The battery on Jen's Boss 302 is Stone dead. I should of put the trickle charger on it last year but it's in a remote garage and it became an out of sight, out of mind situation. That being said, I put the trickle charger on it today. The battery is 2 years old. Do you think there's any hope of it bouncing back? I thought I read somewhere that charging up a dead battery slowly is better. I was going to leave it on the trickle charger till Monday and see what it reads on my dvom What say you?
Keep in mind, trickle chargers won’t turn on a completely dead battery. It needs to sense that it’s connected to a live battery
We at the store hook a live battery with jumpers to customers completely dead batteries to start the charging process
Some chargers have a desulfation mode that can bring stone dead batteries back from the dead. And don't get me started on battery chargers that won't charge a dead battery. I have an ancient Sears charger that I have to hook up for a few minutes to put a few volts in before the new "SMART" charger knows there is a battery there.
AGM or FLA battery? Both stand a chance, but an FLA stands a better chance. Voltmeter is very limited into how to judge how good a battery is. Plenty of choices for inexpensive carbon piles for < $100
I leave it on bake till Monday and see where we're at. It's a 2013 with I think a little over 11k on it. I think the last time it was out was a year ago
Funny thing today I had this problem and I got an old school sears charger from my neighbor to kick start a 2 amp charge on each battery and now I have the regular golf cart charger working. The charger would not work when they were all completely dead. Like Jason I hope I can pull some more life out of these batteries as they are only 3 years old.
I've had several dead batteries with less than one volt come back to life and last for years. Charged them with my old Craftsman 6 amp charger for a few days.
When I called Schumacher about why their "smart" charger would not charge a dead battery their response was usually battery is not totally dead. Well...if you leave something on for a week it will be! Or any kind of slow drain for a long time...... Then he said disconnect battery when not in use. Well yeah.....I suppose....
I've got one of these and it's the only charger I've had that will bring back a completely dead battery.
