Battery on Rpod dead

I've had a great summer getting much use out of my Rpod.  The Rpod has sat for the last 3 weeks.  I'm taking it out Labor Day weekend.  Today I went to the covered storage where I rent a space to store the rood.  I found the lights wouldn't come on inside the Rpod.  Nothing would operate (slide out) suggesting the battery is dead.  I am planning a trip this weekend (with full hookups), will everything else remain uneffected in the Rpod even if the battery won't recharge?  I really don't have time to get a new battery.  I'm going to bring the Rpod home tomorrow and plug it in.  Hopefully the battery will revitalize. I only now learned you should disconnect the battery when the Rpod sits.  I didn't the battery would go that quick.  With that said, I left a plug in air freshener in the kitchen outlet.  Could that have discharged the battery?

The RPOD and most other modern campers have a propane detector that draws current from the battery continuously. The RPOD has a small additional load from the thermostat. These loads will deplete a battery in a few weeks. That's why you should disconnect the battery or keep a trickle charger on it when you store the Pod. Having discharged the battery once it will have a shorter life, but should recharge when you plug it in at home. Charge it over night to make sure. Depending on how you use it you may never notice the degradation. Most experts recommend not discharging  a battery more than 50% and to never leave it totally discharged for any length of time. The plugin deodorizer will have no effect because it runs on 120V, not 12V. 

A battery cut-off switch will simplify things for you. Otherwise, you should disconnect the NEGATIVE (-) lead from the battery. Disconnecting the POSITIVE (+) cable can cause some unexpected fireworks if it should contact metal A cut-off switch will keep you from having to mess with the battery terminals. It is not too hard to install. There are several pictures of different ones in the forum including the one shown in my mods. It has come in handy when I was doing some work where I wanted the power cut off. It has also been handy for when I had to take my R-Pod to the dealer for some warranty work.

+1. If the switch is on, it charges.
