over the last year, i've accidentally let my battery drain down pass the point of enough juice to start my truck mostly because i'm drawing so much electricity from my stereo system. i did it again last night so later on today i will be installing an Optima Yellow Top battery in my truck. from my experience, if "regular batteries" are drained all the way down more than a few times, it never seems to perform the same after that. i don't want to be somewhere in zero degree weather and my truck won't start.
plus, if someone asks me for a jump start, i have to politely tell the "no" because i've heard too many horror stories about someone's electrical system getting trashed or having to replace their computers in their trucks because of jumping someone's auto. so if i have a booster with me at all times, i can quickly assist someone in trouble without subjecting my truck to harm.
i have that exact same one behind the seat in my truck. i like it, it works for everything i've used it on. i've never had to jump start my truck but i have jump started a dodge cummins and saturns and my fourwheeler and its worked good so far.
I have a Sears Diehard 750 and like it. Same thing I have jumped the lawn tractor and quad, and a friends car. The thing seems to hold a charge forever. I just went deer hunting for 10 days. I threw it behind the seat of my truck, just in case. It had been sitting all summer in the garage so I figured it would be low. When I went to charge it up it was still at max charge. I think you could probably jump several vehicles with one charge. Anyway I am happy with mine. About $45.00.
I guess they could work. But how effective? Who knows. I wouldn't depend on that panel for a jump start. But it can't hurt if you've got good exposure to sunlight for a full day at a time.
I was thinking since the truck only gets used once a week, that it would be a good "battery tender" to help offset the parasitic draw that gets pulled from the battery. I am not sure where this much draw is coming from, but I have a lot of electronic crap in the truck that is on stand by even when shut off...like the satellite radio, TV screens, Alarm, door solenoids, etc.
