I haven't been driving my electric Geo that much because it gets really hot in Oklahoma during the summer, and putting A/C back in is a challenge. I do need to drive it occasionally to keep the batteries exercised. To that end, I drove it about 3 miles a couple days ago. What is interesting to me is that the only new battery in the pack took a VERY long time to charge. I find this very odd. The other batteries took a few hours, but the new one took over 12. Also, I decided to treat one of the batteries in my pack with the ECO2 battery reviving product I received from Korea. I treated the battery that showed the lowest voltage after the 3 mile drive: it showed 12.11 volts (the other ranged in voltage from 12.22v to 12.73v after the drive). I also connected the electronic battery desulfator to it.

Batteries are a strange animal, I have lived off the grid for 15 years and have learned some. If you have a bank of used batteries and add 1 new battery to them, the efficiency of the new one degrades to the point of the old ones. It also sounds like you are using standard car batteries, they NEED to be Deep Cycle, and matched ( same kind ,size, even same date of manufacture). All these points affect how well they get charged. More important than checking voltages is to check the specific gravity of each cell. You can get a SG tester at any auto store,cheap! It'll tell you the most. Good luck!
