I installed a new progressive dynamics converter with charge wizard today. I checked the date on my batteries and they say A9, so I assume they are 5 years old. After putting them on the charger for only 4 hours they are holding a 13.1v charge. I have not equalized them yet. My batteries even with the wfco charger have always been good to me. I can run my furnace all night even in the poor state they are in now. When do I know if it's time to switch them out?
