The batteries used to power these items are lead-acid batteries and are capable of producing a constant 6 volts until they are almost fully discharged (about 80 percent). You can test if your battery is producing 6 volts using a voltmeter or multimeter.et a multimeter or voltmeter to measure volts in the range 0 to 12, if it has variable settings.
