Keeping battery charged in TV

A little OT as the car in question isn't really a tow vehicle but same idea...my aunt has a car she doesn't drive but wants to keep running. It is a Chrysler Pacifica and the battery drains quickly when it isn't used. What could she use to keep it charged? It is outside so some kind of solar charger might work.

Try a Battery Minder or Battery Keeper, there's a couple other 1.5 amp desulfating battery maintainers. I use one on my trailer battery when it's snug under it's carport. I also used it last winter when I was traveling for 3 months+. They work great.

I have a 1.5 watt solar panel that is designed to keep batteries charged on an automatic electric gate, I use it just to keep the battery topped off while my egg just sits around in the yard.

I use a battery tender on my classic car when it's stored.

Solar Battery Charger...... Just put it in the window facing the sun and forget about it.

The battery minders work, yes. But what does "battery drains quickly" mean in days/months? I think a good battery should hold enough charge to start a vehicle for 3 months. And starting at this frequency is a good idea if a vehicle is not in use.

There are Phantom energy draws in cars nowadays the memory and clock in the radio, probably some memory in the onboard computers, the easiest thing to do is just disconnect the battery.

I also disconnect the battery in my Cadillac Alante that I usually only drive in the summer. The only problem is that it takes awhile for the computer to re-program itself. During that time the fuel economy is horrible and the car doesn't perform well.

I don't know exactly how long this takes, but I would say a couple of days and around 100 miles.

I've decided to go the 'battery tender' route. Last winter I used the car a couple of times and forgot to disconnect the battery after the last use. It sat for a couple of months in that state and drained the battery so completely that it wouldn't re-charge.

Don't ask what I paid for a new battery. I'll just say that using a battery tender might not make me a rich man one day, but it will most certainly help keep me out of the poor house!

The tails of woe I've heard about computer resets in automobiles. Now when you disconnect the battery for any length of time the computer will reset. Sometimes you have to drive several miles to get things straightened out. You may even have to drive around in circles to reset the compass if you vehicle is equipped with one.
It's much better to use one of battery maintainers and keep all the computers and etc. working.
