I'd like to know more about getting a solar panel setup for charging the battery. Any good info on that?

Thanks

There is no 'hibernation mode' for lead acid batteries.  Once they are filled with acid by the manufacturer, the clock on their lifespan starts ticking.  Every day that a battery is not kept 100% charged results in some amount of irreversible damage that is done to it.

For very down-to-earth information on lead acid batteries, I would strongly recommend that you listen to at least the first podcast shown at www.battery1234.com.  It will save you money and troubles.

It is not good to leave a battery in a partially discharged condition.  Plugging in is the best way to charge the battery.  Solar is good, too but not always the best.  There is a wealth of solar info on this facebook group's page.  We have solar and love it.

Only thing I would recommend differently is to charge every 30 days.  With a self-discharge rate of 1-3% per day when it is warm out, 30 days is the max.  You can get away with 60 days during the winter since the self-discharge rate drops when it is cold.

Purchased our 2 12V batteries in March and June of 2011.  Both are still holding up real well and are NOT maintenance free.  As furpod stated, and we follow that protocol, check the water level a couple times per year.  I purchased a Sears battery charger at a yard sale about 10 years ago for 15 bucks.  It has all sorts of bells and whistles and charges both 6V and 12 V but I have mainly used the 2amp trickle charger option for my batteries.  Takes about 2 days(per battery) to bring them up to charge after sitting in the garage from October thru most of April.  In the fall before putting them in hibernation mode, it takes about 8 to 10 hours in the 2 amp trickle mode.

Thanks.  When I bought the trailer, because I do a lot of dry camping, the dealer said that two 6V were the best for my needs, the only thing they didn't say was that the batteries were not maintenance free.   Almost considering to go back, and tell them to install dual 12V maintenance free batteries.


For dry camping a pair of readily available 12V batteries would be a big step DOWN from the two GC2s. The only known true deep cycle 12V batteries are the GC12s from Batteries and Bulbs and several from Trojan, particularly the the T-1275. Both are intended for the golf cart market so they're more readily available, but not at Wally World or auto shops.

Buy a jug of distilled water and a 50cc syringe.  topping off batteries is way better than maintenance free

I guess charging in a garage is a little more "ventilated" then if I charged them in the enclosed batter box they sit in, on the trailer. lol

Even 12v batteries need maintenance. Especially when used the way boondockers use them. The only maint. you will need to do is check the water once in a while. I do it about twice a year.
