Using a battery maintainer
I'm going to store my Ram diesel truck for about 5 months and want to keep the batteries charged with a battery maintainer. Will I need to disconnect the batteries to do this? ryoung

Do not use a GFI outlet. I did this on a car for 6 months and some time during the 5 months the GFI tripped possibly due to a power surg.
The maintainer dropped the battery voltage to about 3 volts which destroyed the battery..
I don't think the maintainer drained the battery. More likely, it was the onboard loads in the truck (radio memory, etc.) that drained it. Chargers have blocking diodes that prevent reverse current flow.
