Battery
• One 3 V lithium battery: CR 2450 (K5597) and O-ring 1.78 mm x 31.47 mm
70 ShA (K5664).
• 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/y  2 years
• 100 dives/y  1.5 years
• 300 dives/y  1 year
The following conditions have an affect on the expected battery lifetime:
• The length of the dives.
• The condition in which the unit is operated and stored (e.g. temperature/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 audible alarms.
• 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 into the unit at the factory.
NOTE Low temperature or an internal oxidation of the battery may cause
the battery warning even though the battery has enough capacity.
In this case, the warning usually disappears when the Dive Mode
is activated again.
