How to replace and calibrate the Apple Macbook battery

First post by: www.itsbattery.com
Last week I bought a new Apple Laptop Battery from the Apple Store to replace the slightly aged one that came with the machine. I'm travelling shortly and I need enough juice to play MAME and Doom do some work while I sit in airports waiting for connecting flights.
Late last week a parcel came for me, my new laptop battery! Here's how I replaced the old battery and calibrated the new one, with nice pictures.
In the mobile use of notebook, Latitude D610 battery life decide the notebook use time. As with lithium-ion Laptop Battery, in a non-normal temperature, the too high or too low temperature will damage the battery, so how does temperature affect the notebook battery?

A ,0-40 ℃ is the most reasonable working environment

When using the notebook, humidity, static electricity, temperature etc. have an impact on it, but the lithium-ion Dell D610 battery the most sensitive to temperature, the temperature too high or too low, the battery will bring negative impact to varying degrees, usually the limits of lithium-ion batteries for ambient temperature -20 ℃ ~ 60 ℃, and 0 ℃ ~ 40 ℃ is the most reasonable working environment, but to play the performance potential of Apple M8403 Battery, 20 ℃ was the best use of the environment around.

Second, It will reduce the battery life below -25 ℃

Although the laptop battery in -20 ℃ to allow the use of the environment, but that the PA3465U-1BRS battery will charge and discharge performance of a great general, the lower the ambient temperature, the activity of cell activity were lower electrolyte resistance and viscosity The higher the ion diffusion more difficult, not easy to charge and discharge latitude D600 battery.
For example, when the environmental temperature is below zero C1295, the battery charge-discharge efficiency will be greatly reduced, which will be very slow charging speed, full time electric power supply after only about 60% of the original, when the ambient temperature falls below the minimum temperature limit (for example -- 25 ℃), the battery electrode reaction rate is very low, even from the electrolyte freezing point, the latitude D600 battery performance may be only 10%, seriously affecting Apple M7318 Battery life.
III, The battery may explode above 60 ℃

With the low temperature case, if the laptop battery in high temperature environment, which will affect the battery's charge-discharge efficiency, but also for more serious damage to the Inspiron 510m battery, for example, or as a result of the use of inferior charger charging time is too long, making the battery 3R305 larger heat, When the temperature exceeds the maximum charge temperature limit, this will destroy the chemical balance within the cell, resulting in performance degradation of battery materials, to reduce apple PowerBook G3 Battery life.
The same reason, the battery during the discharge time, that is, when we use the notebook, due to internal short-circuit the battery or the battery design flaw, if the operating temperature exceeds the maximum limits, lower battery life receded, the situation will be serious emergence of the explosion, burning and so on.

The Macbook battery as (A1189 A1185,A1175) compartment is simple to open. Grab a coin, insert into the slot and twist.
Now, why couldn't they make the iPod battery as easy to replace? Phone covers can be removed to get at the battery and sim card so it's not a difficult job to do. There's an interesting iPod battery FAQ here. I expect this question applies to any Lithium Ion Macbook Pro 13 battery Apple PowerBook G4 Battery, not just the iPod's one.
Once I switched my Macbook on again my new battery was at 39% already and following the official Apple docs:

Charge the battery fully until the LED on the power cable goes green.
Leave it plugged into mains power for 2 hours. (doing that now)
Disconnect mains power and run the laptop off the battery until the machine goes to sleep.
Turn off the machine or let it go to sleep for at least 5 hours.
Plug the laptop into the mains again and fully charge the battery.
Tip: When the Apple PowerBook G4 15inch Battery reaches "empty", the computer is forced into sleep mode. The battery actually holds a reserve beyond "empty", to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, any open files could be lost. Therefore, it is important that you find an electrical outlet and connect the adapter before the forced shutdown occurs.

I wonder if calibrating your battery really helps? Has anyone done a controlled test over a length of time to compare two batteries?

I'm not sure why Coconut Battery reports that the "original battery capacity" was 5200mAh. Maybe that refers to my old battery? Please Notice this the tips can use in Apple A1012 Battery.
