best way to treat a Li-ion battery notebook?

# Unlike NiCad 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%. Lithium-ion batteries should never be "deep-cycled" like NiCd batteries.

# Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly.

# Lithium-ion batteries should never be depleted to empty (0%).Li-ion batteries should be bought only when needed, because the aging process begins as soon as the battery is manufactured.When using a notebook computer running from fixed line power over extended periods, the battery can be removed and stored in a cool place so that it is not affected by the heat produced by the computer. (However, a notebook computer's battery prevents sudden loss of the data in memory during power failures and brownouts. Reasonable alternatives are the use of an older lithium ion battery or an external uninterruptible power supply.)

usually it is best to run it close to it last mileage before recharging

but we know it doesnt happen ideally all the time

so when you are at home...change settings to start recharge at a lower % and use electricity

There is no need to top it up all the time as it may reduce your battery life and health...

Take it off if you use it plugged
