بطارية XTAR 4000 mAh 18650 ليثيوم أيون لأضواء Sea Dragon Mini

I've been using this battery in my dive light for about two weeks now. It holds a charge noticeably longer than my older 3500 mAh cells. The slight extra capacity makes a real difference on longer dives.

It's nice to see a 4000 mAh 18650 that actually fits snugly in the battery compartment of my mini light, no rattling at all. Lasts a good two dives on a single charge, which beats my older batteries.

Swapped these into my dive light before a night shore dive and got a solid two hours of run time on high. They fit the battery compartment snugly with no rattle, which my old cells always had. Charging back up to full was quick too.
