When auto-stop-start becomes more intermittent....

Make sure when charging - if charging the two together like in the system (in parallel) you charge through the IBS and not a blind charge. Make sure the negative charger lead is on top of the IBS.

The problem with charging both together, in parallel when they are both dead is that one will be full and the other not. It'll start, but it likely still detected a low state of charge or low voltage in one - probably the crank battery.

My aux battery on 2 amp charges in a couple o hours or so.
My crank battery on 10 amps takes several hours to complete all 3 phases.

Both batteries will charge at the same time with the difference being the battery charged through the longest cable will trail slightly due to the higher resistance of the longer cable.

I'm wishing mine would just stop working all together. I hate that thing

Turn it off

Turn it off

LOL - pushing a button is tooooo hard. It's just easier to complain about it and hate it and validate your hate for it by finding someone else who hates it - simply because they do.
