  • This tutorial explores how to test your car battery, but you may be wondering, is there a difference between testing a car, motorcycle, boat, or RV batteries? The answer is yes, the principle is the same, but the voltage requirements are different. Each of these uses a different type of battery and has different requirements for starting and running the vehicle. Also, there is a difference between a deep cycle battery and a starting battery. Some RVs have both a starting battery and a deep cycle battery for running the electronics. The procedure for testing this type of battery is different from testing a car battery. - Source: Internet
  • When you do this test, you need to watch the meter closely because the numbers will drop very quickly, and then, the alternator will kick in, and the numbers will go up over 14 if everything is working well. This is not the number you are looking for, and you will need to try to see the lowest number as the car starts. If you miss it, you can do the test again, provided that your battery has enough charge left. Before starting over, you should let the car charge on the alternator for about 5 minutes and then begin by leaving your car lights on with the engine off again before retesting for CCA. - Source: Internet
  • If the battery is not reading the proper voltage with the multimeter, the first thing you should check is whether there is corrosion on the posts. If there is, you can disconnect the battery cable ends and terminals with sandpaper or a wire brush. Reconnect the battery cables, always starting with the positive cable first and retesting the battery, starting with step 3 on this list. Please make sure the cables are tight enough and can’t be pulled off of the posts easily by hand. - Source: Internet
  • The black cable procedure is different: it belongs to the negative pole of the battery that supplies the current. Connect the other side to an unpainted metal part on the engine block of the breakdown vehicle, not to the empty battery ’s negative pole. Once the cables are correctly attached, you can start the helper car. - Source: Internet - Source: Internet
