Test / Diagnostyka / Sprawdzenie Akumulatora samochodowego

Below are the values ​​that a healthy battery should be within: Battery voltage with the engine off: 12.0V - 12.5V If the value drops below 10.2V, it is recommended to replace it. The battery voltage should not drop below 10.0V during cranking. If it drops to around 9.0V, the battery is not suitable for use. With the engine running and a load (lights, radio, air conditioning, etc.), the voltage should be between 14.0V - 14.4V. If it drops significantly to around 12.5V - 13.5V, it indicates a problem with the alternator, which is not providing enough power to charge. The current draw test with the engine off and the car locked should be within 0.05A. My car doesn't have an alarm, hence the low current draw.
