I'm going on a 2mo deployment. thoughts on my batt in my ram

I would use a battery maintainer , like a trickle charger but automatic. They are only about $30.

A battery tender is the same thing. I use them all winter to maintain my RV battery. The other option is just disconnect the batteries.

Roy B is correct if you disconnect the battery your computer will have to relearn your driving habits.

I park mine for 6 mos/year. I hook it to a battery tender for a few days...then disconnect both batts completely. I like to put the tender back on it every 2-3 month's after that for a day. Always fires right up in the spring.

Use the trickle charger or disconnect the battery cables. If the batter is decent shape, the weather is warm and it will be fine.
