Introduction

The supplied USB charger is capable of charging the battery with a 1.5 A current.
The battery pack has intelligent charging and discharge circuitry. There is no 'memory' to the pack so partial
charging sessions will not reduce the capacity or life of the pack. The capacity of the pack will, however, reduce
with age.
It is advised that the ProLogger battery is never allowed to become fully discharged. In a fully discharged state
the battery is open circuit. In order to reduce the chances of battery becoming fully discharged the ProLogger will
disable all sensors with 1 hour's operational charge left. From disabling the sensors you have approximately 50
hours to start a charging session to prevent the battery becoming open circuit.
If the battery is completely discharged and, therefore, open circuit it will take 50 minutes, using the supplied 1.5A
charger, to start taking on a charge. Please note, during this 50 minute period of charging none of the LEDs will
be lit.
It will take approximately 12 hours, using the supplied 1.5A charger, to fully charge the battery from a near flat but
not open circuit state.
When the charging session is complete, disconnect the charging cable from the ProLogger before disconnecting
power from the charger.
When replacing a charged ProLogger into a rapidPro with the Mag Key inserted, simply pull the Mag Key out to
initialise the instrument. If the Mag Key is not in the instrument when the ProLogger is replaced it is necessary to
insert the Mag Key and then remove it to initialise the profiler.
2.3.3.2. Battery Life Expectancy
The batteries installed in the ProLogger will loose capacity over time. Lithium-ion batteries use the movement of
ion particles to create and store an electrical charge. Eventually these ion particles are trapped and can no
longer move around. The batteries then lose their capacity to store energy.
Under normal operational conditions the rapidPro battery pack should offer a practical, usable capacity for a
period in excess of 4 years.
2.3.3.3. Shipping Your ProLogger with Lithium Ion Batteries
The Lithium Ion battery within this product, when packed and shipped in its transit box, conforms to UN3481,
PI967 section II and its additional requirements.
No battery handling labels are required.
