Charging AGM Batteries
I have a couple of big AGM batteries sitting here
next to my computer using them for backup power.
I have heard that AGM batteries have to be charged very
slowly. At a rate around one amp. I have heard that charging
them at a higher rate will kill them sooner. Is this true.
I bought a battery charger/maintainer to keep them charged.
I charge them seperately, never together.
My computer is on a UPS and when the power goes out I have
time to unplug the UPS and plug it into an inverter that
I have hooked up to one of the batteries.
Most of the time the batteries just site here un-used.
They were practically new when pulled from service.
The batteries came out of a power wheelchair.
And if I am reading the label correctly they are each 12V 73AH.
So, do they have to be charged slowly, and will the charger
I bought do the job or do I need something different.
