How to choose the right CR2 battery

Before ordering, check the marking printed on your old battery or in the device manual. Compatible markings may include CR2, CR 2, CR-2 and CR15H270. The key specification is 3V lithium; CR2 cells are non-rechargeable primary batteries unless the device specifically states a rechargeable alternative is supported.

Brand choice is also important. Duracell CR2, Energizer CR2, Varta CR2 and Panasonic CR2 lithium batteries are known for consistent output and long storage life. For equipment such as alarms, cameras or sensors, using a quality cell helps reduce the risk of sudden power loss and supports stable device operation.
