Testing a Battery With a Carbon-Pile Load Tester

- A carbon-pile load tester draws a large amount of current from a car battery so that we can determine if the battery has enough current capacity to maintain a sufficient voltage to start the car.

I like this test cause the gauge tells you right away what's going on ..and the testers are cheap at harbor freight I've had one for 20 yrs still going strong. You can also load the charging system and watch alternator output.
There are many other uses for the carbon pile tester such as starter cable and alternator / cable testing would be cool if you could do examples of those

I normally just go to walmart and load test it in 5 minutes .
But good video for ppl who have one of these .
Vat-28 then Vat-40 used many years.
Hello, so ypu mentioned smoke coming out the battery what about smoke voming out of the tester way before the 15 seconds, even before i get to the desired CCA? I have the exact same one you have 500amp from solar.
Question, why is it on a lot of these carbon pile load testers the buzzer is going off way before the 15 seconds at the end of the test?
I don't know the answer, but as a teacher, I like it. The old VAT-40's didn't beep, and students would leave the load turned on until smoke started coming from the inside of the tester. The load testers last a lot longer when they have a beeper!
Surface charge on the battery plates need to be taken off before the atual load test is preformed. The battery is loaded for 15 sec at half the CCA. Battery is allowed to rest for 15 sec. Load test is reaplied for 15 seconds and the voltage cannnot drop below 9.6 volts. This is what is written in the Bible!
Sir I need your Instagram profile
Haha. No you don't.
