Panasonic BR-2/3A 1.2 Ah Lithium Standard Battery

Purpose-built power for critical electronics

The Panasonic BR-2/3A is a primary lithium battery rated at 1.2 Ah and 3 volts. It is manufactured for equipment that demands reliable energy over long periods, such as security alarms, emergency beacons, dive computers and memory-backup circuits. The chemistry provides a stable voltage profile suited to low-drain and pulse-load applications.

Suits fixed or portable gear needing years

This cell fits devices designed around the 2/3 A form factor and 3 V lithium chemistry. It is not intended for rechargeable use, so equipment requiring secondary cells or a different voltage should use an alternative power source. Buyers who need a rechargeable pack or a higher capacity in the same footprint must look elsewhere.

Steady output through extended deployments

The lithium chemistry maintains consistent voltage during the prolonged, low-current draws typical of metering and backup duties. It also supports the intermittent high pulses required by radio transmitters and night-vision gear without significant voltage sag. Performance remains predictable across the wide temperature ranges encountered in industrial and outdoor environments.
