Blackcell IMR18650 Battery 3100mAh 40A Max

Great product and fast delivery

After trying 2 different blackcell batteries I have found that they do not last as long as a standard 26 2600mah Panasonic. After some research I have discovered that these are rewrapped batteries which could be a very quality that's why I believe sticking with a major brand is the best option.

I order 2 sets about 2 months ago. The charger said good. The 2 sets I got this week show bad on 3 batteries. Went to Central Vape today and got other batteries. Trash blackcell as I can’t trust them.

I bought these because that putz, Vapor Joe, recommended them. Freshly charged my mod says "low battery" when I try to vape at 40 Watts. Thanks Joe

I had high hopes for these batteries. They came in and they are beautiful. I ordered six just to replace my stock and not have to worry. Boy was i wrong. Batteries not keeping constant charge between married sets. One of them is slightly larger than the rest so its hard to put into my device. Just overall... terrible purchase.

The headline pretty much says it all --- I would never buy these again.

hit hard. don't last long. definitely not 3100 mah.

I just got two sets of these. Let them fully charge before using in a Nitecore I4 charger. The batteries are rated at 3100 mAh, but they last about 8 hours during use. My much older efest 2600mAh rated and Sony 3000mAh batteries still last longer than these brand new ones. Although, they are in much better condition than my old batteries and still have all of their protective covering on them. Just disappointed about the capacity. The pros about this battery are the price, the cons are pretty much everything else.

They work, but have a shorter life than some of my year old batteries with a lower mah rating????? At the price level it's fair but wouldn't get again.

works very well just wish they lasted longer than a couple of hours
