Often there are situations in which people after a relatively short use laptop begin to wonder how to restore the battery. Due to the fact that during the constant use of the laptop battery gradually loses its charge, and after some time it starts very quickly “sit”. In this case, many are sent to the store to buy a new one. However, it is not necessary. It is currently known how to recover the battery. The time it will take a little more, but will allow you to save money.

Before you restore the laptop battery, you need to understand what he types. Often use lithium-ion and Nickel-metal hydride battery. What type of directly your detail, you can read her body (Li-ion, NiMh).

To Start the recovery process it is necessary to disassemble the batteries. Most often designs they have is not collapsible, therefore, must be carefully using the knife to separate the glued two piece case. It is important not to damage the inner elements. Then it is necessary to determine the nominal voltage of the battery. If you have a Nickel-metal hydride, 1.2 V need to multiply the number of its elements. Then with a multimeter measure the voltage at the extreme conclusions of the group of elements having a serial connection (the load should connect the light bulb from the car). If the device displays a voltage equal to the nominal, but the laptop does not turn on, then the failed controller battery. If the voltage is less than needed, then measure it for each individual item. Then in order fully discharged each element, connecting the light bulb. Then charged with light bulb and power supply laptop. Consistently to elements plug-in bulb and the power supply, wait until every element voltage will be 1.1 V, and then plug a standard device for charging. Following discharge-charge done three times and check the battery life in the laptop. If all you made did not help and the battery is not “alive”, then buying new is unavoidable.

Before I tell how to restore the lithium-ion battery pack, it is worth noting that this type requires special care during repairs. The principle of verification voltages is similar to the previous one, only it should reach 3.7 V-4.1 V in each element. On the findings of the measured voltage with load car light bulb. 3.7 V multiplied by the number of elements. Compare the results. If they are equal, it is necessary to repair the controller. If the total voltage is less than the proper level, go to his dimension on every single item. Before the measurements of the parallel blocks should be separated, and unsolder the controller battery. Identify outside elements and change them to healthy. Before assembling and connecting the elements you need them to defuse. This can be done also with a light bulb. After the restore battery failed again to collect his body, proclaim glue to secure.

Sometimes a similar situation occurs with the car. The battery “fails” over and over again, and the new money yet. In this case, it would be useful to know how to restore a car battery. The reason for his failure often becomes a capacity reduction that occurred as a result of prolonged discharge. In such a situation helps long discharge-charge cycle. It is necessary to drain the old electrolyte and rinse the battery with distilled water. Then it is necessary to dissolve desulfating additive with the electrolyte and fill the battery. When these steps are finished, plug the charger in automatic mode, charge-discharge cycle, until the voltage increase to 14 V. After you must perform a charging cycle to the nominal voltage. The battery is ready for use.
