Smartcharger 500W And 750W
A simple charger works by supplying a constant DC source to a battery being charged. The simple charger does not alter its output based on time or battery charge. This simplicity means that simple chargers are very cheap, although there is a trade-off in quality. A trickle charger is typically a low current battery charger, used to charge small capacity batteries.

* 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. |
