Well I haven't used my LF gear in well over a year, so yesterday I pulled out the 8x10, set everything up, then pulled out my Minolta F spotmeter, and to my horror the whole spotmeter (even the outside casing of it ) had white crystals all over it.I opened it up and viola! battery acid big time!I spent the next two hours disassembling the thing and carefully managed to get all the acid flakes out and got it all cleaned up.Put a new copper top in it, and to my relief it still works.How on earth did that happen?The AA battery that was in it was a duracell and it could not have been in the meter for more than 2 years.I have flashlights that have had duracells in em almost 6 years and no acid so im a litte perplexed as why this happened, and want to make sure it never happens again.I'm not sure if I had left the meter turned on when I put it away.Could that be the reason?
