Direct replacement for AT&T cordless handsets

The Estry CL84250 is a nickel-metal hydride battery pack rated at 2.4 volts and 700 milliampere-hours, delivering 1.68 watt-hours. It matches the original dimensions of 44.6 by 20.91 by 10.47 millimetres and weighs 49.5 grams. The pack fits models such as CL84250, EL52510, TL91270 and many others listed in the compatibility data. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Steady output during long talk time

Nickel-metal hydride chemistry provides a stable voltage curve throughout extended calls rather than a sharp drop after a brief burst. The built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuits, preserving capacity over repeated daily cycles. One-year battery-pack warranty reflects the supplier's confidence in sustained performance.

Upgrades worn-out packs in listed handsets

This cell replaces the original BT266342, BT183342, BT166342 and BT283342 part numbers when they no longer hold a charge. The jump is worth it if your handset shows reduced talk time, frequent low-battery alerts or cannot complete a full day on standby. Buyers who need a different voltage, higher capacity or a lithium chemistry should look elsewhere.

Questions about this item

Does the 2.4 V 700 mAh Ni-MH pack generate noticeable heat when the phone stays on its base all day?

Ni-MH chemistry runs cool during normal standby charging; the 1.68 Wh cell produces minimal warmth even after continuous trickle charge.

What must I already own for this battery to work?

You need a compatible AT&T or VTech cordless handset such as the CL84250, EL52510 or TL91270 that accepts the BT266342 form factor.

Will this 44.6 × 20.91 × 10.47 mm pack fit the older CL80101 handset I still use?

Yes, the dimensions and 2.4 V rating match the original BT183342 cell used in the CL80101, so it drops straight in.
