Title: O'reilly AGM8D battery info needed
Post by: Travelin' Man (RIP) on February 29, 2016, 05:03:01 pm
I need to know the total amp hours for one of O'reilly's AGM8D batteries. I have them installed here in Texas and need to set the dip switches so they won't over charge.

Thanks

Typically 8D AGMs are 220ah. If no one comes up with an exact figure that should be close.

I'll add my voice to the choir. Mine say 245AH @ 20 Hrs. as well.

The battery literature lists 1, 3, 5, 6, 8, 10, 20 and 100 amp hour rates.  I just didn't know which one to choose.

I believe you but I'm curious as to why the 20 amp hour rate is the one that determines total amp hours?  I should set the dip switches at 700 total for 3 batteries?

I think historically the 20-hour rate has been considered to be representative of the typical rate at which power is used from an automotive battery under normal conditions. For whatever reason, it does seem to be the "standard" when considering the energy available in the battery.

Thanks for the explanation David.
