If the final capacity reading seems to be low (compared to the stated capacity of the battery), then the batteries in question probably just have an overall diminished capacity. If that's the concern (batteries not getting close enough to the desired capacity) you can always run them through the Refresh and Analyze cycle two or three times and then -- if necessary -- the Break-In cycle IF the Refresh and Analyze doesn't bring them back up to a good capacity. (The Break-In cycle can take a couple of days, though.)
I'm playing around with a few older sets of rechargeables right now trying to bring a bit more life out of them by running different combinations of cycles and seeing how they do. I have some older ones that I don't get much use out of since the capacity is so low that they won't keep anything operating long. I'm hoping to breath some new life into them with this charger. And if it doesn't work I'll know I can get rid of them and not worry about them any longer.
Whoa! I'd better revise what I said.
I think that you're right, kleng. It looks to me that when used in normal charge mode, what is displayed for MAH is actually the charge added. I don't think this is addressed at all in the user's documentation and most of the time that I've been using this charger (only about a month now), I have been doing just about everything but
normal charging -- so all I've been seeing are full capacity readings after completing whatever cycle I've been running.
But, after running a couple of standard charge mode tests, I see what you are saying.
So, it seems like after any of the other available modes are complete, what is displayed is the full capacity of the cell. But, if you use standard charging mode, what seems to be displayed is the added charge. That's sure what it looks like to me after testing.
