Palm LifeDriver 3.7V 1800mAh Li-ion Replacement Battery

Palm LifeDrive — 3.7V Li-ion Replacement Battery (1UF463450F-2-INA)

This is a 3.7V, 1800mAh Li-ion replacement battery for the Palm LifeDrive PDA. It replaces OEM part 1UF463450F-2-INA and fits the LifeDrive's battery bay directly. Voltage and capacity match the original spec so the device's processor, display, and storage operate normally.

• LifeDrive compatibility: The LifeDrive uses a single-cell Li-ion pack at 3.7V nominal. The BMS on this device monitors cell voltage and will not complete a boot sequence if the pack sits below minimum threshold — this replacement meets that floor from a charged state.
• Bench tested on actual hardware: We cycled this battery on the LifeDrive platform and confirmed the BMS accepted charge from the cradle without fault codes, held charge through standby, and released cleanly through full discharge cycles. No charge-detection errors were logged.
• RAM data preservation before swap: The LifeDrive holds open application state and unsaved data in SRAM powered directly by the main battery. Sync all data to your host PC or Mac using HotSync before removing the old battery — anything not synced will be lost the moment the cell is disconnected.

Why the LifeDrive won't boot after a new battery is installed

The LifeDrive's boot sequence draws a short surge of current to spin up the internal hard drive. If the replacement battery arrived partially discharged — common after months in a warehouse — its voltage can sit too low to pass the device's startup check. The unit will either show a blank screen or a low-battery warning immediately. Place the device in its cradle and charge for at least two hours before attempting to power on. Once the battery reaches an adequate voltage, the boot sequence completes normally.

LifeDrive battery draining faster than expected during Wi-Fi sync

The LifeDrive's integrated Wi-Fi radio draws substantially more current than standby or basic application use. A battery that reads full under light use can sag noticeably during a wireless HotSync session because the radio sustains elevated current draw throughout the transfer. If sync sessions are dropping or the device powers off partway through, check that the battery is at a full charge — above 4.1V — before starting the sync. Switching to a wired cradle sync removes the radio draw entirely and completes the transfer at a fraction of the power cost.
