I don't use NiMH, just storing a mate's gear who just got into airsoft. He used the battery today and I want to know the best way to store the battery?
They're not volatile batteries so anything method of storage will do tbh, as long as it's not hot - some people even store them in freezers.
As duck said, they die pretty fast overnight so it's pointless chargin them fully and leaving them expecting to have enough juice for a morning session.
