"Long lasting battery, quick charging Li-Iom platform. Only type I carry in my equipment!!!"
"Bought some of these batteries to use in high drain lights. Still reviewing conducting tests on them. What I have found out so far. . . On standard lights they do last longer, on high drain lights they do last slightly longer, but take longer to recharge. The cost factor, I can buy 3500 to 3600mAh batteries, cheaper, recharge them quicker than this battery. I guess it boils down long term charge/recharge cost factor. Darn good battery, just wish it would last a little longer in high drain lights. . . . Thanks, Charlie"
"Finally an 18650 battery that has true 4 mah capacity and a 16340 battery with 950 mah capacity. . . my experience with Nitecore batteries has been nothing short of awesome"
