I'd post mine but my battery has now got so bad that Coconut Battery crashes on opening.
I have a 6 month old MBP with less than 1% of its original capacity. If I unplug the power lead the computer will instantly turn off.

Only got this battery less than a year ago, since the old one ran out after 10/15 mins 
Though that lasted for around 700 cycles. This one lasts for like 40 mins, I need to get myself a new one soon... again.
I don't understand why my capacity has done down so much though?

Macbook 2006
I have got too say that this is actually very decent for a 40 month old machine. It has been in daily use and I´ve never replaced the battery. I was told once that the batteries were made to last around 500 cycles..? I still have 3-4 hour use-time, ofcourse, not when I watch movies and stuff.
And to the guy who said he always drained the battery completely before recharging; Lithium batteries like it best when they can be re-charged when they are at 30-90 % of capacity. Do NOT drain fully.

It's actually 300 cycles for an laptop average. Basically what it means is that the battery will, and should last at least 300 cycles and still maintain 80% health. That's just a standard marker, not an actual thing that has to happen.
Here's mine on my MacBook Air. Yes, I do use my battery a lot, it's gone through over 500 cycles just over 7 months since purchase.

Notebook batteries consist of individual cells,such as a 6-cell battery.
Is there any way to estimate the overall capacity of a notebook battery from the number of its cells? How much capacity does such a cell typically have?
When selecting a notebook battery,such as hp pavilion dv6000 battery udtekHP/Compaq Pavilion DV6000 Battery 12-cells 8800MAH Description:
Cell Type: Li-ion, 12-cells
Voltage: 10.8V
Capacity: 8800MAH
UL certificated cells inside!
http://www.udtek.com/hpcompaq-pavilion-dv6000-battery-12cells-8800mah-p-20875.html
manufacturers will often list an amount of cells, where each cell has a certain capacity; thus a 9 cell has 50% more capacity than an equal model 6-cell battery. That is useful for comparing directly, but the story is more complex if you wanted to compare different batteries on different laptops. Batteries have a voltage rating (V) and milli-Amp hours (mAH), which, if multiplied together, give you milliwatt hours.
For example, a 14.8 V battery with 4460 mAH gives you 66,000 milliwatt hours (66 watt-hours). You can compare laptop batteries this way, but also keep in mind that different laptops have very different power requirements that vary based on the components and how well the operating system manages power consumption. Typically, bigger, heavier batteries will give you a higher watt-hour rating. A 6-cell battery may be the same form factor as a 9-cell, but the 6-cell will weigh less since theres less chemical in it to hold onto that charge.
If you are a mobile warrior, you will want the most cells and/or most watt-hours you can get into your model so you can go 5 or 6 hours without a recharge. It is so painful to run out of power before you are ready. And here I suggest you a online-shop to buy good notebook batteries.My friends have bought from udtek.com .There are many computers hardwares on udtek.com. She thought its a good service , fast shipping shop,and high quality shop.May be its good idea for us to see what products we need .
Nice ad, however, Apple batteries don't use cells. They are custom shaped design battery "cells"
