If you ask me this is the rechargeable battery design flashlights have been waiting for. With one in the PD40R and one fully charged I should be in good shape next time power goes out.
Corey L. (verified owner) –
Excellent batteries. Have purchased at least ten or more in the past few months. Will order more as needed! Thanks again.

These are great maximum amp batteries. I ordered two of them as spares for my Fenix lights.

These rechargeable batteries last hours upon hours. I have 2 for my flashlight and never can run either completely dead.

I own three of these batteries, and absolutely love them. This newer 21700 format allows for the perfect combination of size, output, and runtime. It actually turned out to be MUCH more convenient than I’d even planned to have the built-in USB-C charging capability! There are almost always USB-C charging cables available to me….multiple rooms in the house, in my car, at my office, and even at the homes of family members….all of which makes it very convenient to be able to charge these without trying to plan on when and where I’ll need to have my battery charger. These batteries charge quickly at 2-amps via their built-in USB-C, and have rock-solid consistency during use and seem like they just keep on running! These batteries make me want to keep buying more 21700 flashlights 😀

I carry this light/battery (PD36R) daily, and while it doesn’t get heavy use…it gets used every day. I’ve had it for about a month and have only had the charge the battery the first time out of the box. Excellent!

Kevin E. (verified owner) –
Tons of juice. Minus one solely due to the lack of onboard charge port combined with the inability to charge in my nightcore charger. I have been forced to charge it inside the PD-36, which is inconvenient when I’d rather swap it out and charge separately. This is a trivial issue though, when seeing the power and capability this battery provides.
Chris B. (verified owner) –
Good

I have been using this battery with the PD36R for a few weeks now. I use it nearly every evening when I take the dog for a walk as I live in the woods, probably for 15 to 20 minutes at a time at a lower setting. I fully charged the battery when it first arrived, and I haven’t needed to plug it in again since. By contrast, my old Mag light would go through D cells at the rate of 2 every couple weeks on the same walking path, and those were not rechargeable!
Alan Horne (verified owner) –
I am still (2 weeks) on the 1st battery!
