Poseidon CCR Cell Modules
Poseidon restricts access of cells only to certified Poseidon CCR divers or instructors of students undergoing certification. If you order a cell, we will send you a liability release that you must complete and return to us along with documentation of your certification before the cell order will be accepted.
† Although we make every effort to keep all these cell modules in stock, because of relatively low unit sales volumes for some of these models, they can occasionally have a 1-2 week lead time in order for Dive Gear Express to be able to offer the freshest cell available.

How to resurrect a completely dead Poseidon battery
If you store your Poseidon e-module smart battery for an extended period of time, the battery will self-discharge until it is completely dead. In this circumstance the Poseidon proprietary multi-function desk-top intelligent charger will not recognize the battery when it is inserted in the charger and will not begin charging the battery. Ironically, the total absence of any charge in the smart battery makes it impossible to charge the battery. The solution is to force just enough charge in to the battery to allow the desk-top charger to detect the battery and begin a charging cycle.
To bring your battery back to life, there are some things you will need: The dead smart battery and it's desk-top charger, a Se7en (an MK VI won't work) with a CANbus cable and M28 dive computer. I've used other methods in the past, but I prefer the method described. Keep in mind this is not a last minute "quick fix" to re-charge a depleted battery. Although the steps required to get the battery to begin accepting a charge take only a few minutes, it will require several hours to re-charge the battery and then perform a learn cycle.
- Charge the M28 battery until full and also power up the Poseidon multi-function desk-top battery charger.
- Connect a CANbus cable directly between the M28 and Se7en.
- Now insert the completely discharged smart battery in the Se7en .
- Power up the M28 and using the M28 menu navigate to "Dive mode" and select (CC) SE7EN. Using the M28 menu navigate to "Settings >: Connect >: PowerOut" and select "ON", then exit the menu. Make sure the date/time/zone are set correctly in the M28 and if not adjust the values accordingly.
- Using the M28 menu navigate to and select "Start SE7EN". The Se7en may not actually power up and start, but if the Set SE7EN RTC menu item then appears, navigate to and select the Set SE7EN RTC item which should also set the RTC in the battery.
- Wait a minute, then remove the battery from the Se7en and immediately place the battery in the desk-top charger. Within a few seconds the Charge Status LED should begin blinking green, indicating the battery is charging.
- While the battery is charging, disconnect the M28 from the Se7en and shutdown the M28.
- Once the desk-top charger indicates smart battery is fully charged, reconnect the CANbus cable directly between the M28 and Se7en. Power up the M28 and using the M28 menu navigate to "Dive mode" and select (CC) SE7EN. Do this while the battery is removed from the Se7en.
- Power up the Se7en by inserting the battery. The M28 should begin displaying the Se7en POST.
- A completely depleted battery will probably have erased its firmware, if so you will see an error 09 during POST and/or the M28 may indicate a network communications error. Regardless, use the M28 menu navigate to Apps>System>Force fw update and select Force fw for the BAT item.
- Once the battery firmware has been updated, the Se7en POST will time out and shutdown. Remove the battery, reinsert the battery again and once the Se7en begins it's POST, then verify the Se7en battery firmware has been updated by using the M28 menu to navigate to Apps >: System and in the system information find "Connected Units" item BAT with value of current firmware version.
- Set the the Se7en RTC again, shut the Se7en down, remove the battery and perform a learn cycle on the battery with the charger. Once complete your dead battery has been resurrected, but keep in mind that allowing to battery to completely deplete may have shortened it's service life.
From the Poseidon Se7en User Manual: "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 desk-top charger. If this is not possible, then the best long term solution is to the leave the battery on the charger with power to the charger turned on. The method of monthly top-off of charge, however, will maximize the battery life."
