I'm trying to test some 18v batteries. Need to know which holes to put leads into and where to set the knob.

Don't tell me to GTS. I'd rather get human advice.

BTW testing batteries without a load can hide ones in a poor state. Battery testers put a resistor across that draws current. Batteries can develop significant internal resistance (basically a series resistor) which lowers voltage when there's a load, but has little effect when measuring with a high-impedance multimeter like that.

It was suggested to me earlier to test it on her load but to be honest I don't have any idea how to do that because the only way to put it on her load is to snap it into the tool and pull the trigger.
