first thing we should do with the battery is

check the water level before charging

distilled water only

Just remember that there are a LOT more electrons to stuff back into that battery than a car battery. Leave it on the charger for 3 days and check the water level every day.

Partially recharging it (24 hours from dead) will shorten the life of the battery as it still "counts" as a cycle, but it will die sooner. Batteries should always be completely recharged when the capacity drops to 50% (12 volts when rested for 12 hours) to avoid permanent capacity reduction.

Look at the graph to see how a "quick charge" makes it LOOK like the battery is full; but there is not enough deep seated electrons to give you the rated capacity (life).

If you don't want to install a battery disconnect switch all you really need to do is disconnect the negative cable while the camper is not in use.

Steve:

Thank you very much for the invitation. If I'm in town, I might take you up on your offer. I'm trying to plan a camping trip of my own around some doctors appointments and a couple of other commitments, but I really do appreciate your offer. I have a brand new camper I bought in Dec. and haven't tried it out yet, but I chomping at the bit to do so.

Once again, thank you for your kind offer.

Jim

Herk:
I followed your instructions and yesterday, when we took the trickle charger off, the battery read 12.83 on my friends meter. We took 3 measurements and they all read the same. (He said he always charges his motorcycle and lawn mower this way. He said to never use a quick charge as it heats the battery up too much. Trickle chargers are the best way to charge it up providing the water level is where it's supposed to be.)

I can't thank you enough for your help and good advice on this issue. I sincerely appreciate it. That chart was a big help. Hopefully, I'm all set.

Thanks again,
Jim
