Dear Tom
Thanks for your patient. OK, I will follow your instruction, continue to charge until 16.2V and discharge to 12.2V. I will see what kind of improvement I can have. It is quite frustrating to see no improvement after 11 cycles.
Is the 14.5V resting voltage, terminating voltage or voltage just before SSG stops? How did you calculate 80% depth of discharge is between 12.2 and 12 volts? And also how did you calculate 13.2V is only 65% of charging?
Best Regards
1- your junk battery will not go that hi probably, on the SG it will stop where the sulfation will no longer come off the plates. i did not expect to see improvement of your battery at all given how it has been treated. stop wasting your time with that thing. if you want to desuphate it crank the current up on the primary and blow the sulfation off the plates. its the pulse that cleans the plates and dissolves the sulfation. you will not have over unity at ALL but your capacity may come back, maybe !! you cannot expect increased capacity or faster charging with a junk battery.
2- do you have the manufacturers specs for your battery? read them and use them as a basline for YOUR battery. 14.5 is the charge termination voltage usually from the manufacturer but it VARIES by manufacturer. your batteries might be good at 15.3 not 16.2 as John K has said. its DIFFERENT for every battery. Peters batteries were deep cycle Golf kart style 6 volt cells.
3- by running a battery charged to 13.2 on my CBA and comparing it to what its capacity should be. often times a battery will sit at 13.2 for a very long time as it fills up. you need to research charge curves for batteries to see what they look like.
its all about the battery....... the machine performs based upon what it is hooked to, its not magic. learn the theory of operation, then learn about lead acid batteries and then you will answer for yourself your questions, it will be obvious why the battery wont charge up fully.
