Tenergy 1300mAH CR123A Lithium Battery Review

The right spare battery begins with the exact markings inside the device. The Tenergy 1300mAH CR123A Lithium Battery is a CR123A lithium cell, a format used in some flashlights and photographic equipment rather than ordinary AA gear.

CR123A and Rechargeable Lookalikes Aren't the Same

Tenergy identifies its standard 3V CR123A lithium products as non-rechargeable primary cells. I'd follow the package marking for the exact battery and never put a primary cell into a charger. A similarly shaped rechargeable alternative can have a different voltage and may be unsuitable for the equipment.

• Format: CR123A.
• Listed product capacity: 1,300mAh in this catalog title.
• Role: Replacement cell for compatible devices.
• Charging: Treat standard primary CR123A cells as non-rechargeable.

Buy for the Device, Not the Capacity Label

Confirm the supported voltage, chemistry, and number of cells in the equipment manual. Capacity ratings are measured under particular conditions, so the largest mAh number isn't the only comparison. Shelf age, authenticity, and a reliable supply source are practical considerations too.

I'd keep replacements protected from loose metal objects and follow the manufacturer's instructions about matching cells. If a device uses more than one battery, a mixed collection of different ages and types is a poor starting point.

Spare-Cell Planning

A flashlight using CR123A needs that format in the spare box. Keeping only familiar household batteries won't help. Mark the storage location and check the package date and storage guidance rather than assuming every lithium cell can sit indefinitely without attention.

I haven't tested this cell's capacity. The assessment is about choosing the correct replacement and avoiding confusion with rechargeable formats. I'd buy it for a device explicitly calling for the exact CR123A specification, not as a generic battery that happens to fit.
