INTERNAL BATTERIES

The OCEAN SEVEN 304Plus CTD housing has in its upper part enough space to accommodate an
internal battery pack. The OS304Plus is powered by a single 3.6V battery; different types of battery can
be installed in the CTD housing.
 2 x size "AA" Alkaline 1.5V battery assembled in single battery pack
 1 x size "AA" Lithium non rechargeable battery
 1 x size "C"
 1 x size "D" Lithium non rechargeable battery
 NiMh rechargeable IDRONAUT custom battery pack (3x1.2 AA)
When the CTD is not used for long periods (e.g. 2 weeks or more), we suggest disconnecting the
internal battery pack connector from the CTD electronics or removing the internal battery pack from
the CTD to prevent the internal batteries from damaging the CTD due to battery acid leakage. This is
why the OCEAN SEVEN 304Plus CTD is shipped without batteries installed.
INSTALLING TWO 3.6V LITHIUM BATTERIES IN THE DOUBLE BATTERY HOLDER AND
CONNECTING IT TO THE OS304Plus TOP COVER WILL CAUSE A PERMANENT DAMAGE
OF THE OS304Plus CTD ELECTRONICS.
Optional USB Laboratory cable
The status of the internal battery pack can be derived from the battery diagnostic reading of the CTD
start-up message. This last is carried out only when the USB laboratory cable is not connected.
Therefore, to update the battery status after the recharging, switch on the CTD without the USB
laboratory cable connected.
