This is totally normal if you store your camper for a time. The info presented above is correct.

There is a draw in the battery even when not camping. For this reason, lots of folks use / install a battery disconnect to remove the 'parasitic draw' factor.

Just a thought - consider adding a battery disconnect and shut down the power to the coach when she's not in use and you should have some power when you hook up again.

Solar is another option (but out of my league for $$$ and mechanical abilities). This would keep your batteries charged when the RV is not in use.

the time my camper has been stored is just a bit more than 2 weeks. took battery to o'rielly's to have it checked, they put it on their little charger/tester and 30 minutes later it said i had a full charge. we shall see in the morning

i bought 2 wing nuts to make battery disconnect just a bit easier, so total cost this eve so far has been a whopping $2.60 including 30 minute recharge. will see in the morning if the 30 minutes was worth it, or if i just spent 1/2 hour jabbering with the parts guy. i really do appreciate his effort tho.

Are you not able to plug your camper in while at home?

no, i have to put it in storage. not because of crabby neighbors like my neighbors down the street have, but because i live on a cul de sac, have 5 vehicles (wifes car, my truck, the old car in the garage and the kids 2 cars) and parking is at a premium. i only bring it home a day or 2 before we are due to head out.

maybe after 1 of the kids leave, it will come home permanently to roost.

That 30 min charge was only a surface charge. I suggest that you try to fully charge it tomorrow.

Yes, the tech was car guy. Starting batteries have very thin plates and can take a "quick charge" and be "good to go." House batteries have very thick plates and take a LONG time to charge.

30 minutes is NO WAY long enough to charge a deep cycle.
24 hours on a dedicated charger minimum from dead.

You have to replace 75 amp hours of charge. At 20 amps steady it will take 3.75 HOURS of charge. This is not possible because 20 amps constant will BOIL your battery dry. The multi stage charger will detect the increase in voltage and step the charging current DOWN. Each step drops the current down to less than an amp for the last 20% of capacity.

there should be enough in it now to raise/lower landing gear even tho im not opposed to hand cranking. maybe some time on the house current before we go, and then again at the cg will do something for it til we return sun eve.

i need to invest in a multi stage charger for all my batteries. rv and old car both.

My money is on "you will be cranking" so find out where the crank is and where it goes. A good 4 stage charger (with a desuplphation phase) is a tool that should be in everyone's tool chest.

Is on my "To Buy" List to replace my Ship and Shore 3 stage unit.
