battery discharges when stored

Hey Folks: When my '12 Windjammer 2609W is parked; all systems off after a thorough in/out walk around check; CO monitor only device on; battery is dead after a few days.

What am I missing,....where is the current draw?

Hopefully your unit has a Battery Disconnect switch put there just to allow you to turn off the current drains like that detector. If not, you have to disconnect the negative battery terminal wire, or install that Disconnect switch yourself.

Thanks Barry: A disconnect switch is on next week's 'get list'. But I'd love to know what the current draw is.

Barry: I should have added,.......one wouldn't think that a CO monitor would draw enough 'juice' to flatten a fully charged battery in 3 days?

CO2 detector, Radio memory, lots of equipment has parasitic load that will kill a battery in short order.

CO, by the way; CO2 is carbon DI-oxide not MONoxide!

a 2 watt panel won't maintain a battery even with a disconnected battery . (2w/12v=.17amp and that's a best case installation)

You are correct that CO detector should not discharge a battery in 3 days. BUT, if your battery has been completely discharged it damages the plates in the battery and it takes less and less to completely discharge the battery. Also, each time you completely discharge a battery it cuts it potential life quite a bit.

Unfortunately, lead acid batteries do not take kindly to being discharged below 50%. I'm on my third on a 4 yr old trailer do to my ignorance on the first on and the dealer not paying attention on the second. I try to keep the present one from going below about 75% charge.

You may want to ensure that you don't already have a battery disconnect switch somewhere. If you go to the Forest River Windjammer site it says the switch is standard equipment for their new models. I have a friend who has a '12 Windjammer and it has the battery disconnect switch. It may be stuck away somewhere.
