Blackcell IMR18650 Battery 3100mAh 40A Max

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

Suppose it’s my fault but I went with these due to the higher mAH but they don’t last as long in my Snowwolf as the lower mAH ones. Not Central Vapors fault because I should have called and asked their advice first but hey, these batteries work

These batteries last about a tank and a half of juice(5ml per tank) at 50watts. Price is good but you’re gonna need more than a couple.

These batteries last at least the whole day of vaping

Super cool looking design and the capacity seems good so far and they came with a free battery case when I bought a set of two batteries. The case is very durable, at least it seems to be so now. I already ordered a few more of the BlackCell 18650 batteries and leaving a set at home as a back up.
