Guidelines for prolonging Li-ion battery life
* Unlike Ni-Cd 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 Ni-Cd batteries.[7]
* Lithium-ion batteries should never be depleted to below their minimum voltage, 2.4v to 3.0v.
* 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.
* According to one book,[12] lithium-ion batteries should not be frozen (should not be stored below -40 °C), because most lithium-ion battery electrolytes freeze at approximately −40 °C (this is much colder than the lowest temperature reached by household freezers, however).
* Li-ion batteries should be bought only when needed, because the aging process begins as soon as the battery is manufactured.[7]
* When using a notebook computer running from fixed line power over extended periods, the battery should be removed and stored in a cool place so that it is not affected by the heat produced by the computer.[7]
