The detector comes with the battery already installed. 
Low battery detection 
The detector has a low battery detection system. Low battery 
detection operates where the PIR has enough reserve energy to 
typically operate for 1 month before complete exhaustion. A low 
battery signal will be sent to the control panel along with regular 
signal transmissions for the control panel to display the status 
accordingly. 
Replacing the battery 
1. Put the control panel in configuration mode to avoid triggering 
the tamper alarm (tamper alarm is not active in this mode).
2. Remove the screw at the bottom of the detector and separate
both parts.
3. Remove the battery.
4. Press the tamper switch twice to fully discharge before inserting
new batteries.
5. Insert a new battery (always use the correct battery type: see
Technical specifications). Make sure the polarity is correct.
6. Close the detector using the screw.
7. On the control panel, exit configuration mode.
WARNING 
 Do not puncture or throw batteries in fire as they might 
explode.
 Keep batteries away from children.
