I tried to use it for my mosquito bat, it stopped working after 3 days
Specification of this battery matched that of lead acid battery that was in my mosquito bat Thinking this is a high quality replacement for that, I purchased and fitted to my bat It worked like a charm for two days. It is dead on 3rd day
