Why did you think they were gone? Just low voltage? And how did you conclude they were brought back to life?
I just bought something with a group 26 battery, 525 CCA, date 11/2010. Very very low voltage. Cells not low on water. Had to use manual charger for a few hours. Then Schumacher speed charger until it was listed as 100%.
Conductive check next morning showed 325 CCA and "battery bad".
The auto battery would not crank the vehicle it was in and the lawn mower battery would not in the lawn tractor. I charged them with a standard old fashioned charger and the auto battery would start the car but within a couple of days it would no longer crank the car. Did this over and over about 5 times. The lawn mower batter would not start the car even after a charge. I tool them both to AAP, O'Reillys, and Autozone to have tested and they all indicated they needed charging even though I had charged them. I let AAP keep and charge then retest and same result. I bought this charger and charged them wth it. The batteries each improved but were still not fully charged. Not sure what was wrong but after about four or five charges with this charger both the Auto battery was finally up to about 98% of capacity and the Lawn battery to 91% and each has worked without needinf any more charging since. Not sure what was wrong with them that they would not charge anywhere near capacity but this charger ended up getting them there.
The % you list, how is that determined?
It sounds like there is also a problem with the charging system in the vehicles.
I have a similar speed charger from Schumacher but it has not worked any miracles.
