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?
Keep running it for a couple of days. You need to bring them up fully, and get the specific gravity up to 1.275 for each cell, or better, to 1.280. Is the pendant indicating it's still solid color green and in bulk mode?
It's going to be OK, just let it sit charged in for the weekend. Check the specific gravity with a specific gravity dipper, and write the readings down.
