TESTING MY BATERRY CHARGER METHOD 2

-
  1. 1
    Turn on your vehicle’s battery. Once the battery is on, switch on the headlights to “load” the battery and reduce any surface charge that the battery may have built up. However, don’t start the engine just yet. Before you test how well the battery is charging, you’ll take what’s known as a “static” reading to confirm the battery’s current level of charge.[10]
    • If you like, you can also turn on your vehicle’s radio, fan, emergency flashers, and other electrical components to load the battery even more.[11]
    • Eliminating surface charge helps to ensure a reading that accurately reflects the alternator’s charging capabilities.

    Set your multimeter to “DC." Turn the dial that controls your multimeter’s test mode so that it’s primed to measure DC current in the next-highest voltage range to your vehicle's battery. Like small appliance batteries, car batteries rely on direct current electricity to power the motor, headlights, fans, and other electrical components.[12]
    • Car batteries typically put out 12 volts of electricity, which is about 6 times more than most personal use batteries. To avoid overloading your multimeter, make sure you have it set to a voltage higher than that of your battery (20 DCV on most tools).[13]

    Connect the multimeter test probes to your vehicle's battery terminals. The best way to do this is to insert the tips of the probes vertically into the spaces between the terminals themselves and the surrounding metal fittings. That way, you can ensure that they don’t accidentally slip out at any point during your test. Position the negative probe first, followed by the positive probe.[14]
    • Immediately after attaching both probes, your multimeter should display a reading somewhere in the range of 12.6 volts. This is the battery’s static voltage, which only shows that it’s holding a charge, not that it’s charging the way it’s supposed to.[15]
    Tip: Installing alligator clips on the ends of the test probes could come in handy if you’re having trouble keeping them on the terminals.[16]

    Start your vehicle’s engine. The number displayed on the multimeter will drop suddenly as the starter pulls power from the battery to begin turning the over the engine. Allow the engine to continue running for about 5 minutes to give the alternator a chance to charge the battery a small amount.[17]
    • If your headlights or other electrical components dim or cut out momentarily when you start up the engine, it could be a sign that your battery is going bad.

    Shut off the vehicle completely and look for a reading of 13.2 or higher. Turn the key in the ignition to turn off everything at once, including the lights, radio, and other electrical components. As you do, the multimeter should display a new reading. If this reading is higher than the battery’s static voltage, it means that the alternator is doing its job and charging the battery correctly.[18]
    • If there’s no change in the reading, a failing alternator could be to blame. Consider making an appointment to have your vehicle looked at by a professional.[19]
    • Look for a reading within the same range if you’re testing an external battery charger.

How to Make Your iPhone Ring Louder By  Chris Phone Hospita The iPhone has several ring settings. For example, you can change the ringtones, set the ringtone to "Vibrate" or adjust the volume of a ringtone. If you can't hear the ringtone when someone calls your iPhone, you can make the phone ring louder by increasing the ring volume. It takes little time to make the iPhone ring louder to avoid missing future calls. Step Press the "Home" button, and unlock your iPhone.

Hackers Can't Break This Wi-Fi Security Steps If you can’t avoid public Wi-Fi networks, you should at least ensure you’re well-protected when using them. Fortunately, there are some useful tips that you can follow to yourself safe on public Wi-Fi networks: 1. Verify the Network; Configure and Turn off Sharing Remember that hackers are very clever, so its better to surf and play smart. Read the network name very carefully and ask an employee of the business if the link is legitimate. You can also ask the offering IP address. As mentioned above, hackers often set up fake networks, so verify the name to avoid being victim. Another important thing to consider, when connected to the public internet, do you really need to have sharing preferences turned on? Obviously, not! So right after you verify the network, turn off the file sharing option. File sharing is usually pretty easy to turn off from the system preferences or control panel, depending on your operating system. 2.
