The Nitecore NL1836R is a protected 18650 lithium-ion battery with a 3600 mAh capacity, compatible with almost any flashlight—including other brands—even models requiring longer protected cells.
Featuring a button-top terminal and a built-in USB-C smart charging circuit, it allows direct charging without an external charger (though it can still be charged in a standard charger). A red indicator light shows ongoing charging, while a green light signals a full charge. It is fully protected against overcharging, over-discharging, and short-circuiting, supporting up to 6A continuous discharge with a 500+ cycle lifespan.
