i have several old rechargable batteries from corless drills, the drill is broken but the batteries are in perfect order. to assist in my hobbies if I can use these batteries then it woudl save me some $$$$$ on buying separate batteries.
what is the easiest way for me to reduce the voltage from the 18 volts down to either the 12 volts, 9volts or any other voltage.
i know i can buy a 12 volt converter to get to lower voltage, but what about when starting at 18volts. plus i have lots of old 12 volt converters/chargers will these work for anything.
also, i suspect the amperage rating of the device will be an issue, which i do not totally understand, but if my research on the other forums serves me correctly, then as long as the output amperage is greater than the device requirement, then i should be ok, and as long as i have an in line fuse with an amperage rating roughly equal to but greater than the device requirement, say a 1 amp draw device i use a 1.5 amp fuse, it should be fine and i should not have to regulate the amperge. however if this is not correct, how would i regulate the amperage.
thanks.
i can see that this may not be totally clear, but after you comment or question me on anything for clarity, we should be in better shape.
thanks
