At some point I will replace the 75 amp hour ones but right now don't have another use for them. They not even a year old yet so I hate to just get rid of them but I don't want to hurt my new batteries.
Is there some way of doing this that will make use of the old batteries, and the XM1800 watt inverter as well, I will be replacing it too with a Aims 4000 watt pure sine.
Any advice will be greatly appreciated.
Thanks
Don

As long as the chemistry of the batteries is the same (Lead-Acid in this case) I see no way the lower AH batteries can affect the charge ability of the higher AH batteries.
