Hello all,
I am needing advice on what battery I should choose. My system in question has a 35A load at 12V. I need a battery that can supply this. The battery can be fed continuously during load by a power source of 14V, 60A or 70A via alternator.
I would like to stay as small and as light of a 12V battery as possible. I have looked at lawn-mower batteries and motorcycle batteries in wet and dry cell.
The problem is, most of them do not list Amp Hours, but only Cold cranking amps. My question is, how do I size a battery to be put under a 40A max load without picking the wrong one and destroying it? This will be a constant continuous load at times.
If these are listed by Cold cranking amps, how high is high enough to be safe for a 40A load? I will be feeding this battery with an alternator @14V much like a car, so it wont be discharging super quick. Any advice greatly appreciated.
