4. After turn on the power, the indication of the voltmeter is the battery voltage, press the limited voltage setting button and turn the limited voltage adjustment button to make the voltmeter indicate the maximum limited voltage needed in charging. A normal 12V lead acid battery set a limit voltage of about 15V or depends, when the charging voltage raise to the voltage limiting, the voltage will not raise and the electric current will decrease automatically; if the voltage could be adjusted to the maximum without voltage limiting, you have to properly control the charging electric current and time to in case over charging damage the battery.

5. Turn the electric current adjustment button slowly to make the voltmeter indicate the charging electric current needed, the charging electric current and time depends,but in general it is appropriate to set it to ten percent of the total electric current of the battery capacity, the complete charging time is about fifteen hours, if the voltage limit setting is correct, when the charging electric current mentioned above decrease to below twenty percent, the charging process could be viewed as completed.
