Replacement for Radio Shack handsets

This Estry 43-9025 Ni-MH pack delivers 3.6V and 850mAh to restore talk time on cordless phones that used the original 43-9025, 43-9026, 43-9031, 43-9030, 23-968 or 43-9024 cells. It is built to the same electrical specification as the factory battery and carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for safety compliance.

Simple two-wire swap with polarity check

Installation requires opening the handset battery compartment, disconnecting the old pack and connecting the new one using the existing connector or solder pads; the 54.16 x 31.92 x 11.17mm footprint matches the original cavity. The only common issue is reversed polarity — verify the red and black leads against the handset markings before sealing the case to avoid damage.

Ideal for owners of listed Radio Shack models

This pack suits users who need a direct 3.06Wh replacement for the exact part numbers shown above and want certified overcharge, over-discharge, over-voltage and short-circuit protection. Buyers whose handset uses a different voltage, connector layout or form factor should look at other options.
