What to look for
Lithium vs. alkaline
Always choose lithium for CR123A applications. Alkaline 3V cells in this format are rare and underperform significantly. Lithium cells handle temperature extremes, hold voltage longer, and last years on the shelf.
Shelf life
Look for cells with a 10-year shelf date stamped on the packaging. This is standard for Panasonic, Energizer, and SureFire. Shorter dates (5-7 years) are common with off-brand cells and signal lower quality raw materials.
Pack size economics
CR123A cells are rarely cheap individually. Buying 12-packs or larger brings the per-cell cost down significantly. If you run multiple cameras or flashlights, buy in bulk.
Temperature rating
If you live in a cold climate or use devices outdoors in winter, check the operating temperature spec. Premium lithium cells maintain output well below freezing; cheaper cells lose voltage noticeably at low temperatures.

FAQs
CR123A batteries power a wide range of devices including wireless security cameras (Arlo, Ring), tactical and everyday-carry flashlights, gun-mounted lights, smoke detectors, medical devices, and some older film cameras. Their compact size and 3V output make them versatile across both consumer and professional applications.
Premium lithium CR123A batteries from brands like Panasonic and Energizer carry a 10-year shelf life. This makes them ideal for emergency kits, smoke detectors, and backup supplies where batteries sit unused for years before being needed.
Yes. Arlo cameras accept any standard CR123A battery. Arlo sells their own branded cells, but third-party options from Panasonic, Energizer, and Duracell work just as well and often cost less per cell when purchased in bulk packs.
