DULEX 12-Pack 3.7V 800mAH CR123A Rechargeable Batteries - Long Lasting

In this review the DULEX 12-Pack CR123A rechargeable batteries are evaluated for people who rely on battery-powered security cameras and flashlights. The bottom line: these cells are tailored for repeated use in Arlo-compatible cameras and devices that need a steady, safe power source, and they stand out for built-in safety circuitry and a claimed longer runtime. The reviewer found them particularly appropriate where charger safety and moderate high-capacity performance matter, though measured capacity can vary and initial charging is required before use.

Key Features

• High capacity: The 3.7V 800mAh rating provides stronger run time than many single-use alternatives for compatible Arlo cameras and LED flashlights.
• Built-in safety: Each battery includes integrated fault and heat protection to reduce risk during long-term use and in varied environments.
• Charger fail-safe: The supplied charging system claims over-charge and overheating prevention to protect both batteries and devices.
• Wide compatibility: Designed to work with Arlo VMS3130, VMC3030, 3200, 3330, 3430 and 3530 cameras as well as other CR123A devices.
• Durability in temperature extremes: Rated to perform from about -4 degree to 45 degree, which helps maintain operation in seasonal outdoor camera use.
• Backed warranty: Each order is covered by a one-year warranty that simplifies replacement if there are quality issues.

Who It's For

This pack is best for homeowners and small business owners who use Arlo HD security cameras or high-draw LED flashlights and want rechargeable cells with safety features. It suits anyone who values built-in protection against over-charge and short-circuit risks and needs multiple spare cells for routine swaps.

Those who should look elsewhere include users who require factory-verified capacity above 800mAh for extended deployment without recharging, or those who prefer single-use CR123A cells for occasional, long-term storage; the product requires initial charging and is not intended to replace one-time-use batteries directly.

Pros & Cons

Pros

• Good build quality with integrated protection circuits for safer repeated charging and use.
• Clear compatibility with a range of Arlo camera models and common CR123A devices.
• Convenient 12-pack size reduces frequency of purchases and supports multiple camera setups.
• One-year warranty adds reassurance after purchase.

Cons

• Measured capacity can be lower than labeled in some tests, so actual runtime for cameras may vary between users.
• Not suitable for charging disposable CR123A brands; must be charged before first use.

Specifications

Our Verdict
