Direct Replacement for Panasonic KX-T Systems

This nickel-metal hydride cell delivers 2.4 volts and 300 milliampere-hours in the exact form factor required by the KX-T61610B, KX-T30810, KX-T123210B and related PBX control units. It matches the original P-01H-F2G1 part number so installers can swap the backup power source without rewiring or firmware changes.

Low Self-Discharge Chemistry with Protection Circuit

The pack includes over-charge, over-discharge, over-voltage and short-circuit safeguards that keep the 0.72 watt-hour capacity stable during long float service. RoHS, CE, ISO 9001 and UN 38.3 certifications confirm the cells meet transport and substance restrictions for commercial deployments.

Questions about this item

How do I install the Estry KX-T61610B battery and which step do people often get wrong?

Open the handset compartment, match the 2.4V polarity markings, insert the 28.47 x 17.22 x 14.28mm pack, and close the cover. The common mistake is reversing the connector orientation, which prevents charging.

What maintenance or replacement will the 300mAh Ni-MH pack need later?

The pack is rated for one year of service. After that period, capacity drops and talk time shortens, so a fresh 0.72Wh replacement restores original runtime.

What limit appears first when the battery is used continuously on a call?

The 300mAh capacity governs talk time; once the 2.4V output falls below the handset threshold, the call drops and the pack must be recharged.
