Three predefined battery modes – Performance, Endurance and Ultra – deliver from 25 hours to up to 120 hours* of recording time with GPS tracking on. When you start a recording, you’ll get an estimate of how much battery you have left with the current mode. If it’s not enough, switch to another mode at any time. On long ultra runs, battery life is often the limiting factor for recording distance and track accurately, as GPS is a heavy drain on the battery. Suunto’s unique FusedTrack algorithm combines GPS and motion sensor data to improve track and distance accuracy. This allows you to extend battery life by lowering GPS power without significantly compromising accuracy. Suunto 9 is designed and built to meet the demands of professional athletes.
