2CR5, 5032LC, EL2CR5, DL245 Batteries - Dimensions, Equivalents, and Replacements

2CR5 is a very popular non-rechargeable, lithium 6 volts, the rectangular battery often used in digital cameras, photographic equipment, emergency lights, LED flashlights, medical equipment, military equipment, home security systems, and similar.

Thanks to its shape, 2CR5 can be inserted in the battery compartment only one way, allowing the users to change the battery quickly even in low-light conditions, without worrying about its orientation.

2CR5 Battery Features and Specifications

2CR5 battery features physical dimensions of (H x L x W) 45 x 37 x 17 mm, the nominal voltage of 6 volts, and the capacity in the 1300-1500 mAh range.

Internally, 2CR5 battery consists of two non-rechargeable 3V lithium batteries connected in series.

2CR5 is a very popular battery often having other labels as well, including 5032LC, EL2CR5, DL245, RL2CR5, KL2CR5, etc.

Such a long list of labels may lead to confusion, but practically all manufacturers also use its 'standard' label - '2CR5' battery.

Thanks to the lithium non-rechargeable chemistry, 2CR5 battery often has a shelf/standby life of 10+ years, making this battery very popular choice for standby applications where the battery may wait for years before being used for the very first time - but it must operate reliably at the moment notice.

2CR5 vs CR123A Batteries

CR123A battery is a lithium battery with physical dimensions of (diameter x height) of 34 x 17 mm and practically, it is half of the 2CR5 battery, just a little bit shorter.

Some devices feature a battery compartment that accepts one 2CR5 battery or two CR123A batteries (side-by-side) without any issues, while some devices feature a plastic battery holder/adapter.

In most situations two CR123A batteries may replace one 2CR5 battery, if it is explicitly stated by the device manufacturer - the main issues are 3 mm height difference between these batteries and the fact that CR123A battery may be found as non-rechargeable 3V battery and rechargeable 3.6-3.7V battery.

A pair of rechargeable CR123A (RCR123A) batteries feature a nominal voltage of 7.2-7.4 volts and this 1.2-1.4 volts difference may cause the device to malfunction or it can even damage/destroy the device - for short, use CR123A/RCR123A batteries only if/as recommended by the device manufacturer!

Long Story Short: If you are looking for a 2CR5 battery replacement, always go for the batteries from reputable brands. Such batteries feature very long shelf/standby period, ensuring reliable operation.

While 2CR5 may be, in theory, replaced by a pair of CR123A batteries, that should be done only if explicitly permitted by the device manufacturer!
