Question about new iBook battery

[pistooli]

I have purchased a new battery for my trusted iBook. However coconut Battery gives me the following information after the battery is installed (see pic).

Current battery capacity 95%??? It is a new battery, as loadcycle count is 1.

Is this correct, any it will reach 100% after a couple of carges?

Thanks for your reply and advise.

Battery's can lose there full capacity just sitting on a shelf waiting to be sold. Being iBooks have not been made since 2005 this New battery may have been on a shelf for 3-4 Years waiting to be sold. 95% is still very good

Thanks you for your answer. I was thinking about something similar. Well, this is what I have to pay for using my beloved iBook, then.

Did you calibrate your new battery?

 

[pistooli]

and after two days its only 85%... I doubt it is ok.

 

[pistooli]

Did you calibrate your new battery?

if you mean by calibration that I fully charged and then drained, then yes, I am doing it for the second time... but now it shows only 85% health. no good.

Where did you buy it? Can it be exchanged?

I don't know why I even bothered to write anything, since I'm obviously so incredibly wrong about Lithium Ion batteries and calibration cock-ups. Oh I do apologise, may your further calibration of these batteries work wonders for you in the future so that Apple can continue to rake in your money when the thing dies and isn't covered by your warranty because you're the one who killed it.

Calibrating the battery should only be done once on rare occasions, if at all, and even then only if the charge is severely reduced below that of what it should be. Since yours was reading 95% I'd say, as someone else mentioned, that was normal considering the average degradation that would occur to the cells over time anyway.

Calibrating it at all when it was reading that high has probably done more damage than it has good, hence why it's now reading 85%.

you're wrong. Apple recommends calibrating once a month. He did not hurt the battery by calibrating. Cycling your battery is normal.

 

[Xandros]

See above.

I'm not wrong. Apple does indeed recommend this ******** routine and idiots blindly follow it as if it's gospel truth, and they're fools for doing so. Their "expertise" are throw backs from before the days of Lithium Ion batteries, when calibrating actually made a difference to batteries that had suffered from capacity "memory". LI cells can go into deep discharge if you empty them out, and it can royally **** them up (of course Apple doesn't care if you kill your own battery, chances are you'll do so after the warranty's ended).

Another fallacy. These batteries have a small circuit inside them, that prevents harm done from the calibration.

Ouch, why are you so insulting? We are to just take your word for this, with nothing to back it up? In January of last year, I replaced the battery in my iBook, with an off brand, and followed the instructions. So far it is holding up very well.

 

[pistooli]

I did receive instructions for the new battery, and it clearly said, to completely discharge it 3 times for the first 3 usages - like in good old Ni-Cd and Ni-MH days. I also believe that this battery has a circuit to prevent complete discharge, so no demage is done by doing it.

Lets see, what happenes now.

----------

Where did you buy it? Can it be exchanged?

Probably. It has 6 month warranty. I shall see what happenes now, and then make an inquiry with the supplier.

 

[pistooli]

I think it is time to ask for a replacement. 84% now, 3rd cycle count.

 

[Xandros]

See above.

irrespective of calibration - cycle count of 3 and 15% lower than rated capacity = you were not sold a "new" battery.

how long the vendor had it on the shelf is irrelevant. if it isn't in "new" condition it shouldn't be sold as a "new" battery (maybe as "Clearance stock" or "as is" but not "new"). shelf time is a vendor supply chain issue - not your problem.


live with it, or take it back - if you can weaken a battery that much after 3 cycles of use, calibrated or not, something is wrong with it.

thanks, I was thinking the same. I already contacted them, and they will take it back.
