syncing to a host computer will wipe any unsaved data. Run a full ActiveSync or Windows Mobile Device Center sync before pulling the battery.
Why the Acer S10 loses data every time the battery is removed
The S10 uses SRAM for active storage — it holds the current application state, open files, and user session data. SRAM is volatile: it needs continuous power to retain data. The moment the battery is disconnected, that RAM is wiped. There is no flash backup for in-session data unless the device was synced or the user manually saved. This is not a fault — it is how the platform was built.
Acer S60 not booting after new battery installed
A fresh cell shipped in storage mode may sit below the minimum boot voltage — typically under 3.4V — which prevents the S60 from completing its POST sequence. The device will appear dead even though the battery and hardware are both fine. Connect the device to its charger for at least 20–30 minutes before attempting a first boot. Once the cell reads above 3.6V, the boot sequence will complete normally.
