The amount of charge a battery can hold gradually decreases due to usage
and aging. Specified to deliver a capacity of 100% when new, the battery
requires replacement when the capacity drops to below 80% of the nominal
ratingLithium-ion batteries lose capacity through cell oxidation, a
process that occurs naturally during use and aging. The typical life span
of lithium?ion is 2-3 years, whether the battery is used or not. |
