How can you tell if a 6V battery is good?
Place the sensor on the end of the black wire on the negative battery terminal. Look at the digital or meter display on the multimeter or voltmeter. It should read 6 volts if the battery is in good condition and is at least 20 percent charged. If it reads less than 5 volts, recharge the battery.
What happens when battery level is above 95%?
If you experience the problem which is The battery doesn’t be charged when power level is above 95% with AC adapter connected. This is a normal condition for battery protection, not a problem for either the battery itself or the charging function. When the battery is charged to 100%, it will stop being charged.
