Our prado & subaru will be sitting in the carport unused for 10 weeks while we travel oseas.
Prado has dual battery setup - cranking battery & AGM auxiliary connected via Redarc DCDC unit.
Subaru has a single cranking battery.
I have a single 20A Projecta battery charger and a couple of sets of jumper leads.
Assuming all 3 batteries are in good health & fully charged to begin with can i maintain them as follows.
- connect battery charger to Prado cranking battery
- one set of jumper leads from Prado crank bat to Subaru
- disconnect aux AGM batt and connect to crank batt with 2nd set of jumper leads. Note that i asked Redarc tech support if the DCDC unit would keep aux charged in this situation and they advised against it. They gave reasons that i didn't understand.
I figure the subaru side will be fine but i recalling reading somewhere that charging different battery types hooked up in parallel is not a good idea. I don't want to wreck the AGM.
Would appeciate yr advice.
thnx. Frank
