I've had my SD MK II about a month now. When I first got it, I'd get approx. 20 hours constant use out of it. Slightly less than my MegaT battery, but stacks up in terms of mah.
However, I had months with mega T batteris with only slight degradation. After only a month, both my SD batteries are lucky to last 4 hours. I tend to drain them completely then charge again. I charge over night, under the assumption that when the charger turns green it stops charging. Am I right in this assumption?
I thought that the SD may be more economical after shorting a couple of 'nados with smokeymisers. If battery degradation is as high as I'm currently experiencing then this may be a false economy.
All advice greatly appreciated
