Cameron & Co DS-CS-PM150SL 650mAh Li-ion Battery for Palm M150 M155 Zire 21 22

Compatible Palm models

This replacement battery fits the Palm M150, M155, Zire 21 and Zire 22. It restores power to those specific Pocket PC PDAs when the original cell no longer holds a charge. Buyers with other Palm devices or newer smartphones cannot use this pack.

3.7 V 650 mAh lithium-ion limits

The cell delivers 3.7 volts and 0.65 Ah, which matches the factory specification for the listed models. Runtime will reflect the capacity of the original battery; heavier backlight use or constant wireless activity will drain it faster. No higher-capacity version is offered in this form factor.

Slim black pack with OEM fit

The lithium-ion pack measures 50.92 x 30.61 x 4.74 mm and comes in black, matching the original dimensions for a flush fit inside the battery compartment. No adhesive or tools beyond the device's own latch are required for installation. The 100 % OEM-compatible claim means the connector aligns with the M150, M155, Zire 21 and Zire 22 without modification.
