CIRAS-3 Operation Manual V. 1.09  45  support@ppsystems.com 
 
Battery Pack 
For field use the system is powered by internal, rechargeable battery packs.  Up until June 2017 the 
CIRAS-3 was powered by a single, internal rechargeable 7.2V Li-ion battery pack (Aved) providing 
system operation up to 8 hours.  Starting in July 2017 we began supplying instruments with two 7.2V (8.7 
Ah, 63 Wh) Li-ion battery packs (Inspired Energy) improving system operation for up to 12 hours (actual 
operation time will vary depending on environmental control settings).

ALWAYS MAKE SURE THE BATTERY PACKS ARE FULLY CHARGED THE NIGHT BEFORE USE. 
Please note that batteries are shipped only partially charged due to shipping regulations.  We highly 
recommend that you charge them to full capacity upon receipt to avoid any potential damage or loss of 
battery life. 
 
TIP 
To reduce the weight of the CIRAS-3 console 
approximately 0.2 kg you can remove one of the 
battery packs providing up to 6 hours of 
continuous use (depending on settings and 
controls) in the field.  We recommend 2 battery 
packs for normal use but if one battery pack is 
used it must be placed in the lower battery 
compartment which is the one that is flush with the 
inside battery compartment door as shown here.
