• 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 –> 2 years
• 100 dives/year –>1.5 years
• 300 dives/year –>1 year
Transmitter:
•
One 3V lithium battery: 1/2AA O-ring 2.00 mm x 2.00 mm
• 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 quality of the battery. (Some lithium batteries may exhaust unexpectedly,
which cannot be tested in advance)
• The time the transmitter has been stored until it gets to the customer. (The battery
is installed in the unit at the factory)
