Charging AGM Batteries

Pooh Bear
15 years ago

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.

Thanks.
