Poseidon SE7EN+ User Manual Chapter 1 Page 7
The Learn Cycle Activation Button: Just above the Learn Cycle indicator light is a button.
Pressing the button will manually initiate a Learn Cycle. It may be pushed at any time during a
regular charge cycle to initiate a Learn Cycle.
The System will require a Learn Cycle if the smart battery is fully depleted; if it has been
more than 90 days since the last Learn Cycle; or if the cell has had more than 20 charge
cycles since the last Learn Cycle. The system will recommend a Learn Cycle if it has
been more than 45 days since the last Learn Cycle or if the cell has had 10 or more
charge cycles since the last Learn Cycle.
Charge Cycle Indicator Light: The right-most light on the charger is the charge cycle indicator,
and it has the following meanings when plugged in with the smart battery inserted:
• Off: The battery is being discharged as part of a Learn Cycle.
• Alternating Red and Green ashing once per second: No battery detected.
• Both Red and Green ashing: Battery is being charged (more green as battery is charged).
• Red continuously on: Charging has failed (may require a Learn Cycle).
• Green continuously on: Charge cycle completed successfully, battery is fully charged.
While charging, the light will ash rapidly when the battery is discharged, and will ash more
slowly as the battery becomes more charged. As a general rule of thumb, 1 minute on the
battery charger in standard charge cycle mode will load 10 minutes of charge into the battery.
Thus, if you charge while taking a 30 minute break between dives, you will have added 5 hours
of dive time to the battery.
Leaving the Smart Battery in the Charger: Although it is acceptable to leave the smart
battery in the charger when not in use, it is recommended that the battery be left attached to
the Poseidon SE7EN+ after a successful charge for the following reasons:
• If power to the charger fails at any time, then having the battery in the charger will actually
deplete the cell – approximately as fast as if the battery was installed in the rig and the rig
powered up.
• Storing the battery in the Poseidon SE7EN+ reduces the probability of debris entry and
impact damage to the battery contacts in the electronic module.
• Storing the battery in the Poseidon SE7EN+ enables the depth sensor and the wet switch
on the back of the primary display. If someone wearing the SE7EN+ accidentally falls into
the water, the system will automatically power up the rig, enhancing the probability for
survival of the user. This is only possible if the battery is charged and stored in the rig.
Long-term storage
Allowing the smart battery to sit for long periods of time on-shelf without recharge will lead to
premature failure of the battery. The best storage method, if the battery will not be used for a
substantial period of time, would be to top off the charge once a month by running it on the
normal charge cycle in the desktop charger. If this is not possible, then the best long term
solution is to leave the battery on the charger (with the power to the charger turned on). The
method of monthly top-off of charge, however, will maximize the battery life. Store the battery
in a cool, dry environment.
WARNING:
A SE7EN that is powered down with a battery installed will
power up and enter dive mode if it detects a signicant water
depth. Likewise a SE7EN that has not completed pre-dive test
successfully will enter dive mode if it detects a signicant water
depth. This is a safety feature for emergencies that shall NOT
be misused. Do only start a dive with a powered on rig that has
successfully completed a full pre-dive test prior to your dive.
DANGER:
The battery has a built in realtime clock that provides time and
date to the SE7EN E-module.
Replacing the battery in a E-module with a battery that has a clock
time that differs signicantly from the clock time in the replaced
battery may result in loss of the E-module’s decompression
data and lead to incorrect calculation of decompression stops
and remaining no decompression time.
