2.3.2. ProLogger Dimensions
2.3.3. Rechargeable Battery
The ProLogger is fitted with a rechargeable battery with the following characteristics:
Battery:
Internal, Rechargeable Lithium Ion Battery Pack
Capacity
6.8 Ah
Charging:
1.5A Charger that is supplied
0.5A Laptop USB port
Note that there is still current drawn when the rapidPro is switched off or in Sleep Mode and that the current
drawn is considerably less when sub surface recording data but the GPS and Bluetooth are off. The GPS and
Bluetooth are disabled as the pressure reading passes the trigger depth in Rapid Mode.
The instrument draws power continuously whilst running. Battery life is calculated as though the Bluetooth, GPS
and sensor modules are always powered on and based on the following scenario:
a profile to 200m with a decent rate of 5 ms
-1
a recovery rate of 1 ms
-1
5 minutes spent on the surface before a new profile is initiated
rapidPro SVT: 18 hrs operation
rapidPro CTD: 15 hrs operation
rapidPro CTDplus: 12 hrs operation
All battery calculation figures are estimated, and may vary according to deployment temperature and the
inherent battery variability. Valeport accepts no liability for the failure of a battery to last for the expected
lifetime
2.3.3.1. Charging
The battery pack is supplied with a dedicated USB charging and data download interface cable, this must be
used.
In order to gain access to the charging socket the ProLogger module must be removed from the rapidPro profiler.
The comms end cap has a large thread and is sealed by an O ring within the the Peek cover. In case of pressure
build up in the housing the pressure seal is broken long before the thread releases the Peek cover allowing any
gases under pressure to be released safely. The thread must be kept clean and clear.
If the rapidPro is used in a manner not specified by Valeport the protection provided by the equipment might
be impaired.
