When I parked it I pulled the 2 6V batteries (which were wired in series) and put one of the batteries on a trickle charger I use for my car and motorcycles. Unfortunately I charged ONE of the 6V batteries at 12 volts for about 12 hours before I discovered my mistake, then switched it to 12V.
Did I ruin this battery?
I correctly charged the other battery at 6V.
What you did is actually a little trick that is good for the batteries. Ive used a 12v battery tender on 6v batteries to act as a poor mans equalization charge. Posted a thread on it here.
1. Did you check water level before charging?
2. Did you check voltage before charging? (what was it?)
3. What charger did you use to charge the single 6v battery?
Im guessing you might have wired them back in series, and then attached the battery tender to both batteries. That gets a little tricky because the individual cells are not balanced.
If they were my 6v batteries i would use your battery tender again. Charge them individually like you accidentally did before. But this time you have to be smart and careful. Charge them outside because they release a gas. You also need to be home so you can monitor voltage. If you have a 5a 12v battery tender that will work pretty good to bring life back to damaged 6v batteries.
