High-capacity NiMH handset battery

The Uniden BT-1021 is a 600 mAh nickel-metal hydride rechargeable battery rated at 2.4 V DC in AAA size. It replaces original batteries such as BT-1016, BT-1008, BT-1025 and CPH-515B. The cell is designed for owners of compatible Uniden DECT cordless handsets who need longer talk time between charges. It fits a wide range of models across the D1361, D1660, D1780, DECT2080 and related series.

Steady discharge for long calls

Nickel-metal hydride chemistry delivers a stable voltage curve during extended conversations rather than a brief peak followed by rapid drop-off. The 600 mAh capacity supports roughly double the talk duration of lower-rated packs under the same load. Self-discharge is low enough that a handset left on its base for days remains ready for use. No memory effect means the battery can be topped up at any time without capacity loss.

Simple AAA swap with polarity care

Installation requires opening the handset battery compartment and inserting the AAA cell with correct polarity orientation. The most common issue is reversed insertion, which prevents charging and can damage the handset circuitry. Contacts should be clean and free of corrosion before fitting the new cell. After installation, place the handset on its base for a full initial charge cycle before regular use.
