Hey guys i am new to this forum, i have a question and would like some help. I have 2 sealed lead acid batteries each are 6V and 7.0amp hour. This weekend i bought a 12V 1.0amp trickle charger from Canadian tire. Ive got both the batteries hooked up in series so they are 12V at 7.0amp h, my question is how long will they take to charge and is it safe to be charging 2 6v batteries in series? Thanks guys
