Hate to be a nay sayer but, thing about quid shop packs of batteries, have you used the AA and AAA batteries from a quid shop? they are complete and utter **** hold about the same amount of charge as a squeeze of lemon (that's when they don't melt and destroy whatever you had them in), the watch style batteries are no better, I had a propa pair of batteries in a tip light for months when they got a bit weak I replace with some quid shop batteries which at best lasted 2 or 3 short sessions per pair.
It's a false economy.
