Direct replacement for Panasonic cordless phones

The Estry KX-T3610 is a 3.6V 600mAh nickel-metal hydride battery pack built to match the original dimensions of 42.64 x 30.0 x 14.45 mm and a weight of 63.3 g. It fits a wide range of Panasonic models including KX-T3610, KX-T4342, KX-TC150, KX-T3800, KX-TC424, KX-T39102, KX-T4600, KX-T4360, KX-T3860, KX-T3930, KX-TC160, KX-T4350, 3807, KX-T4370 and KX-TCM440. It also replaces part numbers HHR-P301, P-P301, TYPE 2 and KX-A36A.

Steady capacity over repeated cycles

The 2.16 Wh cell delivers consistent voltage during long talk and standby periods thanks to built-in overcharge, over-discharge, over-voltage and short-circuit protection. Ni-MH chemistry avoids memory effect so the pack holds its rated capacity across hundreds of charge cycles without the sudden voltage drops seen in older chemistries. ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm the safety and environmental compliance of every unit.

Simple drop-in install with polarity check

The pack slides into the handset battery compartment exactly like the original; no soldering or tools are required. The only common issue is reversed polarity if the connector is forced in the wrong orientation, so align the keyed plug before pressing firmly. Buyers who need a higher-capacity pack or a different voltage will not be served by this 3.6V 600mAh model.
