What Should A Fully Charged 6 Volt Battery Read. Any voltage above 129 volts is a good indicator that your battery has excessive voltage. If the reading is 1245 volts or less the battery is low and needs to be recharged.
It should read 6 volts if the battery is in good condition and is at least 20 percent charged. When a battery reads only 12 volts under the above conditions its almost fully. Regularly check battery state of charge.
You can do this without disconnecting the batteries from each other as long as you test across one batterys posts.
Place the sensor on the end of the red wire onto the positive battery terminal. Look at the digital or meter display on the multimeter or voltmeter. This is 146147 volts for a 12 volt nominal installation and 292294 volts in a 24 volt site. At 50 the reading will be 203 VPC Volts Per Cell and at 0 will be 175 VPC or less.
