Idle Jeep Wrangler while towing?

Morning everyone,

I have a question? Is it OK to let a Jeep Wrangler idle while hooked up to MH for towing?

The reason I asked is my battery was dead after towing for 2 days. Fuses checked out OK so not sure if issue was new install of Stay-in-Play brake system or if battery was just old (5 yrs old). I had to replace battery and I don’t want to buy another new battery when I drive back 2 days (if the problem is brake controller).

So i thought I’d see about idling while at rest stops on the way home as a precaution.

Thanks
Ezgoin

    Arizona? 5 year battery life is GREAT for Arizona. 120* heat KILLS batteries. Time for a trip to Costco or Sam's Club to buy a new battery.

    No need for all that excessive idle time. 5 years is max for a wet cell battery. As long as there is nothing on there should be no draw. You don’t leave the key on while towing do you? There is no column lock so leaving the key on isn’t necessary.
    You could always run a charge wire from the MH 7-way to the vehicle connector and then to the battery.
