Authentic 25RS, 3.7V Flat Top Real 2500mAh, 3.7V 18650 Rechargeable Battery(2 Pack)

I did some searching for a better battery than previous ones I bought that have a short life. I read some reviews and found these to be the best choice. They were right. These work great! They last way longer than any others I have. Great purchase for my needs! Worth the price. Charge just fine. Thanks!

I have had zero issues with these batteries so far.They seem to hold charge for quite some time.However, I do mainly only use them for my military grade flashlight.I will also say this- now that I no longer use Double-A batteries, my flashlight definitely seems a lot brighter.So if your flashlight uses double-A or even triple-A; you will indeed notice a brightness difference.I bought one set of these, and a set of green ones (I believe by Samsung) and they all seem to work great.I do suggest buying a battery charger.

These batteries have been great for my mod so far. I haven't done any scientific testing on these, but I'll leave that up to the scientists. They charge easily and fit in my device. Cannot argue with that

I thought I was ordering the samsung 25r's. A little tricky on the word play, printing and color scheme as the samsung ones look identical. These are ok though for the money i guess. They drain quicker than the Samsung brand and probably wont last as long.

Had a tactical light need one of these. Perfect replacement and no issues in the 3 months I've used them

Worked like a charm.

After one week one batteries was dead and not charging properly.

The power lasts, even after many charges.
