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?

- I have a collection of Battery Tenders. The 3 amp units do a great job on my CTD and single battery cars. I don't disconnect anything on the vehicles because the 3 amp units provide way more than the parasitic loads. Craig

Not sure what you mean about tiny loads that should not be there. The maintainer that I had was the load that run the battery down.
Some maintainers put a small load on the battery even when they do not have a power input.- Peek A Boo spurious loads are about the only thing that can upset the apple cart. That, and as mentioned above -- extended power outages in conjunction with tiny loads that should not be there, anyway.
- 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 put mine on a timer for 8 to 10 hours a day.(coldest hours of the day) It doesn't need to be on 24/7. Done this for 13 years with my truck and no problems.
- Slap it on and plug it in.
- no this way the clock and the computer will be running which is not a bad thing
