Estry 3.6 V 600 mAh Ni-MH replacement battery

This Estry cell is a direct replacement for the original Radio Shack 431036 pack and the long list of compatible model numbers that share the same form factor. It suits owners of legacy cordless phones, emergency lights or portable devices that require a 3.6 V nickel-metal-hydride pack with a 600 mAh rating. Buyers who need a different voltage, chemistry or capacity should look elsewhere.

Thermal and power behaviour in normal use

Nickel-metal-hydride chemistry delivers a steady 3.6 V nominal output with minimal self-heating during typical charge and discharge cycles. The pack includes over-charge, over-discharge, over-voltage and short-circuit protection circuits that keep temperatures low and prevent noisy thermal events. No active cooling is required and the cell operates silently in the host device.

Deciding specification: 600 mAh capacity at 3.6 V

The single figure that determines fit is the 600 mAh capacity combined with the 3.6 V nominal voltage, yielding 2.16 Wh of stored energy. If the original equipment calls for a higher or lower milliampere-hour rating, this pack will not provide the correct run-time or charging profile. Confirm the required capacity and voltage before ordering.

Questions about this item

How do I install the Estry 431036 battery and which polarity step is often missed?

Match the 3.6V 600mAh pack's terminals to the device's + and - contacts; the 42.64 x 30.0 x 14.45 mm size fits the original compartment, but reversing polarity damages the protection circuit.

What maintenance or replacement will the 3.6V 600mAh Ni-MH pack need over time?

Expect gradual capacity loss after several hundred charge cycles; store at about 40 % charge in a cool place and replace when runtime drops below useful levels.

What limit appears first during sustained use of this 2.16 Wh battery?

The 600 mAh capacity sets runtime; continuous high drain triggers the built-in over-discharge and short-circuit protection, cutting output until the pack cools.
