Dead battery - ZR-1 Net Registry Forums

vilant · 02-02-2013

Last week when I tried starting it (it's been sitting for a couple of weeks), I got the clicking of a dead battery. I jumped it w/ another car (although after reading an old post after I did that, where someone fried there BCM, I'll never do that again) and she started right up, and I let it run for 15-20min. Figured I drive it around today and give it some exercise and maybe recharge the battery again. Unfortunately it wouldn't turn over berfore the clicking of a dead battery was back. I know the battery shouldn't be more than a few years old (at least the PO told it was changed recently), but the car has been sitting a lot before I got it and little bit recently. I've also been working inside the car, so the interior lights have been on more than they should have.I bought a battery charger and I'm trickle charging at 2A for @14hrs (charger recommendation, I also disconnected the battery leads, just in case).
My question is how to do you best preserve the life of your battery? At least for those who have to store their car for long periods of time (don't think LA or Vegas drivers have to worry to much about this). I'm not sure if just starting it, and letting it run, really charges the battery.
Or is just disconnecting the negative lead good enough?
Or do you leave it connected to a battery tender?
