Miracle workers or snake oil? If, in your opinion, it works, what do I need? Sources?
Picked up a charger with the desulfate function in it not too long ago. Tried it on a car battery that wouldn't stay above 12.5 volts for more than about 3-4 days.Miracle workers or snake oil?
To be clearMore work than its worth is what I found. I helped a friend do it.
In his case it made it back from 30% to about 75% of a new battery.
This was a deep cycle battery.
Thx, that ‘splains why its doing what it’s doing.FLA bats need cycling. Smarty is doing that.
SLA almost same
AGM no way. Let em go flat and game over, you will never recover any current.
I have to disagree with that. I have a AGM in my XS2. I left the ignition on for a week or so by accident or brain fade. Luckily the kill switch was off. The neutral light drained it flat dead. My chargers did not want to charge it. I had to hook another battery to it in parallel to it to get a charger to start working. After a couple of hours I could unhook the jumper battery. It took a couple of days and the battery was charged. That was 2 years ago. It's been fine ever since. I'm thinking of replacing it this spring because it's been in the bike for 4 years. It cam out of a parts bike I had bought so I really don't know how old it is.AGM no way. Let em go flat and game over, you will never recover any current.
Did the exact same thing. The parallel trick “fools” the charger into thinking it’s charging a healthy battery. I believe I had to get the voltage reading above 10v before I could unhook the second battery.I have to disagree with that. I have a AGM in my XS2.

I must tell my two AGMs that went totally flat, that.AGM no way. Let em go flat and game over, you will never recover any current.
My “smart” Optimate charger wants to see 2 or 2.4V to start charging a deeply discharged battery. The parallel trick is a good hack.Did the exact same thing.
