Next time I'm buying I plan to try and find some reputable companies for alternative batteries
Bingo. That's the sort of thing I'm talking about. Although I'd do a search first, I'd trust batteries from them for my expensive gear.I've always used 7dayshop's own brand camera batteries
How many spare batteries can you need?
I get about 700 shots plus with one so surely a good charged spare should be enough in which case buy the real deal or good branded make such as energizer and save all the angst
