I am involved in a major project on the boat involving moving the house bank (adjacent to the previously discussed ER vent), attaching it securely to the vessel (including rollover security), sealing the battery box and venting overboard, relocating the Trace, and moving all the involved wiring.
I will attempt to re-calibrate the AH meter at that time. The manual for the AH meter stated that the meter will automatically zero itself when it sensed the battery was fully charged. Perhaps the fact that I had some bad cells threw it off. In the future I will be a good boy and record the AH meter reading whenever I do hydrometer measurements to get a written correlation. Thanks for all the great info, insight and suggestions.
