I purchased a Black and Decker Battery Charger that charges two different voltages of batteries; it charges both 12V, and 18V batteries.
I checked the output voltage of the charger itself, and it's output is 47 volts continuous.
How does that work, does the battery size become the limiter as to how much voltage it will receive, or does the charger reduce it's output, based on battery capacity, during the charging cycle?
I have another question as well.
I have a 24 volt DC power tool, that had a 500mA charger that doesn't work anymore. Can I use a different charger, that has a much higher amp rating instead, without damaging the power tool?
Thanks,
Gary
