The Nitecore NL1823 (NL183) is rated at 2300mAh at a nominal 3.7V, for 8.5Wh of stored energy. That capacity is well matched to everyday EDC and tactical flashlights that run on a single 18650 cell.
Is the Nitecore NL1823 (NL183) a protected 18650 battery?
Yes. The Nitecore NL1823 (NL183) has an integrated PCB protection circuit that prevents over-charging and over-discharging, which is why it is safe to use in the majority of 18650-compatible flashlights and devices that call for a protected cell.
How many times can you recharge the Nitecore NL1823 (NL183)?
