These  warnings  and  safety  notes  are  particularly  important.  Please  follow  the 
instructions  for  maximum  safety;  otherwise  the  charger  and  the  battery  can  be 
damaged or at worst it can cause a fire.

Never leave the charger unattended when it is connected to its power supply. If any 
malfunction  is  found,  TERMINATE  THE  PROCESS  AT  ONCE  and  refer  to  the 
operation manual.

Keep the charger well  away from dust, damp, rain, heat, direct sunshine and 

Never drop it.

vibration

The allowable input voltage  is 12~18V DC

This charger and the battery should be put on a heat-resistant, noninflammable and 
nonconductive  surface.  Never  place  them  on  a  car  seat,  carpet  or  similar.  Keep  all 
the inflammable volatile materials away from operating area.

Make sure you know the specifications of the battery to be charged or discharged to 
ensure it meets the requirements of this charger.  If the program is set up incorrectly, 
the  battery  and  charger  may  be  damaged  .It  can  cause  fire  or  explosion  due  to 
overcharging.  This  warranty  is  not  valid  for  any  damage  or  subsequent  damage 
arising  as  a  result  of  a  misuse  or  failure  to  observe  the  procedures  outlined  in  this 
manual. 

Standard Battery Parameters

Be very careful to choose the correct voltage for different types of battery otherwise you 
may  cause  damage  to  the  batteries.    Incorrect  settings  could  cause  the  cells  to  fire  or 
explode.
