My question is in the quality tester circuit to use another meter other than 660ua would I only change R10 or would I have to also change R9 ? I have 220ua and 250ua meters.

just curios, is it possible to detect _shorten_ cells in car battery? had my battery dead this way previous year (2016). battery was almost new, but as i discovered after, one of the cells had lack of electrolyte, what caused it to dry, crumble, and short-circuit. if i try to connect this "quality tester" i propably will see even a "better" quality, due to less internal resistance of 5 cells than 6 cells

Lamazoid. Possibly, but Just a Volt Meter should tell you that one cell is dead. 12.6 is normal. 10.5 if one cell is totally dead.
Kiloamp. R10 Should do it, But could change Both.

Thanks Gary I'll try R10 first and see how it goes.
Lamazoid, I hope you got warranty on that battery, it sounds like a manufacturing flaw.With anything produced in mass production there will be some that are not perfect

Lamazoid, I hope you got warranty on that battery, it sounds like a manufacturing flaw.With anything produced in mass production there will be some that are not perfect it's happened on 31th december, 2016. the New Year.... warranty? everyone here was already too drunk to think about warranty at that moment i've just carried it to junkyard next day... BTW, my friend works in mercedes-benz authorized service, they have some kind of "smart tester" for batteries, which performs testing for hour or so (!). the result is simple "OK" or "CHARGE" or "REPLACE" , but algorithm is very complicated, many things are checked. I'll try to figure out more about it.

Thank you Gary,.. I will check out your New High Current Desulfator tonight!

it is said that "This Desulfating Process, "May take a LONG TIME"." how can we determine when it ends? by resistance meter readings? also, can we speed up the process by increasing the amplitude of voltage spikes?

You Can't really determine When it ends, other than watching for changes in the Meter Reading. The Horizontal Mounted Trim-Pot Determines the Strength of the Pulses. I Recommend setting this one at About 50% Rotation. Increasing it too much will Create Higher Current Pulses, But will also cause the battery to Charge Up Too HIGH in Voltage. The Vertical Mounted Tri-Pot on my circuit Determines the Reference, Meter Reading. Set This one, After you have set the Horizontal Trim-Pot. When or If the reading goes LOWER, it Indicates the batteries Internal Resistance is also going Lower. This would be Good. Do NOT Change the Strength of the Pulses without Re-Setting the Meter, or the Meter Readings become Useless.
