Is this normal? I've just recalibrated the battery and the result is the same...

Thanks, Mike

Back to my old 2.2GHz C2D MB after selling my MBP and wondering what my next Mac will be :)
Mine's better :D



Seriously though, no it's not overcharging.
Some new batteries come with a little more, and some come with a little less charge.

Be happy that you got one of the good ones :)

It's all in the math. Like "6string" mentioned...all batteries are not the same. When new...some batteries have a slightly higher amount of mAh's & some have slightly less. In "6string's" example...his battery has a design capacity specification of 6900mAh...but his battery has a current actual capacity of 7020mAh (120mAh higher than the design spec.).

It's possible that a battery has a 100% capacity specification of 6900mAh...but batteries from the factory may actually range from 6750 to 7050...so +/- 150mAh.

Now you take the program "Coconut Battery". It has some sort of table in it's program that says "6string's" battery at 100% charge is supposed to have 6900mAh...but in reality (when the battery is fully charged) it has 7020mAh. So if you do the math...that works out to be 101% of the original design specification.

HTH,

p.s. Technically speaking...a battery with a design capacity of 6900mAh...but an actual 100% charged capacity of 7020...is at 101.739% (almost 102% if you round it up)!:)

Couldn't have said it better :)

Also, now that you know, forget about coconut battery, smc fan control, and any other junkware that you may do your head in over, as this will only take away from you enjoying your Mac as it was designed for you to do :)

I think you did say it better (short & sweet) when you said..."Some new batteries come with a little more, and some come with a little less charge."

I just gave the long version!;)
