Guidelines for prolonging Li-ion battery life

[eyesontech]

Unlike NiCad batteries or NiMH batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a longer time, they should be brought to a charge level of around 40%. Never use the battery care functions some cellular phones provide for nickel based batteries. (This will deep cycle the batteries.)
Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. However, they should not be subjected to freezing temperatures. Aging will take its toll much faster at high temperatures. Keeping them in burning hot cars can kill lithium-ion batteries.
Buy Li-ion batteries only when needed. Look at the manufacturing date. That is when the aging process commenced.

When using a notebook computer running from fixed line power over extended periods, it is advisable to remove the battery and store it in a cool place.
However, many laptop manufacturers recommend against removing the battery from a laptop while it is plugged in, as this can damage a laptop designed to operate with the battery installed. Some manufacturers are also concerned about dust accumulation with the battery removed. Therefore, check the manufacturer's instructions before removing the battery.

I think exposing the laptops to heat is something that we all know is most damaging to the battery . Second thing is that do not charge the battery when there is already half of the battery remaining as it lowers the life of the battery , so think twice before leaving the laptop in your car on a hot sunny day .
