I own a truck, but I don't drive it every day. The alarm keeps dying after four days of continuous use. That not only destroys a regular automobile battery, but it also makes starting the truck difficult. I chose this solar maintainer after doing some research because it's well-made and quite straightforward. Due to its extremely low power, automobile batteries don't need to be overcharged. The one drawback, or caution, is that if you leave it plugged in when you start the car, it may backfeed from the alternator and burn the unit. I'm currently investigating whether a controller will stop that, but I wish there was a way I could just hardwire this in and not worry about it. Installed on my dashboard using doubleback tape, incidentally.

I outfitted a kayak with a 12 volt electric system that included a GPS, fish finder, VHF radio, and a 35 pound thrust trolling motor. I'm using a 1000CCA deep cycle marine battery and a Sunforce 7 Amp Charge Controller with the SP200. Although it doesn't have enough output to fully charge a DOA battery, it does have enough to keep the battery charged. Indeed, I ran for ten hours yesterday, the first time I used the kayak. I used my meter to check the battery's charge before I left, and the result was 13.3 volts. Upon I return, the reading was 13 volts. So it functions perfectly! Remember two things: first, you must utilize a controller; and second, this is merely a trickle charge! Without the controller, the panel has no means of knowing if the battery is fully charged and runs the risk of cooking it!

In addition to driving a truck across the street, we have to have our own car parked at the corporate headquarters. We use our other car to move around after we come home and drive our truck there. We have to keep our 1998 Dodge Durango parked in Georgia for up to six weeks at a period because of this, and we never start the vehicle. When we do, we use it to go grab a bite to eat and then return to work, preventing it from being used long enough to fully charge the batteries. We bought this and the Schumacher SPC-7A 12 Volt Solar Charge Controller since we had to jump start our car after eight weeks of not using it. We place the solar charger on the dash and use thin window blinds with fairies on them. Even if it is not in direct sunshine, it charges quite fine. We put a multimeter on the battery after it had been parked for four weeks, and it read 12.3 volts and immediately started. We're debating getting another one for our car in Florida right now! I hope it's useful.
