Quick verdict
Energizer CR123A in a 12-pack is the best all-around recommendation for most Arlo users - it balances runtime, cold-weather performance, and per-cell cost better than any competitor. Upgrade to SureFire if your cameras face genuinely extreme temperatures. Use Amazon Basics if you're running a large multi-camera system on a budget and buying from Amazon directly.

Energizer CR123A Lithium - Best Overall
Energizer's CR123A is one of the most widely recommended cells specifically for Arlo cameras across owner communities and tech review sites. The 12-pack format brings per-cell cost down to a level where replacing a full four-camera setup doesn't feel painful. Energizer's lithium cells maintain stable voltage down to -40°C, which matters for outdoor cameras in winter climates. The 10-year shelf life means you can stock up and not worry about stored cells losing charge. Multiple Arlo user communities cite Energizer as the brand with the most consistent reported runtimes across camera generations.

Energizer CR123A Lithium - Best Overall
Energizer's CR123A is one of the most widely recommended cells specifically for Arlo cameras across owner communities and tech review sites. The 12-pack format brings per-cell cost down to a level where replacing a full four-camera setup doesn't feel painful. Energizer's lithium cells maintain stable voltage down to -40°C, which matters for outdoor cameras in winter climates. The 10-year shelf life means you can stock up and not worry about stored cells losing charge. Multiple Arlo user communities cite Energizer as the brand with the most consistent reported runtimes across camera generations.
Duracell High Power Lithium CR123A - Best Premium Pick
Duracell's CR123A High Power cells are built to the same tight tolerances as their specialty lithium line. The voltage curve stays flat longer than cheaper alternatives, which Arlo's power management translates into more days before the low-battery alert appears. Duracell is one of the few brands that reliably replaces cells that fail prematurely under warranty, which is useful when you have expensive surveillance equipment depending on them. The 4- and 6-pack formats cost more per cell than 12-packs, so buy the largest pack size you can find for the best value.
Panasonic CR123A - Best Consistent Performer
Panasonic manufactures CR123A cells for many OEM customers and their retail line applies the same production standards. The Japanese manufacturing origin is a meaningful quality differentiator in this category where counterfeiting and substandard cells are common. Panasonic's 12-pack is competitively priced and consistently tests well for capacity and voltage stability. For users who want manufacturer confidence without paying the SureFire premium, Panasonic is the most reliable mid-tier choice.
SureFire CR123A - Best for Extreme Cold
SureFire CR123A batteries are rated to an extended upper limit of 71°C and are built for harsh environments including law enforcement and military use. For Arlo cameras mounted in desert climates with extreme summer heat, or in very cold northern winters, SureFire's tolerance margins provide a meaningful buffer that standard cells don't. They also have the longest track record of any brand in the CR123A category since they helped popularize the format through their flashlight products. The per-cell cost is the highest in this category, so they're best reserved for cameras in genuinely extreme environments or as a backup reliability option.
Amazon Basics CR123A - Best Budget Bulk
Amazon's house-brand CR123A cells are manufactured to a reasonable standard and offer the lowest per-cell price among the options here. The 12-pack format is the right buy, and many Arlo owners with multiple cameras choose these for cost efficiency when running 8+ cells across a system. Performance is slightly below Energizer or Panasonic in real-world runtime, but the price difference often justifies the trade-off. Buy only from Amazon directly to avoid the counterfeit problem that affects CR123A generics sold through third-party sellers.
What matters most
Lithium chemistry is mandatory
Arlo cameras are designed for lithium CR123A cells. Alkaline cells, if even available in this format, will fail faster in cold and drain unevenly. Always buy lithium.
Temperature rating matters for outdoor use
Standard lithium cells are rated to -40°C, which handles most climates. If your camera location sees extreme heat above 50°C, check for an extended upper-temp rating.
Buy in packs of 12 or more
CR123A is expensive per cell at small quantities. For multi-camera Arlo systems, a 12-pack or larger dramatically reduces per-cell cost. Stock a spare set so you're not waiting for shipping when a camera dies.
Avoid third-party marketplace sellers for this format
CR123A counterfeiting is a documented problem. Buy from the brand's own Amazon storefront or a recognized major retailer to ensure genuine cells.

Frequently asked
Runtime depends heavily on motion activity, video quality settings, and temperature. Under typical suburban conditions with moderate motion triggering, quality lithium CR123A batteries last 4-6 months in Arlo Pro and Essential models. In high-traffic locations or during winter, expect 2-3 months. Arlo's app shows battery percentage, so tracking your personal drain rate over the first cycle gives the most accurate expectation.
Arlo officially recommends non-rechargeable lithium CR123A cells and does not support rechargeable CR123 batteries (which output 3.7V instead of 3V). Using 3.7V RCR123 cells can damage Arlo cameras. Arlo Pro 3 and later models have a built-in rechargeable battery pack that charges via USB-C - those models do not use disposable CR123A cells at all.
Bulk no-name CR123A cells carry real risk for Arlo cameras. Low-quality cells can leak, deliver inconsistent voltage, or fail to trigger the camera reliably in cold weather. Counterfeiting is also a known problem with CR123A on major marketplaces. Stick to well-known brands like Duracell, Energizer, Panasonic, or SureFire and buy from first-party sellers or verified sources.
