Battery Tips
Tip 1. Avoid excessive heat and cold
z
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).
z
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.
z
Allow unrestricted airflow while the computer is connected to external power. Make sure that the
fan inlet and outlet are unobstructed.
z
Avoid exposing batteries to hot or cold temperatures for long periods.
How your battery behaves in warm conditions
z
To prevent possible damage to the battery, the system may not allow a charge if the battery
temperature is above 122°F (50°C), such as in a closed, unattended vehicle during the summer. In
this case, the Battery Power Indicator may indicate that the computer has stopped charging
your battery; however, your battery may not be fully charged.
z
If possible, turn off or suspend your computer while the battery is charging in a warm
environment to avoid over-heating.
z
In warmer temperatures, your battery may take much longer to fully charge.
How your battery behaves in cold conditions
z
When using a battery in cold conditions, the battery capacity may drain significantly faster.
z
To prevent possible damage to the battery, the system will not allow a charge if the battery
temperature is below 41°F (5°C), such as in a closed, unattended vehicle during the winter. In this
case, the Battery Power Indicator may indicate that the computer has stopped charging your
battery; however, your battery may not be fully charged.
z
In cooler temperatures, your battery can take much longer to fully charge.
