Description

Next-Generation 5500mAh Battery

From Nitecore's latest battery generation, the NL2155HPi stands out with an impressive 5500mAh capacity, making it an excellent choice for high-drain devices thanks to its continuous 20A discharge current. Compared to its predecessor, the NL2150HPi, the NL2155HPi features a bigger capacity and a bigger discharge current.

Featuring Nitecore's hallmark safety standards and precision engineering, the NL2155HPi reinforces the brand's reputation as a reliable source of rechargeable Li-ion batteries.

Premium Build with Safety Features

The NL2155HPi incorporates a built-in intelligent protective circuit and a pressure relief valve, safeguarding it against overcharging, over-discharging, and short circuits. Crafted with top-tier materials, such as nickel-plated stainless steel protectors that fortify it against impacts, ensure efficient conductivity, and fend off oxidation, the battery is further coated with a durable metallic film, bolstering its resilience against abrasion. Designed for longevity, it can withstand over 500 full recharge cycles, making it both cost-effective and environmentally friendly.

Solved all of my strobe problems!

I was having problems with my original battery that came with my P23i flashlight. When I would press the mode button to cycle through the lower power modes, my flashlight would be stuck on strobe. I lost my ability to cycle through the modes. I replaced my tail cap, and thought it could have been the battery. I bought this upgraded model battery hoping it would fix the issue, and it did!

Great purchase, working great so far. I am using it with the P23i Flashlight.

So far, outstanding!

So far they have been outstanding. The battery that came with the lightwas 90% charged out of the box the one was about 60% charged out of the box. Both charged very quickly and I have not had to change the battery yet.

The Nitecore NL2155HPI 5500MAH 21700 Battery works great.

I ordered this battery NL2155HPI as a spare for when I go walking in the woods. I switched the battery to give it a try and it worked great. it definitely lasted longer than the standard battery. I have used it on a couple of walks, and I still haven't needed to charge it. I use the P30i on mode 3 and the battery it last a long time.

I had to buy two batteries

I had to buy two batteries. The original battery didn’t work. I paid over $90 dollars for the light. And $60 dollars for two batteries. Hardly worth it the light doesn’t stay on very long. And there is a delay in the light. I would not recommend this light to anyone.
