Replacement battery for AT&T cordless phones

This 700mAh 2.4V cell replaces the original AT&T BT166342 and related part numbers used in numerous CL, EL, TL and CRL series handsets. It supplies 1.68Wh of capacity and weighs 24.5g. The new fully decoded chip works like the original battery.

Check your handset model and original part number

Verify that your device appears in the compatibility list which includes models such as CL82100, EL51100, TL92270 and many others. Match the part number on your old battery to BT166342, BT183342, BT266342 or BT283342 before ordering. The battery measures 44.60 x 20.91 x 10.47mm so confirm the compartment can accept those dimensions.

Fits directly into the handset battery bay

No extra wiring or adapters are required; the pack slots into the existing compartment and connects with the original contacts. Built-in overcharge, over-discharge, over-voltage and short-circuit protection helps preserve battery life. Allow two to three full charge cycles for the cell to reach its best performance.
