Submersible Battery Pack
The OCEAN SEVEN submersible 150-bar and 700-bar rechargeable battery packs are housed in a plastic and a titanium grade 5 container respetively and are composed of 12 NiMH 1.2VDC cells, assembled in series, to create a unique 14.4VDC 4.5Ah battery pack. The battery pack comes complete with a plastic flange (to join the battery pack to the OCEAN SEVEN 3xx probes), with an international battery charger and with the submersible cable needed to connect the battery pack to the Ocean Seven 3xx probes.

Connecting the battery pack, the charger immediately checks the nominal voltage thus automatically selecting the most appropriate action to carry out as:
- If the battery voltage is lower than 1.2 V x cell, the charger carries out the standard charging procedure which implies the recharging at a moderate current for 30m. Whenever the battery reaches the nominal voltage, the charger automatically starts the quick-charging procedure.
- If the battery voltage is higher than 1.2 V x cell, the charger carries out the quick-charging procedure.
- If the battery voltage is lower than 0.2 V x cell, the charger carries out the standard charging procedure thus inhibiting the quick-charging procedure.
Note:
At the end of the quick-charging procedure, the charger undertakes a low-current equilibration charging procedure which lasts 30 m. This procedure is also called trickly-charging procedure. The aim of this procedure is to keep the battery cells in good conditions thus compensating for the auto-discharge.
Led Indicators:
– Green ON: Charger powered.
– Yellow BLINKS: Standard charging procedure/equilibration procedure.
– Yellow ON: Quick charging procedure.
– Yellow OFF: batteries are fully charged.
– Red ON: Bad battery – Immediately stop the charging procedure and disconnect the battery.
