Energizer 123 Lithium Battery (CR123A) – Reliable power for high-tech devices

The Energizer CR123A (Model CR123A-B1) is a powerful 3V lithium battery that has been specially developed for devices with high energy requirements. Whether in professional photography, for tactical equipment or in modern security systems – this battery provides constant power under the most extreme conditions.

The “B1” in the model designation usually stands for the packaging unit (Blister 1), i.e. a single battery per pack. Thanks to lithium technology, it offers a significantly higher energy density and longer shelf life than conventional alkaline batteries.

Highlights at a glance

• Extreme shelf life: With a shelf life of up to 10 years it is the ideal backup battery for emergency equipment and long-term projects.
• Temperature resistant: Works reliably in an extreme range of -40°C to +60°C, making it perfect for outdoor use in any weather.
• Constant voltage: Maintains a stable output voltage of 3V over almost the entire discharge period, which is especially important for sensitive electronics.
• Leak protection: The advanced construction effectively protects your expensive devices from damage caused by leaking battery acid.
• Low weight: At only around 17 grams, it is considerably lighter than comparable energy storage devices, ideal for portable equipment.

Typical areas of application

The CR123A is a versatile standard for specialised electronics:

• Photography & Video
  • Digital cameras, flash units and light meters benefit from the fast charging cycles and high pulse load capacity.
• Security technology
  • Wireless alarm systems, motion detectors and smart home sensors utilise the long service life for infrequent maintenance intervals.
• Tactical equipment
  • High-performance torches (tactical flashlights), laser aiming devices and night vision devices rely on constant brightness.
• Medical devices
  • Portable diagnostic devices and monitors require the absolute reliability of the lithium cell.

FAQs on the Energizer CR123A

Is the Energizer CR123A rechargeable?

No. This is a primary battery (single use). Never attempt to recharge this battery as this may result in leakage or explosion. For rechargeable variants, you must search for “RCR123A” or “16340” batteries.

Is this battery suitable as a replacement for DL123A or EL123AP?

Yes. CR123A is the standard designation. Designations such as DL123A (Duracell), EL123AP (Energizer Photo) or CR17345 refer to the same battery type and are fully compatible with each other.
