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.

"Battery is what it is but you need a new charger to charge this battery. My charger for the old p12 will not work on the new battery. The 5000 that comes with the flash light has a charging port. I do not know why they recommend this battery. Should have been another 5000 not a 4000."
"First experience with this battery and as usual with Nitecore products it did not disappoint. Just purchased 2 more for my light."
"These batteries are supposed to be 21700. . . 21mm diameter x 70 length but they are longer (75mm) due to the protection circuit so not a true 21700. . . . and they do not fit in the Nitecore charger that says will accept 21700 battery. Battery may be decent quality bit the size does not match the name. . . . disappointing."
"Long lasting high quality battery with the recognized well crafted tradition from Nitecore . At excellent price and fast delivery from Battery junction. As always very satisfied with this buy. Highly recommended"
