solar powered battery maintainer.

I have been driving my truck less and less. I have a work vehicle and have really started using the wife's car for the running around stuff. Plus I have almost 13k on a truck that I don't drive everyday in less then a year.

I did not drive the truck for two weeks, went to start the truck remotely (another issue I'm having) and it did not start. I went out to the truck to try the ignition and the truck barely started. Just a extremely low battery. Plus its been cold. I do have a flash light (streamlight) plug in to the 12v source in the center console.

I was thinking of getting a solar powered battery maintainer. But all the ones I see seems like there is no switch and no real permit mounting and everything it will need to be disconnected when you start the truck. I would not mind a switch but I don't want to have to unplug and plug in ever time.

any suggestions.

P.S. I don't park in a garage because my garage is not big enough. and I don't have any out door power ports on the house. But I am thinking of running power out to my driveway on a post. but that's a little bit of an involved project.

This is the only one I found with a controller that senses charge and shuts off. I use these guys plug-in tenders for my boat and other batteries that sit around and haven't tried a solar unit, but if this actually works, it would PERFECT for my boat and possibly your application. I swear by these dam things and always plug em in to my cars if I'm going out of town, or not going to drive the vehicle for even a weekend (especially if the temp is below 35 degrees). I mount them under the hood and wire em into the battery and hide the plug. Never had a problem starting or running the vehicles with them wired in, with the battery or the units. I am convinced that liberal use of these will improve battery life dramatically as car batteries love to stay at a full charge. The solar type appear pretty pricy and you can buy 3 of the plug in types for what this costs, but if it works without electricity input, that would be uber-sweet and pay for themselves in electricity and battery life.

I did notice this other piece for use with another solar panel...

So what non solar power one do you use? I'm looking for one for my pop-up camper.

I've got a Goal Zero Guardian hooked up to 2 15W panels. Works well so far but the Guardian has been discontinued, though I have heard they are releasing a new product in June.


They also have the Maintainer 10 Trickle Charger that would likely do the trick for you:
