Description

The Duracell Ultra CR123 is a 3V lithium battery built for high-drain devices that demand consistent power under sustained use. The lithium cell chemistry delivers higher energy density than alkaline equivalents, making it the standard choice for digital cameras, tactical torches, CCTV motion sensors, smart home security keypads and medical monitoring equipment where frequent battery replacement is impractical.

Designed to perform across extreme temperature ranges from -40°C to +60°C, the CR123 maintains stable voltage output in outdoor security cameras during winter and in car boot-mounted equipment during summer. The battery is also sold under the DL123A designation by Duracell and is cross-compatible with CR17345 and other CR123A-sized cells from different manufacturers. The single-pack format suits users replacing one cell at a time in rotation or testing compatibility before committing to multi-packs.

The cell measures 17mm diameter by 34.5mm length and weighs 17g, making it significantly lighter than comparable alkaline formats while delivering higher capacity. Duracell rates the Ultra CR123 at approximately 1,550mAh capacity, though real-world runtime depends on the device's current draw. The battery carries a 10-year storage shelf life when kept at room temperature, allowing stockpiling for emergency kits and infrequently-used equipment.

Frequently Asked

Is the CR123 rechargeable?

No. The Duracell Ultra CR123 is a single-use lithium primary cell and cannot be recharged. Attempting to recharge it may cause leakage or rupture. Rechargeable alternatives use RCR123A or 16340 designations and require a dedicated lithium-ion charger.

What devices use CR123 batteries?

Common applications include digital cameras (particularly older Canon and Nikon models), LED torches, wireless CCTV cameras, smart home door locks, motion sensors, laser sights and medical glucose monitors. Check your device manual for the exact cell size required.

Can I use two CR123 cells in series?

Yes, when a device specifies 6V power. Two CR123 cells in series deliver 6V combined, commonly used in high-output torches and some camera flash units. Ensure both cells are from the same batch and have equal charge to prevent unbalanced discharge.

How long does a CR123 last in storage?

Duracell rates the Ultra CR123 with a 10-year shelf life when stored at room temperature in the original packaging. Extreme heat shortens shelf life, so avoid storing in direct sunlight or hot vehicle glove boxes.

Shipping & Returns

Free worldwide delivery

Free worldwide delivery on all orders over £99. International orders for third-party brand products may be subject to an additional courier surcharge based on volumetric weight, particularly on larger lighting fixtures — if a surcharge applies, our team will email you with the amount before dispatch and you can proceed or cancel for a full refund.
