I have some Hawker 39AH AGM batteries that I use mostly to power an inverter when I'm camping. I was reading the charging information on Hawker's web page about these batteries, and it says in bold "For repeated deep discharges the minimum inrush current should not be less than the rated capacity of the batteries".
Since I have a 39ah battery, that leads me to think the minimum current should be 39 amps. What?! I'm not doing any damage to the battery by charging it at 2-6 amps am I? I was under the impression that a slow charge is ALWAYS best...
