Suunto Ambit2 User Guide - 2.1
Charging the battery
The duration on a single charge depends on how Suunto Ambit2 is used and in what conditions. Low temperatures, for example, reduce the duration of a single charge. In general, the capacity of rechargeable batteries decreases over time.
In case of abnormal capacity decrease due to defective battery, Suunto warranty covers the battery replacement for 1 year or for at maximum 300 charging times, whichever comes first.
The battery icon indicates the charge level of the battery. When the battery charge level is less than 10 %, the battery icon blinks for 30 seconds. When the battery charge level is less than 2 %, the battery icon blinks continuously.
Charge the battery by attaching it to your computer with the supplied USB cable, or charge with a USB-compatible wall charger. It takes approximately 2-3 hours to fully charge an empty battery.
