RV Battery Charging

I have removed the battery from my 5th wheel camping trailer. The battery is currently stored in my basement garage. I want to connect a "maintenance" charger to the battery to maintain the charge during the winter months.

Would it be safe to connect the charger and leave the battery and charger in the basement garage?

Is this location considered a "well ventilated area" as per the charger instructions?

I do not have a secure location outside to do this.

i think it should be safe.
use the minimum charging rate.
maybe plug the charger in to a small timer(2 hrs a day)
did you wash the top off berore bringing it in?
(needs to be clean & dry)

Ken, I tandem my motorcycle battery maintenance charger (probably 1 amp) off the receptacle that is timer controlled for my diesel heater. Only comes on from 2am to about 7am. Just long enough to heat the engine up for a good start, and long enough to top off the battery. Constant charging may not be a good option.

Thanks, Larry.
I bought a charger which is supposed to have a maintenance or top-off setting. I am green as a gourd on this. After reading the instructions, I became concerned about the hydrogen gas generated during charging. I think I will look for an outdoor location, dry, of course. What do you think?

If you are only maintaining an already fully charged battery you will have no problems with an off-gassing hazard.
You do need to use some common sense but the risk is when the battery is fully discharged and the cells are bubbling vigorously.

Just keep it in a relatively open area and if in a plastic battery box remove the top cover.

I have a floating charger on my motorcycle battery, it turns it self on and off as needed. I keep the bike in my garage and havent had any worries about gas buildup. Like Greg said the biggest danger is when the battery is completly discharged, or if you over charge the battery.
