Can a car battery be bad even if it tests good?
Yes, sometimes a battery can still be bad even if it tests good. If a vehicle has a battery that keeps running down, but the battery and charging system both test OK, the problem may be a key-off current drain that’s sapping the battery of its reserve power.
How can you tell if a car battery is bad without a multimeter?
One way to tell if a car battery is bad without a multimeter is by watching the brightness of your headlights. If your headlights dim noticeably as the engine turns over, your battery doesn’t pass the load test. The battery should hold enough charge to handle the 10-15 minutes before the engine starts, and once the engine turns over.
When should you replace a dead battery?
If your battery is 3 years or older, it is likely to need replacing to avoid repeated failure. While you may be able to jump-start it, the catalyst for its initial failure is still threatening the lifespan of your battery.

One of the first signs of a failing battery is a slow, long crank before the engine starts. If you notice a difference in your normal startup of the car, it’s advised to get your battery checked. In most cases, you’ll only need to recharge your battery.
What is the average life of a car battery?
The average life of a car battery is typically around three to four years. Replacing your car battery is part of routine maintenance, and it is recommended to get it checked and inspected after three years, even if it hasn’t needed replacement yet.

No, if the measured reading is less than 12.2 volts, the battery’s resting voltage is weak, which means it most likely needs to be charged or replaced.
Can a battery read fully charged and still be bad?
If batteries have open cells, they may read fully charged at idle but fail under a load test every time. Once a battery reaches this point, it cannot be salvaged.
How can you tell if a battery is bad without a tester?
The most common symptoms of a bad battery include a battery light illuminated on the dashboard, a slow crank when starting, frequent jump starts, clicking noises when turning the engine, dim lights, and the car not starting.
