Estry standard battery 1100mAh 3.7V for Palm Zire Tungsten M550

Replacement Battery for Palm Handhelds

This Estry lithium cell is a direct replacement for several Palm Zire and Tungsten models including the M550, Tungsten T1, T2, T3, Zire 31, Zire 71, Zire 72 and Zire 72s. It matches the original specifications with a capacity of 1100mAh and a voltage of 3.7V. The pack includes a single battery built to the same dimensions as the OEM unit. Safety circuits provide overcharge, over-discharge, over-voltage and short-circuit protection.

Suitable for Restoring Original Runtime

Owners of the listed Palm devices who need to replace an ageing or failed battery will find this unit restores the factory runtime. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirming compliance with quality and safety standards. Buyers who require a higher capacity than 1100mAh or a different form factor should look at other options. The battery is not compatible with devices outside the specified model list.

Capacity and Practical Limits

The 1100mAh rating delivers the same energy budget as the original battery, supporting typical daily use of the compatible Palm organisers. Runtime will vary with screen brightness, wireless activity and application load. When the cell no longer holds sufficient charge for a full work day, it has reached its practical limit and should be replaced again. No capacity beyond the stated 1100mAh is available in this form factor.
