At a 100% charge level, a typical Li-ion laptop battery that is full most of the time at 25 ?C or 77 ?F will irreversibly lose approximately 20% capacity per year. However, a battery in a poorly ventilated laptop may be subject to a prolonged exposure to much higher temperatures, which will significantly shorten its life. Different storage temperatures produce different loss results: 6% loss at 0 ?C (32 ?F), 20% at 25 ?C (77 ?F), and 35% at 40 ?C (104 ?F). When stored at 40%?60% charge level, the capacity loss is reduced to 2%, 4%, 15% at 0, 25 and 40 degrees Celsius respectively
