    Is your car battery dead? Need a new car battery? Learn how to test if your car battery is bad and how to recharge a dead car battery. Also learn which car battery is best for your car. In this video I show you how to test your car battery with a multimeter, clean corrosion from the battery terminals, test your alternator, test for a parasitic draw, load test a battery, and replace a car battery properly. I also show the inside of a car battery with a bad cell and I show how batteries work with multiple grids and how they go bad with heat, vibration and corrosion. And finally I show you the main difference between the different grades of battery and which is right for you.

Someone said that with all the computers in the newer cars that you should always carefully disconnect the positive first so you don't have 12v going into a computer without having a ground for it to go to. I take it that's not true??

It's more important to know know to test and charge a good battery. A bad one won't hold a charge, a good one can become discharged and then recharged, a truly dead battery won't take a charge. A chronically undercharged battery can be still good but discharged so deep that a "smart" charger can't recharge it automatically at a higher setting in 6-8 hours. If that seems to be the case and your charger hasw a low current setting, try using it overnight, then selceet a higher current.

One way of checking where the problem lies with regards to low charging voltage while car is charging. Clip only told that the positive cable from alternator to the battery could be bad. But it can be the negative "cable" as well. 1. Measuring low voltage with both probes on the battery. Red probe on + and black probe on -. 2. Move only the black probe from the battery to the alternators metal while still keeping the red one on the battery. If it gets good voltage you know there is a problem between metal on alternator and the negative battery pole. Move the black probe from the alternator to some good metal on the engine. If it is still good then you know the bad connection is between engine and negative battery pole. If it is the same low voltage go to next step. 3. Move the black probe back to the metal on the alternator. Now instead move the red probe from the battery to the plus terminal on the generator (shown at 17:55). If it is good then the trouble is between the plus terminal on the generator and the plus pole on the battery. The last step is shown in the clip. I just thought it missed the step 2 checking the negative connection.

16:32 you should have used the red/pink selection (10 MegOhm Input) on the multimeter when just measuring voltage. The selection you use probably activates a load inside the multimeter so basically you are heating up the multimeter and taking power from the charger. It is not so much but right should be right.

Vor Tag

You can call it a multimeter. But the multimeter you show has a battery tester function that most of the multimeters do not have. The battery tester function input has a much lower input impedance so it loads the battery while testing. Though this little measuring device only loads that big battery only a little. It is probably intended for smaller batteries. Basically one could do the same with a regular multimeter. Just measure battery voltage with some load turned on like the lights for example but still have the engine off so it is not charging.

great videos and content ChrisFix! been enjoying and sharing your content for a while. that said you missed to comment about some of the newer more complex charging systems that require using a factory or high level scan tool to preform a 'battery reset'. basically you need to let the car know its got a brand new battery so that it can restart its very complex charging system. charging systems that now take into account more than we can imagine.

shoot also what was shown in the video that you referred to as a load test is not a load test. load test literally pull hundreds of amps as if the vehicle was being started. therefore have much larger gauge wires. what is shown in your video is whats common today, a conductance test. not as good as a true load test. but harder to screw up.

Simpler method to preserve computer/alarm/radio memory is to use an OBD Memory Saver. Inexpensive device that uses 9 volt battery and plugs either into OBD port or 12 volt power supply socket (think old cigarette light looking plug) to keep electricity to these areas when battery disconnected. Use mine all the time. About $12. Google OBD memory saver. Nice video Chris.

I noticed you took the positive terminal off the battery first ... which is against every other video on YouTube ... they all say removed the negative terminal first. Why does the negative terminal come off before the positive terminal? Seems like if you take off the positive terminal first, voltage is no longer applied to any part of the car, there is simply a bare positive terminal hanging in the air. Then nothing that happens on the car as long as you do not touch the positive terminal will matter. Then virtually anything that happens when taking off the negative terminal doesn't matter. You can even put that little red plastic cap from the new battery onto the old battery while you are removing it so nothing can contact it? I am going to change a battery now and do it the suggested way, but I am wondering why? I wanted to check on the Internet what is the correct way to change the battery, but I wonder why? Any wisdom on this would be appreciated. Does it really make that much difference?

Strange place for the battery: Alfa Romeo GTV (916) for weight distribution, in the front of the trunk behind of some upholstery ( hold in place with the plastic plugs that always break) over the fuel tank, under a non removable panel with very little room to spare and very little room for access, and where you can't see what you're doing it's a nightmare really... but the car has a 50-50 weight distribution, and as centered as possible, so slightly better handling, it's difficult to explain how uncomfortable that place is without seeing it, go look it up and have pity in me ps: really cool affordable car that Americans don't know

You CAN use a Multimeter to conduct a load test. Set the multimeter to Volts DC, connect to the battery terminals and crank the engine. If the initial reading is a fully charged battery (12.6V) but under cranking the voltage drops below 10V then the battery is lacking in CCA’s and should be replaced.

In my 2002 Volvo V70 my Battery was in the Trunk and to get to the battery you have to Lift up the Floor And remove the spare wheel Cover then you will see the Spare wheel and the battery was on the Left next to the Spare tyre and to remove the battery cover I had to losen a 13 MM bolt and 2 13 mm Nuts then I had to remove the Bracket then I removed the battery cover then I losened the Negative Battery Terminal then the Positive terminal then I had to remove the 12 mm bolt for the Battery hold down then I was able to remove the Battery I removed it because I was installing Reverse Sensors and I had to remove the Spare tyre because I was removing the rear bumper but you don't need to remove the Spare tyre to replace the battery and my 2002 Volvo is Right hand drive because I live in the Uk and I've owned that car since August 2012 And the thing I like about this car is no one really thinks about buying one but there good Cars Have you ever Driven one of these cars before if you have Driven one they don't have a Good Turning Circle but that's the only design Fault Take care From Joe Sib Cars
