Can a battery be bad with good voltage?
Check the reading. A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.
Why did my battery die but then charged?
Shortly thereafter my gauges started to act up and the battery dies again. Turned out it was not the battery all along but the chassis ground right up front next to the battery. Once I cleaned the threads and reassembled all my battery and gauge problems were solved.
Can you recharge a completely dead sealed lead acid battery?
Can I recharge a completely dead sealed lead acid battery? Sealed Lead Acid batteries fall under the category of rechargeable batteries and if they are ignored, not charged after use, not charged properly or have reached the end of their intended life span, they are done. If it’s completely dead, it’s gone and you need to find a replacement.
What does it mean when a car battery is not charged?
The battery is shot. The charger indicating a fully charged battery means one of two things: the battery is fully charged, or the battery is faulty and won’t take a charge. A battery that has sat for a month and then expended some energy trying to start the engine is not going to be fully charged.

What is the voltage of a fully charged car battery?
Inside of both of those batteries are six cells that produce voltage and current. Each cell when fully charged produces 2.12 volts. Doing the math 6*2.12 gives a voltage of 12.72 Volts for a fully charged battery. industry standard is anything above 12.6 is considered fully charged. As the battery discharges, the voltage drops.
When does a car battery lose its power?
3. Disuse If you’ve let your car sit idle for awhile without using it, usually at least two weeks or more, then your battery might have lost enough power that it can no longer start your engine.
