Trick of COP calculation

you can discharge to whatever you want..... its your battery you are destroying. the CBAIII has no idea what the cutoff should be. I have a cba IIII it has all the variable for discharge. I suggest you contact the battery manufacturer and ask them what the cutoff voltage should be. you are destroying your battery. of course it matters if your battery is junk when doing sg cycles!!. if you are rejuvenating that battery, then a charge discharge cycle is all you need, no cop calculations. rejuvenation is not over unity, ever!! you will not get hi cops with a junk battery, all the energy is being used to desulphate.
you are not fully charging your battery if you are only going to 13.2 thats only about 65 percent. the fully charged cutoff voltage for a battery is around 14.5 if you read the manufacturers spec of most batteries. peter lindemann in his battery secrets lecture talks about how he likes to see them at 16.2 because that is where ALL the material is returned to the plates where it belongs and where the battery simply becomes a hydrogen generator. you are wasting time trying to rejuvenate it if you are discharging to 10.5 that is undoing anythng the SG may be doing to restore the battery. 80% depth of discharge is the max you want to run a lead acid battery at which is between 12.2 and 12 volts. batteries are like a living plant you gotta tend to them the way they are designed or they will die. you wil be frustrated with your results if you dont learn about the battery first. use the go advanced button when you post to attach something.

When you said 80& of DOD, it means to be discharged 0.8x7.2AH (capacity of battery)=5.76AH out of battery at 0.36A (C20 rate), am I right?
