The *only* times I've ever needed a jump is first thing in the morning when I left something on over-night (heated mirrors, under-hood light). Hood light is gone, and heated mirrors stopped working so I unhooked them.
So really all I needed was a jump to get going, and then drove to work. Truck would start when it was time to go, and when I got home the charger would go on for a few hours just to top it off/desulfinate it. I think my automatic charger does a pulsing charge to help breakup build up on the plates (the desulfinating part) which has kept the battery going all these years.
I have one of these. I love that I can clip it on, hit regular battery, and let it go. It'll charge to 100%, switch to trickle charge, and maintain. Gives the voltage of the battery, and has an alternator test. Hell I use the damn thing to charge my Craftsman 19.2V drill batteries when they drop so low the factory charger thinks they're bad, and won't charge them!
I've avoided buying new drill batteries for a few months now (Sear's charger is 2 amp, small battery option on the SC7500A is 2 amp as well, so it works)!
The only thing I might do, is buy a larger model. This has a 75A starting mode, but that's not enough if the lights won't come on! It'll only do the 75A for a few seconds (or 1 start attempt) before going into a 130 second cool-down mode. I think one of the 100A or higher models would be better. At this point though if that doesn't work I hook up to the wife's Rav4.
