I think there would be no problem if you use it for your test. If one of them would deplete faster than the others --which would happen after a while-- then there would be a problem because a battery in parallel which is not the same voltage as the others becomes a LOAD to the entire circuit drawing huge amounts of current. But this would happen after a while, I don't think you would have trouble if you use it for your test.Hello,
I have 2 batteries and each one rates 12vdc, 86Ah, and have another 2 batteries each one rate 12vdc, 108Ah. Is there any major issue if i connect them in parallel to test an Inverter Power Supply?
Please help.
Thanks

If two batteries with different terminal voltages are connected in parallel, you can get into trouble straight away.I think there would be no problem if you use it for your test.
