In technical terms, you probably have a "sulfated" battery.
In car sizes, 5 amps for 24 hours should get it charging in the
right direction. Smaller battery, less current. It will take a
while. You will be forming the battery, giving it its initial
charge.

Go for it.

Thanks for the advice.
I fixed the charger and re-reversed the batteries. One scooter seems to
be working fine. The batteries seem to be ok on the other one, but
somebody ran it with insufficient air in the rear tire and hurt the
inner tube. Won't hold air long enough to give it a good test.
