2500Mah Imr 18650 Battery Rechargeable

I have multiples (5) of these which I have purchased over the past 4 or so years. They charge 123/16340 and 18650 Li (I have not used them for LiFePo cells such as the SureFire 123 batteries however) and IMR 123 batteries nicely. I have used these chargers with Fenix (16340), Olight (IMR 16340) and Surfire (18650) batteries and they have worked well. The display is very helpful for getting a sense of where the batteries are in the charging cycle. This charger does not, to my knowledge recondition batteries. Also, there may be calibration differences among charger or even in one charger itself -- individual charger may read cells' voltages differently including reading them differently in the charger's own left and right channels. This has not been any sort of a problem, as far as I can tell, with the cells I have been charging. Another small niggle is that the input cable fits a bit loosely into the charger.

Nitecore 18650 Li-Ion Rechargeable Battery is a great source of stored energy. Being rechargeable makes this battery cost effective. This Nitecore Li-Ion battery has demonstrated its dependability in a flashlight over a period of seven hours of intermittent use. Great product!

If you need 2500mah batteries, these are great and the charger works great.

I'm very happy with these 18650 batteries.

Great light but getting the rechargeable battery will make you use it so much more often.

This battery is everything I would expect out of a quality rechargeable battery.

Quality, well made and designed rechargeable battery.

I love the fact that the battery is rechargeable!

One of the best flashlights I've ever owned. Be sure to use with a high-capacity 18650 (3600?) NItecore battery.

Package arrived quickly, came with everything needed to get started 18650 battery, 2 bay charger, video cord and all. A little slow on start up, and wish it had auto focus. Other than that, this thing is great. Easy to sight in and operate. multple color pallettes.
