Age
Over a battery's life span, continuous cycles of depletion and recharging can reduce its maximum
capacity. A device which has been owned for many years is not expected to have the same
battery capacity as when it was new, regardless of amount of use.
The Typical Automotive Battery Lifespan,
and How to Care for the Battery in Order to
Maximize Battery Lifespan
A variety of factors - including locale, conditions/temperatures, and usage - will affect the
overall lifespan of a Garmin automotive device's battery.
Garmin's automotive devices contain Lithium-Ion batteries. Lithium-Ion battery lifespan is
negatively affected by exposure to extreme temperatures.
Garmin automotive devices should be stored in a temperature range between 32°F to 77°F (from
0°C to 45°C) when not in use to prevent permanent capacity loss. Devices should be operated
only in temperatures between -4°F to 131°F (-20°C to 55°C).
The lifespan of a device's battery may be permanently reduced if stored at temperatures above
77°F (45°C) for extended periods of time.
Cold temperatures (temps below 32°F / 0°C) generally will not affect the battery's overall
lifespan, though run time may be reduced temporarily.
Garmin automotive devices monitor the surrounding temperature and do not charge the battery
below 32°F (0°C) or above 113°F (45°C). These temperatures are required by the battery
