Ok, I put the absorb charge time back to 3 hours in the Magnum charger settings. I changed the amp hr (P3) setting back to 870 ah in the Trimetric 2030. I think the P2 setting should be 1.12 instead of 2 so it doesn't show 100 % full until the amps are around 10? Is this correct?

Today, I discharged the batteries to -192 ah, and it showed to be 79% charged and 11.9 volts under load. I isolated the batteries and checked with volt meter and got a reading of 12.3 v after around 5 minutes. This makes me alot more comfortable now that I understand a little more about it and have more usable amp hours to work with.

Thanks for eveyone's help and input on this issue.

Voltage charts are at resting state and at the battery terminals.

Any load will reduce the voltage.. any connections that are less than perfect (Which means welded) will reduce the voltage

Any length of wire smaller n cross section than your leg will reduce the voltage Even a wire as big around as your waist will reduce voltage (only you won't be able to measure the reduction).

The Tri-Metric shunt will reduce voltage. (50mV at max current).

Does this help?

Home is where I park it!
