Battery Information
Your unit contains an internal (non-removable) lithium-ion battery. Contact your local
waste disposal department for information on properly disposing of the unit.
Battery Tips
• Your nüvi’s battery should last 4 to 8 hours depending on usage. The battery
gauge indicates the status of the battery.
• To extend the battery life, reduce the time the backlight stays on. From the
Menu page, select Settings > Display > Backlight Timeout to change the
setting. See page 40.
• To extend the battery life, close the antenna when you do not need to receive
GPS signals.
• To increase the accuracy of the battery gauge, fully discharge the battery and
then fully charge it. You should not need to do this very often. See “Battery
Gauge” in the side bar for more information.
• To maximize the life of the lithium-ion battery, do not leave your nüvi direct
sunlight and avoid prolonged exposure to excessive heat.
Battery Gauge
The battery icon in the upper right corner of the Menu page indicates the status of the
internal battery.
