Energizer 2CR5 6V Lithium Battery - Single Pack

The Energizer 2CR5 is a 6V lithium battery designed for high-drain devices including professional cameras, security equipment, electronic dog collars and medical instruments. The lithium chemistry provides stable voltage output across the battery's discharge cycle, maintaining consistent performance until the cell is depleted rather than gradually fading like alkaline alternatives.

Built for devices that demand reliable power in intermittent or continuous-draw applications, the 2CR5 handles cold weather operation better than most battery chemistries and maintains function in temperatures from -40°C to 60°C. The 10-year shelf life makes it suitable for emergency kits, backup power stores, and devices that sit unused for months between deployment. The single-cell format packs the equivalent of two CR123A batteries into one integrated unit, simplifying installation in compatible devices.

Each battery weighs 40g and measures 45mm x 34mm x 17mm, fitting the 2CR5 form factor used in older digital cameras, some film cameras, certain wireless security sensors, and specialist medical equipment. The lithium construction is lighter than equivalent alkaline packs and less prone to leakage during storage, reducing the risk of device damage from expired cells left in a camera bag or sensor housing.

What devices use the 2CR5 battery?

The 2CR5 is found in older digital cameras (particularly Canon and Nikon models from the 1990s-2000s), film cameras, electronic dog collars, security sensors, and some medical instruments. Check your device manual or the battery compartment label to confirm compatibility before ordering.

Can this battery be recharged?

No. The Energizer 2CR5 is a primary lithium cell and cannot be recharged. Attempting to recharge it may cause leakage, overheating or rupture. Dispose of used batteries according to local battery recycling guidelines.

How long does the 10-year shelf life last in actual use?

The 10-year shelf life refers to storage, not active use. In-device runtime depends on the draw characteristics of your equipment. High-drain devices like cameras may exhaust the battery in weeks of regular use, while low-drain sensors may run for months.

Is this the same as two CR123A batteries?

Electrically similar but physically different. The 2CR5 delivers 6V like two CR123A cells in series, but the 2CR5 is a single integrated unit that will not fit devices designed for separate CR123A cells. The two formats are not interchangeable.
