Replacement battery for cordless phones

The Estry E65 is a 6.0V 2100mAh nickel-metal hydride pack built to match the original dimensions and electrical ratings of the listed handsets. It fits models such as the E65, H680, ES40 and the BP-714 series part numbers. The pack delivers 12.6Wh and includes overcharge, over-discharge, over-voltage and short-circuit protection. Buyers seeking a direct drop-in replacement for these specific devices will find the correct fit.

Limits of Ni-MH chemistry and connector fit

Nickel-metal hydride cells self-discharge faster than lithium types and perform best when cycled regularly rather than left on constant trickle charge. The pack uses the original connector layout so no adapter is required, but the keyed plug will only seat one way. Capacity will gradually decline after several hundred full cycles and the battery is not suited for high-drain applications beyond the rated 2100mAh. The physical envelope of 92.38 x 46.96 x 22.85mm must match the handset compartment exactly.

Check model and part number before ordering

Verify that your handset model appears in the compatible list such as E65, UC3000, ES520 or EX1 and that the original battery part number matches one of the BP codes like BP-711, BP-E77K or BP-818. Confirm the voltage printed on the old pack reads 6.0V and that the connector polarity aligns with the replacement. The pack weighs 193.5g so ensure the handset battery door closes without strain. Do not purchase if your device uses a different voltage or connector style.
