Battery Tips

Tip 1. Avoid excessive heat and cold
Your battery will last longer during the day if it is used, charged and stored between 50°F and 86°F (10°C and
30°C)
Charge the battery nightly where the temperature will remain around 68°F (20°C). Your battery may not last
as long through the day if you charge it at higher or lower temperatures
Allow unrestricted airflow while the computer is connected to external power. Make sure that the fan inlet and
outlet are unobstructed
Avoid exposure to extreme temperatures for long periods, which can shorten battery charge life and
potentially damage the battery.
