PBG4 Battery

dpala1 · Mar 27, 2008

Finally got a new battery so i can use my laptop at uni.

But i notice that the battery never fully reaches the charge capacity (below info copied from about this mac - more info - power:

Charge Information:
Charge remaining (mAh): 5282
Charging: No
Full charge capacity (mAh): 5313

I've left it to charge overnight and it still hasn't reacher the full capacity. Is this normal. I followed the 'conditioning' instructions for new powerbook batteries.

That doesn't sound right. Did you get the battery from Apple, or is it a 3rd party supplied replacement?

yeah, it's an official battery.

I would ask for a replacement. At full charge, that battery should show that it's at capacity at this stage in its life. Try CoconutBattery for a second opinion - and if you're still seeing the same discrepancy, call Apple for a replacement.

I turned it off and let it charge for 10 hours.

Still the same:

Thanks for you help btw

I noticed that you lopped off the number of load cycles in your snapshot. How many does it say?

Five cycles

My bet would be that the battery sat in stock for a long time. I would call Apple and see if you can get an exchange. It should be under warranty yet.

Is it unusual that the battery has already lost 2% of its life, after 4 days of use?

Thanks

Absolutely, hence why I've recommended you contact Apple about an exchange.
