  • How to test a car battery (Video)

    This is a ~two-minute video showing you how to test a car battery using a car battery tester (voltmeter or volt gauge). The voltmeter has a digital reading and it comes with a universal car cigarette lighter power plug. Make sure you have left your car in the garage more than 12 hours if you want an accurate result.

    Step 1: Locate your car cigarette lighter power socket.

    Step 2: Connect the voltmeter to your cigarette lighter socket.

    Step 3: Turn on the ignition.

    Step 4: The first reading (not yet starts the car engine):

    • 12.60 V means the battery is 100% charged.
    • 12.35 V means the battery is 75% charged.
    • 12.10 V means the battery is 50% charged.
    • 11.95 V means the battery is 25% charged.
    • 11.70 V means the battery is discharged.

    Step 5: Start the car engine. The reading should be in between 13.8 V and 14.4 V.

    Step 6: More than 14.50 V means overcharging. More than 12.60 V means no charge.

    The battery is needed to be replaced if the reading is lower than 11.0 V all the time.

  • Car Battery Tester – Test Your Car Battery

    Car Battery Tester
    In the market today, there are many types of car battery tester available from the cheapest $10 up to few hundred dollars. The reason some battery testers with higher price tag is they have extra capabilities including higher measurement range, bad cell detection, high/low voltage to test both the battery and starter. Some advance tester provide high amp charging function and engine start assistance too. However, as a normal user, we normally just need a battery tester that shows the available voltage power.

    Here we have go a cheap car battery tester (you can called it voltmeter or volt gauge) purchased from Autobacs. It cost $22 dollars and we got it for $7 during a sales promotion. This gauge comes with a digital reading, a protective cover, and a universal car cigarette lighter power plug and lead wire. We recommend using this voltmeter to test your car battery because you don’t have to care about the DC or AC reading and you don’t even need to open up your car hood. It is 100% safe for people who know nothing about cars. Moreover, the digital reading is more accurate and easy-to-read. (more…)
