Replacement Ni-MH handset battery

This 2.4V 550mAh Ni-MH pack replaces original batteries in compatible AT&T Clarity GE RCA and Vtech cordless telephones. It matches the voltage and capacity specified for the listed handset models. The battery is supplied new and ready for installation.

Upgrade from depleted original cells

It substitutes for part numbers BT8001 BT8000 BT8300 BT18433 BT28433 BT184342 BT284342 89-1335-00 89-1344-01 BATT-6010 CPH-515D and Clarity D613B. The jump is worthwhile when talk time has fallen or the handset no longer holds a charge through a normal day.

Capacity and headroom

The 550mAh rating supports typical DECT 6.0 standby and talk cycles for the listed CL EL SL TL and SB series handsets. Runtime will shorten if the handset transmitter runs at high power or if the battery ages beyond its normal cycle life.
