1.4 CHARGING THE BATTERY
Suunto M9i is equipped with an internal rechargeable battery. You can recharge the
battery approximately 500 times. The life expectancy of a single charge depends on
the use of the GPS, Compass and data storage functions. When the battery level
indicator on the display reaches the red zone, the battery voltage is low. When this
occurs, you should recharge the battery. However, extremely cold weather affects
the battery voltage even when the battery is still fully operational.
If the battery warning indicator is activated in temperatures above 10°C (50°F), recharge
the battery.
Do not attempt to change the battery, as this will void warranty. Take the Suunto M9i to
an authorized Suunto dealer for a battery change.
You can charge the battery with either the included mains charger (universal mains
voltage) or through your PC’s USB connector. For other charging options see
www.suunto.com.
Charging the battery with a mains charger
To charge the battery with a mains charger:
1. Plug the charger into the mains outlet and attach
its data clip firmly to your Suunto M9i.
2. When the battery level indicator is full, discon-
nect the charger from the mains outlet. Your
Suunto M9i is now ready for use.

connector
To charge the battery through your PCs USB
