Schumacher SI263 用户手册

While preparing to charge a battery, read and follow these  

guidelines: 
1.   Ensure you’re working with a 12- or 6-volt lead-acid battery. 

To determine the voltage of the battery, refer to the vehicle 

owner’s manual or the battery markings. Set the Battery  

Manager to the 6V or 12V mode accordingly.

2.   Clean the battery terminals. Be careful to keep corrosion from 

getting in or around your eyes.

3.   Wear safety glasses. (See “Personal Safety Precautions” section 

this manual.)  

4.   Read all of the battery manufacturer’s specific precautions, for 

example, removing or not removing vent caps while charging 

and recommended rates of charge.

5.   To add water to batteries with removable vent caps, carefully 

pour distilled water into each cell until battery acid reaches 

the level recommended by the manufacturer. This helps purge 

excessive gases from the cells. Do not overfill. If the battery is 

sealed, with non-removable vent caps, no action is necessary.
