3.7V 2 Packs Button top 18650 Rechargeable Batteries for Headlamp, LED Flashlight, Electronic Devices etc

Fit and works perfectly in my Redline flashlight and charged up quickly

Direct replacement for my laser

I needed the batteries for my ring doorbell

I have a few of the Kami (also sold on Amazon) wireless security cameras outside that take these type of rechargeable batteries. The cameras come with the batteries and a charger, but when its time to recharge them, I decided to buy another set of them so that I could just go up the ladder once to swap the batteries. A full charge takes about 4 hours. Having the extra set already charged up saves me time! It turns out that these batteries also work in a portable fan that I have. Tip: be certain that all the numbers are the same as the batteries your original device requires. There are some numbers that do not matter, but the Volts and mAh need to match. Also, when you get them, take a permanent marker and draw a + and - really big on the correct ends so that you don't mistake one side for the other and damage your device. The ends look so similar and the + and - markings are very tiny.

Was looking for some replacement rechargeable batteries that will go with my solar lights. These batteries are the correct power that came with the string of lights. They don't hold a charge very long so it was a waste of money for me. Bought them in August they're outdoor lights so they're not turned on a whole lot, they do not hold up at all. My mistake. I should have checked them more often. I wouldn't buy these again and I can't recommend them to anybody unless you use them more often and if they do fail you can get it replaced or sent back under the 30-day time limit.

Muy buenas esa yo lo que ordené
