    Voltage test only go so far , batteries need to be load test to ensure a good battery .

    Finally I found a video that tell us to how much lower the voltage will fall at the time it is started. My battery drops down to 4 volts when I try to start it up. But shows 12.5 volts prior. Now i know for sure my battery is bad. Thank you sir for your video!

    What does it mean if it goes above 14 V the first time I start the engine, and then when I restart the engine, I get a voltage that starts at 12 V, and it gets lower to 10.9 V very quickly, eventually dying on me? Same result before and after I cleaned the alternator with a 4 hour degreaser bath and brush to get all the oil out of it. I checked all the connections as well as cleaning all the connections with Electronic cleaner spray. If I wait about 15 hours, the voltage again starts at 14 V, but when I stop the engine and restart , I again get the battery dash light again and it does the same thing all over again.

    On top of testing with your bolt meter your battery needs to be load tested, that's the truth, that's the only way to tell if your battery is actually good or if it's insufficient

    My car wouldn't start for a while but then I got a jump and it started. Then the next day it wouldn't start. So I unplugged the battery clamps for about a week. Then I connected the clamps back on and my car almost started but couldn't turn over. So my question is, would that be a bad battery or a bad alternator? Thanks!

    The Voltage looks good but the Battery may be having dead cells which will affect cranking.You need need to do an Amperage test with the Meter inline with the Battery and the Load.

  • @mrcabobill1

    First you should be putting the probes on the lead also the battery needs to be fully charged and load test half of the CCA so if you have a 500 cca battery you need to pull 250 amp draw and you need lead adapters for a side terminal battery so you get lead to lead contact .

    I guess my battery is dead I can charge it to 12.56 volts with car running for 20 minutes but looses 1/2 a volt with the head lights on for a minute funny how its got enough power to start engine next day at 12 volts though - common sense prevails EG the battery is 6 years old , slightly bulged out one end and the green indicator is non existant so $273 AUD for caa 620 replacement it is.
