Charged these batteries for 8 hours. The lights only worked for 2 hours. Charged them again the next day and got the same result. Junk.

    • the description about that nub not being there and make sure you are buying the correct battery
I screwed up and ordered these and they don' t have the nub on the positive side. wouldn't work on with my solar lights, so I repurposed them for a flashlight. They even say in the description about that nub not being there and make sure you are buying the correct battery for your use.

    • They work
Having never needed 18650 batteries for anything before, I can't compare how these are compared to others. But they arrived charged, and ran a very bright light for about an hour, and took about the same amount of time to recharge. It should be noted that these are flat top batteries: if your device needs a raised button, you may want to look for different ones. I messed up, but was able to adjust these by adding a bump of solder. But if you can, it's best to start with what you actually need. ... show more

    • Compatible with my old flashlights and brings them back to like new again
I ordered this to bring back to life some old flashlights whose batteries will not hold a charge anymore. These batteries fit perfectly and charges properly in my charger for 18650 lithium ion batteries. The batteries also fit perfectly in my flashlights which used the identical style of 18650 batteries. The lights are now back to original brightness and once again lasts a long time. ... show more
