Conditioning a New Laptop Battery

This advise applies to either a brand new laptop, or a replacement battery.
As the owner of a new laptop there is one problem for certain that you will encounter at some point in time, a depleted or worn out battery, particularly so if the laptop is often or primarily connect to mains power. Eventually the battery will wear out and the run time when disconnected from mains power will gradually decrease over time to the point that the laptop will often run only a few minutes when running on battery. You may even receive a waring on screen sometime that the battery is depleted and needs to be replaced.
Replacing the battery is fairly straight forward but there are a few precautions to take to ensure a good lifespan from the new investment of a replacement battery. Following the advice below will ensure you get the most out of your new purchase. The first piece of advise is the hardest to swallow but you will benefit greatly from it:
Turn the laptop off and unplug it from mains power. Insert the new battery and plug the mains power back into the laptop but DO NOT turn the laptop on yet. Let it charge fully overnight before first use. This will be the hardest step as most users are anxious to use their new purchase.
Once fully charged disconnect the mains power from the laptop and turn the laptop ON and let the battery drain, this may take several hours with a new battery depending on the capacity of it. You can of cause continue to use the laptop whilst the battery is draining and this will help the battery drain faster.
Once the battery is drained, plug in the mains power to charge it again and repeat this process 3 times (drain the battery fully, charge it fully 3 times).
By following the simple steps you will ensure you get the most from your new purchase and a greater lifespan from the new battery.
These simple steps can also be applied to the purchase of a brand new laptop, as the manufacturer never conditions the battery before shipment. New batteries are only shipped with approx. 60% to 80% charge in them.
Another good point to remember is if you are storing the battery for any length of time, make sure to store the battery fully charged as lithium polymer (LiPoly) batteries become unstable when depleted.
