They say it wont work in real cold like a car battery- lead acid. Its
Alkaline, I did not know alkalines were rechargable, ive always read
to not recharge alkalines and that they cant get back to 100%. I
believe you cant get more that 60% back into it. 30v, might have a bad
effect on your electronics. I would not waste money on it.
