Just wondering...
If I am not going to be using a battery (BP-511) for a while is it best to store it fully charged or fully discharged or does it make no difference whatsoever?
Only reason I ask is I have several spare batteries and I used one today which I hadn't used in a while and I think I put it away fully discharged but I gave it a charge before using it and it died very quickly. Maybe it's just old. I thought I'd ask though so I can store my other batteries in the best conditions.
Cheers,
Nick
