- Proper charging is necessary.
- Do not allow to discharge more than 50%.
- Keeping your battery charged through the camper's converter is ok as long as it is a 3-stage converter, which most new campers have.
- Your trickle-charger should work fine as well.
- Batteries should be fully charged after use.
- If you plan to store the camper for more than a few days without charging, than disconnect the battery from the camper.
- Wear old clothes and goggles when working on your battery. Acid hurts.
- Keep an eye on the water levels. Flooded/wet batteries need to be watered periodically and the plates must not be exposed. Use distilled water and water only up to the marks.
Its a little more than you asked, but it will help you to keep your battery healthy.
To add to this advice, 50% of charge is not 6V,.. like many may think. Here is the scale of charge:
State of Charge / Specific Gravity / Voltage 12V
100% 1.265 12.7
75% 1.225 12.4
50% 1.190 12.2
25% 1.155 12.0
Discharged 1.120 11.9
I have a Battery Tender that I use on my Deep Cycle battery when taken off the camper for storage in the Winter. Once a month, connect it and leave it on for the full cycle of charge and float.
During camping season, if you are at a campground every 2-3 weeks, you may not have to disconnect the positive terminal. You may have a CO/LP detector as a slow draw, but you may be fine still. If going to be parking the camper for 3-4 weeks between trips and you cannot plug the camper in a few days before you go, then I would disconnect the positive terminal between these trips.
Your PUP likely has a converter for when you are plugged into the campsite shore power (30A or 15A) or at home to a 15A circuit. When plugged in, this converter will charge your battery and maintain it. See your owners manual for information.
Welcome! It is also helpful to post your camper info in your posts, or add it to your signature line so we know which model you may have.
