ONLY USE THE BATTERY PROVIDED WITH THE UNIT TO ENSURE PRODUCT SAFETY. IF 
THE BATTERY SHOULD REQUIRE REPLACEMENT, ONLY USE GE P/N RS-S131-200-BATT. 

 

THE BATTERY AND BATTERY CHARGER HAVE MULTIPLE LEVELS OF SAFETY 
INCORPORATED IN THE DESIGN, BUT THE FOLLOWING CAUTIONS SHOULD ALWAYS 
BE OBSERVED: 

 

Handling 

 

Avoid shorting the battery 

 

Do not immerse in water 

 

Do not disassemble or deform the battery 

 

Do not expose to or dispose of the battery in fire 

 

Avoid excessive physical shock or vibration 

 

If the battery has visual physical damage, do not use 

 

Keep out of reach of children 

 

Never use a battery that appears to have suffered abuse 

Charge and Discharge 

 

Charge with an appropriate charger only   

 

Never use a modified or damaged unit to charge the battery 

 

Use unit only as specified  

Storage 

 

Store in a cool, dry, and well-ventilated area 

Disposal  

 

Dispose of in accordance with local regulations 
 

 

THE OPERATING TEMPERATURE OF THE BATTERY IS -10C TO +55C. OPERATION OF THE 
RSDETECTION UNIT OUTSIDE THE OPERATING TEMPERATURE MAY RESULT IN REDUCED 
PERFORMANCE. 

The lithium-ion battery does not require an external battery charger. The battery is charged when 
external power is applied and the internal temperature of the battery is between 5C and 44C. The 
battery automatically powers the unit when the external power is removed. 
In the absence of external power, the battery should operate the RSDetection for approximately 48 
hours if fully charged. Refer to the datasheet for specification.
