Battery health improving

[JulianY]

I never new about calibrating the battery until i came to the forum. I tend to use the power cord any way, being a programmer continuously running an edit compile and test cycle, my hard drive gets little sleep. Well having never done it i decided i would. Well when it returned istat reported 54 cycles and 93% health (16 month old). I also read the the battery likes to be used. so the the last few nights instead of shutting down at the end of the day, I just close the lid and unplug it, plugging it back in in the morning.

This morning i noticed istat reporting 97% health !

I am not sure what exactly health is , but this routeen defiantly seem to help

Is this a illusion or could this really be true? What exactly is health ?

Battery health is the percentage of the original battery capacity that can still be used. Let's say you have a battery with 6000mAh original capacity and your health is 80%, it means your battery's capacity is down to 4800mAh.

But, you do get free battery power..they come as 6900 mah batteries, but the first few weeks at least once they've bedded in you get a few extra hundred mah.
