[AT] Batteries charged backwards.

[Cecil Bearden]

> I had 2 group 31 batteries out of the tractor that were completely 
> dead.  I hooked them up in series and connected my 24Vcharger to them 
> as It was handy and I wanted to charge both.  After a couple of days I 
> checked them and found that I had hooked the charger backwards.  I 
> hooked a couple of incandescent headlights to drain the battery, but 
> after 3 days they won't light up the headlights, but they still have a 
> lot of spark when shorted with cables..  A guy at my battery shop said 
> I should hook up a 6volt light to them and use that to run them 
> down....  At $100/ea, I need to try to save these...
