We recommend that the battery is charged every night when the system is in regular use and ALWAYS 
charge the internal battery(s) to full capacity prior to storing the system for extended periods.  We also 
highly recommend that the internal battery(s) gets charged every 3-4 months when not in use to preserve 
capacity.  A power supply is included with the CIRAS-3 for charging the internal battery(s) or for extended 
operation.  To charge the internal battery(s), connect the power supply to the “EXT PWR” plug on the 
back of the CIRAS-3 main console.  The indicating LED above the plug shows the charge status of the 
internal battery.  It will illuminate a steady green when charging and when the battery is fully charged.  
The battery capacity can be observed in the lower right hand corner of the display when the system is up 
and running with the measurement or graphical display on the LCD. 
If you need to order a replacement battery pack please make sure that you are ordering the correct type 
as highlighted earlier. 
Battery Removal 
If a battery needs to be removed or replaced, simply open the front battery cover and allow the door to 
gently drop down.  Grasp the black tab on the battery and pull it out of the compartment.  See 
Battery 
Pack Installation on page 46 for information on installation of battery packs. 
Battery Storage 
Li-ion batteries do not have a “memory” so there is no need to fully discharge them after use.  If the 
instrument is not going to be used for weeks or months then we recommend that the internal battery 
packs have at least 25-50% charge capacity before storing away. 
Battery Disposal 
Proper and safe disposal of Lithium-ion batteries is critical as improper disposal 
may cause damage to human health or the environment.  Please check your local 
area for Lithium-Ion battery recycling locations to learn how you can safely dispose 
of the batteries.  Material Safety Data Sheets (MSDS) are available from the battery 
manufacturer if required.  Please contact PP Systems for more information.
