Suunto D5 User Guide


Suunto D5 has a rechargeable lithium-ion battery. Charge the battery by connecting Suunto D5 to a power source with the included USB cable. As a power source, use a USB port of 5Vdc, 0.5A or a wall charger.

The battery icon at the bottom of the display shows the battery status.

For Suunto D5, the battery and charging notifications are as follows:

When you connect USB for charging and every time you press a button during charging, the following pop-up notification appears:

USB connected D5

When charging from a wall outlet, you will see the following screen:

Charging D5

In watch view and dive views (when on surface and during dives), a yellow 'Battery low' pop-up appears (see below) when there is less than three hours left from battery time. If you press any button, the pop-up disappears.

Battery low D5

When the time left decreases to two hours, a 'Recharge needed' red pop-up notification appears if you are on the surface. The red pop-up will stay on the screen on top of everything else and you cannot make it disappear until the device is charged or you change to time view. In case of scuba diving, when the charge level drops below two hours, you cannot start a dive with Suunto D5. For freediving, the limit is 30 minutes.


When the time left decreases to two hours during a dive, the red battery icon (see it in the table above) is displayed. The notification pop-up comes only on the surface so it will not cover information on the display during a dive.
