3.6V | 4000mAh | Protected Button Top

The Nitecore NL2140 is a 21700 battery capable of powering all of your brand new flashlights at peak performance. With a protected button top and 4000mAh capacity, this battery is designed for incredibly long runtimes. Not to mention that its higher voltage will easily generate higher output modes in flashlights. The NL2140 is equipped with multiple external safety features from nickel-plated stainless steel protectors to encourage good electrical conductivity and oxidation resistance and coated with a durable metallic film to guard against abrasions, this battery will last a long time in your flashlight of choice. Those external safety measures are matched by the internal safety measures within the NL2140 like high-temperature resistance, pressure relief valves, built-in PTC to inhibit high current surges and a microporous barrier that protects delicate internal components. This battery is perfectly suited for the New P12.
