Charge rate up to 40%

[joewalton2003]

It is my understanding that the batteries will dictate how much
amperage they draw. In other words, if your batteries are down and
they attempt to pull 150 amps from a 100 amp charger, two things will
happen. First, you will overload your charging system. Second, you
will shorten your battery life by allowing your batteries to accept a
surface charge. Deep Cycle batteries need a deep charge to retain
their capacity. There is excellent information on this subject at
David Smead's website, - amplepower.com.

into the batteries in about 1/2 hour, and then the rate would start
dropping, but it would still be putting it in way faster than a 75 or
100-amp charger for quite awhile. In the comparisons we were doing,
75 to 100 is not a huge increase. 100 to 200 is huge.
