Hooked up my two 12 volt batteries in parallel over the weekend. Everything looks good. Holding a charge at 12.6 volts. Here is something I don't understand. When the camper is plugged in I read 13.4 volts on the cable coming from the charger. When I plug everything up it only reads the 12.6? Is that right? I understand the charger on the camper is not going to be great is that all the higher it should go? Half of me understands that once the battery is 100% charged it can't go higher but the other half thinks it should read higher when it is charging.
The other question in charging on a separate charger/conditioner. I have two situations. 1) I have a small solar charger that I will use to maintain the battery in storage. 2)I have a conditioner that I want to use a couple of times a year. Can I / Should I hook the positive to positive and the negative to the camper (for ground) or directly to the negative?
Thanks in advance.
