Systems:  ADDM1507(R);  ADDM1510(R);  ADDM2014(R);  ADDM2310(R);  ADDM2517(R); 
ADDM3014(R); ADDM3817(R); ADDL3021(R) may be used in load constantly at temperatures 
below zero to avoid the battery internal temperature to drop below 0ºC for Charging and -11ºC 
for  discharging.  These  battery  packs  are  only  allowed  to  operate  within  these  limits  for  its 
internal temperature. It is of extreme importance to charge the system to 100% if the system is 
not going to be operated for more than 60h.  
For low ambient temperature performance, please cover the Battery side air inlets with the 
special covers provided. 
If, during operation, a problem occurs with the unit, before contacting the AddVolt customer 
support, please have the following unit data available: 
•  Serial number;
