Certain types of batteries benefit from periodic equalizing charge, which can 

stir  the  electrolyte,  balance  battery  voltage  and  complete  chemical  reaction. 

Equalizing  charge  increases  the  battery  voltage,  higher  than  the  standard 

complement voltage, which gasifies the battery electrolyte.

 

If the battery is being over discharged, the solar controller will automatically 

turn  to  equalize  charging  stage,  and  the  equalize  stage  remain  120mins.

 

Equalize  charge  and  boost  charge  are  not  carried  out  constantly  in  a  full 

charge process to avoid too much gas precipitation or overheating of battery.
