Battery for legacy Palm handhelds

This Cameron & Co Li-Polymer cell replaces the original power pack in Palm M550, Tungsten T1, T2, T3, Zire 31, Zire 71 and Zire 72 models. It delivers 3.7 V and 1100 mAh in a black 51.06 x 33.02 x 5.32 mm housing that fits the original battery bay without modification. The pack is aimed at owners keeping these organisers running for daily scheduling, contact lookup or e-book reading.

Steady output for intermittent use

The 1.1 Ah capacity supports typical PDA workloads — short bursts of screen-on time separated by long standby periods — rather than continuous high-drain discharge. Internal resistance remains stable across repeated charge cycles, so voltage sag during a sync operation or backlight activation stays minimal. The chemistry is rated for hundreds of full cycles before capacity drops below 80 % of the rated figure.

Direct swap for OEM part numbers

This unit cross-references GA1W918A2, GA1W922A2, IA1T923A0, IA1TA16A0, IA1W416A2, IA1W721H2 and PBA80860US, covering every factory battery shipped with the listed Palm models. The jump is worth it when the original cell no longer holds a charge through a working day or shows physical swelling. It is not for devices that require a different voltage, connector pitch or form factor.
