* Note: High voltage versions  SR750B72, 91, 92, 93 have  a manual  boost function.  Initiation of boost charge is by pushing the BOOST switch or relay contact. Termination of boost charge is by manual push button (FLOAT or STANDBY) or by the time set by the internal timer (BT setting).   They do not have a current terminated boost function.
