How to Rescue a Petrified Battery

[Joe C.]

Hello all,

I recovered a "Group 24" battery from a 18,000 mile, 1992 Honda Accord, and would like to know if I can use this as a spare, or if I should return it to WalMart and collect my $9.00 recycling deposit.

The battery is a "calcium/lead-acid" sealed type.
It was put "in-service" in January, 2002.
The Honda has not been used since March, 2003.
Battery tested "stone dead" at zero volts, yesterday morning.
It has been on 10.0 amp charge since yesterday morning, BUT WILL NOT DRAW MORE THAN 1.0 AMP CHARGE RATE AT ANY TIME, MOST TIMES DRAWS LESS THAN .5 AMP.
Is this battery too badly sulfated from it's extended state of discharge to be made usable?
Thanks in advance.

Joe

Joe,
A few years ago I bought a Battery Minder Plus at Carlisle.
It claims to help condition and reverse the sulphation process in lead acid batteries.
I have used it on a few weak batteries which would not charge properly and it did seem to bring them back to life, one for over a year of subsequent use.
Sometimes you have to leave it on a battery for 3 or 4 months but it does seem to help.
