SUUNTO Vyper Air - Manual (Page 108)

Transmitter:
•
One 3V lithium battery: 1/2AA (K5546) and O-ring 2.00 mm x 2.00 mm (K5538)
• Battery storage time (shelf life): Up to three years
• Replacement: Every two years, or more often depending on dive activity
• Life expectancy at 20°C/68°F:
•
0 dives/year –> 3 years
• 100 dives/year –> 2 years
• 400 dives/year –> 1 year
The following conditions have an effect on the expected battery lifetime:
•
The length of the dives
• The conditions in which the unit is operated and stored (for example, temperat-
ure/cold conditions). Below 10°C/50°F the expected battery lifetime is about 50-
75% of that at 20°C/68°F.
• The use of the backlight and audible alarms
• The use of the compass
• The quality of the battery. (Some lithium batteries may exhaust unexpectedly,
which cannot be tested in advance)
• The time the dive computer has been stored until it gets to the customer. (The
battery is installed in the unit at the factory)
NOTE
Low temperature or an internal oxidation of the battery may activ-
ate the battery warning even though the battery has enough ca-
pacity. In this case, the warning usually disappears when the
DIVE mode is activated again.
