I bought a brand-new 12-volt battery
I also bought a trickle charger. I keep the battery
in the garage all the time except when I'm camping, connected to the charger.
When I made an overnight trip in June, the battery
took a day or so to charge. I had a hookup, and the battery charged while I was driving, I assume.
I took a 3 night trip over the long weekend. I had a hookup this trip also.
I've had the charger on the battery for 24 hours, and it's still charging. But I had a hookup all weekend, so it should have been constantly charging. And when I drove, it should have charged. In theory, the battery shouldn't have been discharged very much.
I don't need the battery now. My next trip won't be for a month or so. I'm just making sure this is normal.
