Snap-in installation with no soldering

The pack uses the original connector and form factor, so it drops into the handset battery compartment without tools or wiring changes. The only common issue is ordering the wrong variant; verify the exact model or part number printed on your old cell before purchase.

Steady 4.32 Wh output over long talk time

Questions about this item

How can I verify the Estry 39880 battery is working correctly after installation?

After fitting the battery, the handset should power on and hold a charge through several call cycles; the built-in overcharge, over-discharge, over-voltage and short-circuit protection will activate automatically if any limit is exceeded.

What comes in the box with the Estry 39880 and is anything else required?

The package contains the 3.6 V 1200 mAh Ni-MH battery pack measuring 50.43 x 42.54 x 14.4 mm and weighing 90.3 g; no additional cables or chargers are included, so the existing handset cradle is used for charging.

Which capacity version of the Estry 39880 should I choose for my Northwestern Bell handset?

This model is offered only as a 1200 mAh 3.6 V pack rated at 4.32 Wh, so select this single version when your handset appears on the compatible list such as 39880, 39625 or 36248.
