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.
