Duracell CR123A 3V Lithium Batteries - 2 Pack

The Duracell CR123A is a 3V cylindrical lithium battery supplied as a 2-pack, designed for high-drain devices that need reliable power over extended periods. Each cell measures 34.5mm in length and 17mm in diameter, fitting equipment that specifies CR123A, CR123, DL123A or EL123AP battery types.

These batteries are most commonly used in wireless security cameras, motion sensors, high-output LED torches, rangefinders and digital cameras with flash units. The lithium chemistry provides consistent voltage throughout the discharge cycle, preventing the gradual dimming or performance drop that alkaline batteries show as they deplete. This makes CR123A cells particularly suited to equipment where sudden power loss would cause missed events or failed captures.

Duracell rates these cells with a 10-year shelf life when stored at room temperature, making them practical for emergency kits, seasonal equipment and backup supplies. The lithium construction also performs reliably in temperatures from -40°C to +60°C, covering outdoor security installations in winter and attic-mounted equipment in summer. Each cell weighs 16g and delivers approximately 1,500mAh capacity at typical drain rates.

What devices use CR123A batteries?

CR123A cells are standard in wireless security cameras (Ring, Arlo, Blink models), high-output torches, laser rangefinders, film cameras with motorised advance, and some smoke detectors. Check your device manual for the exact battery code required — CR123A is also sold as DL123A or EL123AP depending on manufacturer.

Are these rechargeable?

No. Duracell CR123A cells are single-use lithium primaries. Attempting to recharge them can cause leakage or rupture. Rechargeable equivalents are sold as RCR123 or 16340 Li-ion cells, but they deliver 3.7V instead of 3V and are not compatible with all CR123A devices.

How long do they last in a security camera?

Battery life depends on recording frequency, temperature and WiFi signal strength. In a typical wireless camera recording 10-20 events per day, a pair of CR123A cells lasts 2-4 months. Cameras in constant live-view mode or extreme cold drain faster.

Can they be stored long-term?

Yes. Duracell rates these with a 10-year shelf life when kept at room temperature in the original packaging. Store them away from metal objects that could short the terminals, and check the expiry date printed on each cell before use.
