3.1.4.  Discharge -20ºC to +60ºC 

 

Discharge Temperature Limits:  As shown below, 

≤

 80%RH 

 

The  battery  shall  be  capable  of  continuous  discharge  within 
the Operating Boundary as shown in the graph below. 

 

Host  devices  should  be  designed  for  a  controlled  shutdown 
following  battery  notification  of  termination  by  the  battery 
sending  TERMINATE_DISCHARGE  alarm,  prior  to  protection 
circuit cut-off.
