I bought a brand-new 12-volt battery in May.

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.

Any ideas?

Trickle Chargers are always charging. Here's a good read:

This is why they are called "Trickle Chargers".
They trickle a small charge and are designed to provide a very slow long term charge to help maintain a battery.

Faster charging is also known as "Bulk Charging" and is designed to provide a rapid charge and not just a trickle.

If you have the battery connected to the tow vehicle alternator while towing this gives something more than a trickle but less than a big bulk charge.
This will be more like Bulk than Trickle charging though which is why it is so useful.
On the other hand,only a charger gives a safe,monitored and controlled charge as the tow charge just keeps pumping it in whether it should stop or not.
