    The most common problems with laptop batteries</h2> </h2>

    Hi, there! You, probably, have a laptop. It’s not a big deal to have a laptop today. We use it everywhere: at work, home, when we chat with friends or watch a movie. But sooner or later you will face a problem: </p>

    Type of battery</strong></td> Pros</strong></td> Cons</strong></td> </tr>
    Lithium-ion</span></p>

    Performs due to the lithium ions movement from the negative electrode to the positive electrode</td> </p></span></td>
    • Lightweight</li> </li>
    • High performance characteristics</li> </li>
    • Without “memory effect”</li> </li>
    • More environmentally friendly than the other types</li> </ul> </td>
    • High price</li> </li>
    • Sensitive to high temperature</li> </li>
    • Aging effect</li> </ul> </td> </tr>
    Nickel-cadmium (NiCad)</span></p>

    Uses nickel oxide hydroxide and metallic cadmium as electrodes</td> </p></span></td>
    • Difficult to be damage</li> </li>
    • High energy density</li> </li>
    • Lower self-discharge rate in comparison with NiMH</li> </ul> </td>
    • Suffers from “the memory effect”</li> </li>
    • High environmental impact</li> </li>
    • Highly toxic</li> </ul> </td> </tr>
    Nickel-metal hydride (NiMH)</span></p>

    Uses a hydrogen-absorbing alloy instead of cadmium in the chemical reaction</td> </p></span></td>
    • Has higher capacity and are less toxic than NiCad batteries</li> </li>
    • Longer lasting than NiCad batteries</li> </ul> </td>
    • Suffers from “the memory effect”</li> </li>
    • Can be damaged because of the complete discharge</li> </ul> </td> </tr> </tbody> </table>

      Also, some laptop batteries are non-removable (like in MacBook Air and Dell Adamo). If you have such a battery, it is almost impossible to replace it, but laptop producers decide to make the batteries non-removable, because it helps them to make a laptop thinner and lighter for you.</p> </p>

      How to define battery of what type does your laptop have?</h2> </h2>

      Well, there are several ways to do it. Firstly, you can search for your laptop characteristics description and find the battery type there. Secondly, you can disconnect your battery (make sure the notebook is switched off and unplugged), battery type is usually shown there. Thirdly, you can download special software which can show you what battery is used in your device.</p> </p>

      Device for testing a dead battery</h2> </h2>

      It’s very easy to test a dead battery if you have a special device. You need to search for universal laptop battery tester, there are plenty of options on Amazon. The device is quite simple, but not less useful because of it. It looks like a multimeter and can be attached directly to a battery or to a laptop. With the device, you also get a software to read indicators on the computer.</p> </p>

      The device allows you to study a lot of important indicators, such as battery voltage, current battery capacity, full charged capacity, current capacity percentage, charge/discharge current, charge/discharge cycle count. Using them, you can make a conclusion about your battery state.</p> </p>
