awesome battery if it fits
March 15, 2023
I got 3 of these to get a better battery for my klarus xt21x the flashlight is awesome and even better with the nitecore 21700 battery problem I ran into is one of the batteries was to fat and got stuck in the flashlight got it out have no problem with the other two batteries I order another hope it fits . not going to try and return the one that the dia is to big because it got a little chewed up getting it out. because of the oversized dia I'm giving this battery 4 stars if I would have had this problem it would have been 5 stars

Good product and service

I made a mistake by taking 21700 model dimensions literally, as 21mm X 70mm, not knowing that the USB port adds a little length, so it would not fit in my device. The service was great though, and we quickly arranged a return/swap for something that will work. Some other companies won't do that.

No warnings about the length!

Bought these, ripped 'em open, charged them and when I tried to put into my device I discovered they were too long. THERE SHOULD BE CLEAR WARNINGS IN LISTING THAT THESE ARE NOT STANDARD LENGTH!

Great Battery
July 21, 2021
I really like batteries that have a micro USB port for charging and these have it. I can even charge them in our Jeep Wrangler with multiple standard USB ports all over the vehicle.
They charged easily, of course. But last longer at high drain, then I expected. Just an easy battery to work with , just as easy as working with Battery Junction. I use Battery Junction for all our battery and flashlight needs. They carry the brands I like and need. I've been a prepper for many years. Not crazy but enough that I feel that I could take care of my family in almost any event. We off road a lot ( not recently during the COVID-19 pandemic though) and need lights if we get stuck off-road at night or in dark places. We usually don't go alone but rather with a Jeep Club so others may even need a light and we have them, all supplied by Battery Junction.

Really great battery!

I bought this to use with a Fenix flashlight. The built-in USB C charge port is super handy. The storage capacity of this battery has carried me through two Storm-related power outages with no loss of performance. Best of all, it is super easy to recharge!

This battery supports up to 15A of draw so, I get full output on my flashlight until it heats up and throttles itself. This battery is really strong holding a lot of charge and will deliver the Amps needed for high draw flashlights.

Highly recommended!
