 Battery Cautions
a Warning
To avoid personal injury and/or property damage, adhere 
to the following:
• Replace the batteries immediately when the detector emits 
a low battery alarm.
• Use only batteries that are recommended by BW 
Technologies by Honeywell. Refer to Specifications
.
• Ensure the alkaline batteries are properly installed in the 
detector battery pack.
• Charge batteries using only a recommended BW charger. 
Do not use any other charger. Failure to adhere to this 
caution 
can cause fire and/or explosion.
• The detector must be deactivated to charge the battery.
• Do not calibrate the detector during or immediately after 
charging.
• Both the rechargeable lithium battery pack and the alkaline 
battery pack are user-changeable in hazardous locations, 
but the alkaline battery cells inside the pack can only be 
replaced in a safe area that is free of hazardous gas.
• Warning: The battery pack (M5-BAT08) that is equipped with 
a lithium polymer cell may present a risk of fire or chemical 
burn hazard if misused. Do not recharge, disassemble, heat 
above 212ºF (100ºC), or incinerate.
• Warning: Do not use any other lithium batteries with the 
Micro5/PID/IR detectors. Use of any other cell can cause fire 
and/or explosion. To order a replacement lithium battery 
pack (M5-BAT08), refer to Replacement Parts and 
Accessories.
• Warning: Lithium Polymer cells exposed to heat at 266ºF 
(130ºC) for 10 minutes can cause fire and/or explosion.
• Dispose of used lithium cells immediately. Do not 
disassemble and do not dispose of in fire. Do not mix with 
the solid waste stream. Spent batteries must be disposed of 
by a qualified recycler or hazardous materials handler.
• Keep lithium cells away from children.
