LG M29 18650 Battery, 2850mAh, 10A

LG M29 18650 Rechargeable Battery – Reliable Power for Flashlights and Devices

The LG M29 is an 18650-format rechargeable battery with a rated capacity of 2850 mAh and a maximum discharge current of 10A. It is suitable for flashlights, headlamps, and other devices that require a stable and powerful power source.

The battery has a flat positive terminal, making it compatible with devices designed for unprotected batteries. Before use, make sure the dimensions match those of your device's original battery.

Unprotected battery—what does that mean?

Batteries without a protection circuit have standard dimensions and can deliver a higher discharge current. They are suitable for devices designed for the standard 18650 format, such as Zebralight and Dulotec flashlights.

Protected batteries contain an additional circuit board that protects against overcharging, over-discharging, and excessive current. They are slightly longer and wider than standard batteries and are not suitable for all flashlights. They are compatible with brands such as Acebeam, Olight, Fenix, Nitecore, Armytec, and others that feature mechanical reverse-insertion protection.

If you're not sure which battery you need, measure the size of the original battery in mm and compare it to the technical specifications. You can also contact the Dulotec.COM team for assistance.
