John - 1) As stated above, if you only read 12 volts on the battery after charging, it didn't get charged properly. 2) 1.3AH isn't going to last long on a Climax. My Climax has a 4AH battery pack, and it runs for about 4 hours. So, I would estimate the current draw is near 1 amp. 3) The two 6V batteries: I assume you charge them independently at 6V? If you are trying to charge them while connected in series using a 12V charger, one battery may be getting more charge than the other.
