Diagnosing a Car Battery Problem.

Your car’s battery is the brain of the electrical system. What I’m implying is…Without it nothing will work. Just like a battery in any electronic piece of equipment, your car’s battery will need to be changed every 3 to five years on average. Some auto batteries require periodic service and need to be serviced on a recurring basis to get optimum performance, although some are referred to as [maintenance-free], meaning that they do not need any check.

There are a number of automotive tribulations that will occur with signs or symptoms that look similar a dead battery but, with the suitable methods plus expertise, these can easily be recognized before you go out and purchase a new battery pointlessly. For your connivance there is battery tenders available that will retain your battery in highest condition.

Things You will Need…

>>>Battery testing meter.

>>>Battery load tester.

>>>Open end Wrench(s).


>>>Battery terminal cleaning solution.

>>>Battery terminal cleaner [some 100 grit sandpaper works to].


Using a Digital Multimeter to analysis the batteries voltage level. A battery in perfect effective order should read 12.66 volts DC between the positive [+] [RED] and negative [-] [BLACK] terminals. This number possibly will be a little higher or lower depending upon its size and producer, but should not be less than twelve volts, as well as no more than thirteen volts. When a battery has totally charged and reads a voltage fewer than 12V at rest, you may have to verify the battery’s water level and top it up if needed. If the water height in the battery is Good, it may well need to be replaced.

Now inspect the battery terminals for signs of oxidization along with lose connections. It’s very common for deterioration to develop on the battery terminals. In frequent cases it’s fully evident, although it is even probable for rust to be obscured between the terminal and the connector. This may lead to not enough charging, the same a loss of power to the vehicle. Detach both terminals and cleanse them with a battery terminal cleaning mix and a wire brush or [100 grit sandpaper]. Reconnect the battery terminals and tighten them.

The next step is to look that ground cable is correctly grounded. Follow the negative [-] [BLACK] wire from the battery terminal to where it grounds to the frame of the auto. Use the multi measure to test the resistance between both ends of the cable. A good ground cable will show 0 ohms, or awfully near to it. Any reading more than 1 ohm suggests a flawed ground link. Repeat this all over again between the negative terminal and the vehicle’s body ground.

Battery load tester.

Now we’re going to carry out a load test. Place the Battery Load Tester between the positive [+] [RED] and negative [-] [BLACK] terminals. While this load investigation is being done, this gauge will present the battery’s working under a definite load. If the battery has been adequately charged and fails the load test, replacement of the battery is necessary.

Testing the alternator to determine if its sending ample power to the battery. With the multimeter to test the battery’s voltage [as per above] with the vehicle turned off. Now start the car and assess the voltage reading ever again. At the same time as the auto is running, the voltage ought to be near to 14.4 VDC. If the voltage is reading the consistent if the automobile is running as it is after it’s turned off, or if the voltage drops while the auto is running, the alternator could not be operational acceptably and could need to be replaced. When the alternator is not properly keeping the battery charged, the symptoms may be very alike to those that happen by means of a vanishing battery.

Some Methods & Warnings To Be Aware Of!

>>> Filthy or else poorly fixed battery terminals is the as a rule recurrent basis for battery related van troubles. Always wipe [try some baking soda & boiling water mixture]and tighten the battery terminals rather than going out and buying a new battery…Always dispose of exhausted batteries correctly.

>>> Make sure you clean your fingers once handling a battery. [Or better yet wear gloves]. Car batteries may well be full of sulfuric acid, in addition to the terminals are typically constructed? of lead. Do not smoke at the same time as servicing a battery. Hydrogen gas could be released from particular types of vehicle batteries, and an explosion could happen.

>>> Its at all times a good plan to keep your van and it’s battery properly maintained. There are Battery Tenders available to make sure your battery is in top state as well as will be all set to start your vehicle when you need it. If you do decide on a new battery buy in a cheap Battery Tender as well. This will make sure years of lengthy life from your battery.
