Battery Testing and Internal Resistance

The video tutorial explains battery testing methods, highlighting the limitations of using a voltmeter and the advantages of using the BT 200 battery tester from Top Don. It demonstrates testing both good and bad batteries, showing how the BT 200 provides accurate results by considering battery type, size, and internal resistance. The tutorial also covers testing the alternator charging system. The BT 200 is recommended for its precision and reliability, making it a superior choice over traditional methods.

What is a limitation of using a voltmeter for battery testing?

• It provides too much information.

• It requires special training.

• It does not account for battery type or size.

• It is too expensive.

What is one advantage of the BT 200 battery tester over traditional methods?

• It is cheaper than a voltmeter.

• It can test multiple batteries at once.

• It does not require any power source.

• It provides more accurate and targeted results.

What should you do before testing a battery with the BT 200?

• Clean the battery terminals.

• Remove the battery from the car.

• Find the battery details.

• Charge the battery fully.
