The 123A 3.7V Rechargeable Lithium-ion (Li-ion) Battery is a high-capacity power solution designed for high-drain electronic devices. Unlike standard primary (non-rechargeable) lithium batteries, these rechargeable cells provide a sustainable and cost-effective alternative for frequent users.
With a stable 3.7V output and a 1300mAh capacity, this battery is engineered to deliver long-lasting, consistent power to precision equipment, ranging from professional tactical flashlights to modern digital smart home security sensors.
High Energy Density: The 1300mAh rating ensures extended runtime for power-hungry devices, reducing the frequency of recharges.
Rechargeable Chemistry: Advanced Li-ion technology allows for hundreds of charge/discharge cycles, significantly lowering long-term operating costs compared to disposable batteries.
Stable 3.7V Output: Provides higher nominal voltage than standard 3V primary cells, which can improve the performance and brightness of LED flashlights.
Multi-Device Compatibility: Designed as a rechargeable equivalent to CR123A, RCR123A, and 16340 battery sizes.
Built-in Protection: Typically features internal safety circuitry to prevent over-charging, over-discharging, and short-circuiting.
Chemistry: Lithium-ion (Li-ion).
Nominal Voltage: 3.7V.
Capacity: 1300mAh.
Tactical Gear: High-lumen LED flashlights and laser sights.
Smart Home Security: Wireless security cameras, motion sensors, and smart door locks.
Photography: Digital cameras, external flash units, and light meters.
Electronics: Portable handheld devices and small medical equipment.
Can I use this in place of a standard 3V CR123A battery? Check your device’s manual first. While the size is the same, this battery is 3.7V, whereas standard disposables are 3V. Some sensitive devices may not be rated for the higher voltage of rechargeable cells.
Does it require a special charger? Yes. You must use a dedicated Li-ion smart charger. Using a standard Ni-MH or Ni-Cd charger can damage the battery or create a safety hazard.
How long does the charge last? This depends entirely on the device. In a high-drain flashlight, it may last several hours of continuous use; in a low-power security sensor, it can last several months between charges.
