Nitecore 2300mAh, NL1823, 18650 Battery

The NiteCore 2300 mAh NL1823 (18650) protected lithium-ion rechargeable battery will allow you to get incredible runtime out of the flashlights that are designed to use the 18650 battery. The battery package is roughly the same size as two CR123A batteries and can reduce operating cost as compared to disposable batteries. A protection circuit is attached to the battery, specifically designed for use in high-drain devices, and features integrated overcharge and over discharge protection circuitry which reduces the risk of damage to the battery.. Even with the built in protection, proper care will need to be observed. As with all lithium batteries, do not overheat, incinerate, reverse polarity, mix voltages, or do any other potentially dangerous activity.
