What Voltage Is A 9 Volt Battery Dead. He measured the voltage of one of the spent cells at 301V and was wondering if that could be considered dead. Are any of th.
Answer 1 of 5. After replacing several 9-volt batteries with brand new ones Im left with a bunch of old batteries in various states of charge and condition. Two 6 volt batteries wired in series to produce 12 volts are also commonly used in recreational vehicles as they last longer than one 12-volt battery.
You need a resistor and alligator clips.
The nine-volt battery format is commonly available in. A suitable voltage for an AA and Triple-A batteries is something in between 11V and 15V. If the battery is old or has bad resistance it could still be bad and show a high voltage reading of 7 to 9 volts. A regular AA battery which is a an alkaline battery has a 15 nominal voltage charge but when it is fresh or brand new it will have 165 volts.
