A lithium-ion battery is used in many laptops and other electronic equipment. In order for one to function properly, however, certain techniques have to be utilized. This is particularly true when the battery is new, during the breaking-in phase. Lenovo knows its batteries from the inside out, and offers tips on how to correctly uses its lithium-ion batteries.
When a battery is new, it should be charged fully before use. This activates the chemicals inside, assuring a deep cycle charge. Do not charge it just a little bit, thinking the charge is good enough. You must leave it on the charger until the indicator light states the battery is ready to be used.
No Deep Discharge
Nickel-metal-hydride batteries should be deeply discharged before use, but Lenovo states doing this to a lithium-ion battery will destroy it. Therefore, never deeply discharge a lithium-ion battery, but rather plug it in the charger when not in use. This keeps it fully charged.
Lithium-ion battery packs are not sealed watertight. They should not be used in high moisture areas, such as on a boat. For saltwater environments, the salt-laden moisture in the air will corrode out the battery from the inside out. If you must use a battery pack on a boat, remove it to a dry location as soon as you are done using it.
Avoid Temperature Extremes
Boston College recommends avoiding temperature extremes. In the winter, do not leave your battery in a cold car. In the summertime, do not leave your battery in a car with rolled-up windows. Temperature extremes degrade the chemicals in a battery, reducing its life span.
