Direct replacement battery

The Estry J2458 is a 3.6V 700mAh Ni-MH pack built to the original specifications for cordless phones and similar devices. It delivers 2.52Wh of energy in a 45.6 x 31.3 x 10.6mm form factor weighing 61.0g.

Upgrade from depleted cells

The pack replaces J2458 J2457 M6163 TEL10160 part numbers when the original cells no longer hold a charge. The jump is worth it when talk time has dropped noticeably or the handset warns of low battery after a short period.

Simple two-wire install

Installation typically means opening the battery compartment, unplugging the old connector and fitting the new pack in the same orientation. The most common issue is reversed polarity on the connector pins, so match the wire colours before you press the plug home.

Questions about this item

Will the 45.6 x 31.3 x 10.6 mm dimensions fit my existing battery compartment?

The pack measures 45.6 mm long, 31.3 mm wide and 10.6 mm thick; compare those figures with your device's battery bay before ordering.

What is the correct way to insert the J2458 pack and what mistake should I avoid?

Match the connector polarity exactly as the original J2458, J2457, M6163 or TEL10160 cell; reversing the leads triggers the short-circuit protection and prevents charging.

When should I expect to replace this 700 mAh Ni-MH cell?

Typical service life is one to two years; replace when talk time drops noticeably or the handset no longer holds a full 3.6 V charge.
