SPM Flex Gas Detector
Battery operation
The SPM Flex gas detector is supplied with a power adaptor/charger than can 
connect the detector’s power connection and a standard wall outlet� (Verify 
that the correct power adaptor/charger has been ordered for local operation�) 
The power adaptor/charger is designed for indoor, dry-location use only� The 
lithium-ion battery pack provides continuous operation of 6+ hours, depending 
on sampling conditions and detector configuration� The battery’s charge time is 
typically 4 hours� The detector can be operated while its battery is being charged 
(this may increase the charge time)� Because batteries discharge slowly when not 
in use, Honeywell Analytics recommends keeping the detector connected to the 
power adaptor/charger when not in use�
• The battery is not field-replaceable� Return the detector to Honeywell 
Analytics if a battery replacement is necessary�
• Risk of fire and burns� Do not open, crush, heat above 140ºF (60ºC), or 
incinerate the battery� Follow manufacturer’s instructions�
WARNING

How to extend battery life
Power consumption is optimized to extend battery life when not in monitor 
mode� In addition, the detector should not be exposed to extreme temperatures 
which shortens battery life� The time before recharging is required can be 
extended by taking the detector out of monitor mode when it is not in use�
How to recharge an overly-discharged battery
If the battery indicates 0% charge and does not appear to be charging when 
plugged into the power adaptor/charger, it may be overly discharged� Follow 
these steps:
1�  Verify that the latest software has been installed� The detector’s software 
version can be found by navigating to the
 Software 
option on the
 Review 
menu� If necessary, the current software can be downloaded from the SPM 
Flex section of the Honeywell Analytics website (see “Contact Information” 
on page 7)� Install the new software from a USB flash drive by following 
the prompts in the 
Update Program
 option on the 
Maintenance
 menu�
2�  Turn the detector off and then power it up again� This will reinitiate the 
charging circuit� Initially (until the battery reaches the normal charge range), 
the detector will slow charge� The process can take 6 hours�
