Replacement Battery for Max Wireless Handsets

This Estry Ni-MH pack replaces the original power source in Max Wireless 592-158-001, 592-158-002 and 592-158-003 devices. It matches the factory voltage of 7.2V and capacity of 2000mAh for direct fit and function. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Who This Suits and Who Should Look Elsewhere

Owners of the listed Max Wireless models needing a fresh 7.2V 2000mAh pack will find a direct match. Buyers whose equipment requires a different voltage, a higher capacity or a Li-ion chemistry cannot use this unit. It is not suitable for devices that specify a proprietary connector or form factor other than the 220AAH6SMLZ footprint.

Deciding Specification — Voltage and Capacity

The single figure that decides fit is the 7.2V 2000mAh rating delivering 14.4Wh. If the original battery label shows the same voltage and capacity this pack will work; if either value differs the replacement will not power the device correctly.
