How to Repair a Laptop Battery ?

 


Like all energy storage devices, batteries that power a laptop eventually lose their capacity to hold a charge. Laptop Battery Repairing is generally more cost effective than replacing the whole thing because you can retain the digital circuitry that controls it. Laptops usually have a battery check program that enables you to evaluate the condition of the device. The program will recommend that you replace the battery when one or more cells have low capacity or have completely lost the ability to accept a charge.

Check the Battery Status

If the program to check your battery status is not already on your computer, you can download and install the appropriate program. After you run the program, the system will generate a report regarding the overall status of the battery. A single bad cell can shorten the total life of the laptop battery pack. If your laptop has multiple batteries, you must run the check on each specific one. Before you repair your laptop battery, ensure that you read and understand the terms of your computer warranty.

Drain and Remove the Laptop Battery

It is essential that you fully drain the battery before removing it from your computer. This ensures that all cells will have an equivalent charge when you install the new components. Use a screwdriver to remove the back of the battery pack. To avoid damaging your laptop, you must use power cells with the same chemical composition and power rating recommended by the manufacturer. Record the model number of the battery and the part number of each cell so that you order the correct replacements.

Remove the Old Cells

Use a utility knife to cut open the plastic that encloses the power cells. Before removing the power cells from the battery tray and disconnecting the lead wires, verify whether the laptop battery needs to maintain a charge in order to retain any data in a memory, such as the resistor value or fuel gauge function. In these instances, you must maintain a secondary power source to the circuit while replacing the worn out cells. Ensure that you disconnect and reconnect the wires in the proper sequence. This may require the assistance of a voltmeter to properly determine which are the positive, negative, clock and data connections for the battery circuit.

Install the New Cells

Place the new power cells in the tray, connect the electrical contacts and cover them with the plastic. Batteries normally remain in the correct position, but you may need to bond them into place if the wires were damaged when the power cells were removed. When soldering, it is critical that you avoid excess heat that can damage the cells or electrical circuit. Reassemble the battery pack housing.

Install the Battery

Determine whether your battery has an on/off switch. A laptop battery that cannot be turned on when the circuit is connected to a ground may require a special code from the manufacturer. Verify that the polarization is correct and that you are using a compatible charger. Use a slow charge if the cells have a different state-of-charge. Do not try to charge damaged cells or ones with different chemical properties. Fully charge the batteries before using the laptop.

Laptop battery repair

In a technological world, being connected is one of the top priorities in many career fields. Laptops are one of the many ways people work and communicate, so when laptop batteries fail it is essential to repair them quickly and efficiently. Repairing a laptop battery is easy if one has the proper know-how and tools to complete the task. By following some simple tips, laptop users are able to quickly get back into the game without having to pay for a new battery unit. Although repairing a laptop battery is a good way to save some money, users must take precaution when dealing with any electronic repair. Laptop batteries and repair supplies are available at electronic retail stores and online through sites, such as esanyog.

Repairing a Laptop Battery

The battery of the laptop is made of battery cells and a circuit board. Typical 6-cell laptop batteries have several hundred charging cycles, so after this tired, cells no longer have any charge. If it is in the case of someone's laptop battery, then the easiest way to repair it is to replace the cells. Although battery cells are available for purchase at a fraction of the cost of buying new batteries, it is best to avoid headaches for some time before working with electrons and waste money on battery cells and any related supplies. Should work to do

Removing the Battery

To ensure safety while repairing a laptop battery, one must take all the necessary precautions The first step is to ensure that the current laptop battery completely drains the power before removing it. After the electricity completely drains, the battery needs to be re-checked before the battery is removed.

Opening the Battery

To replace the battery cells, open the battery case to complete it, carefully open the case with the flat-edge screw driver and utility knife. Once the battery case is open, buyer battery type type analysis And what type of soldering need to be installed to set them up. A good tip is to take a photo or remember a diagram of setup where everything goes on. If cells and battery cases do not fit properly in the laptop, repair is useless, so it is important that users can be taken extra to stop the case when the case is opened.

Replacing the Cells

To prevent electrical shock, it is important to use voltmeter to ensure that old cells are completely removed. Using the soldering apparatus, remove existing cells from the wires before removing them. To find the appropriate replacement cells, use the model number on the battery pack. Combine new cells for stars, make sure to connect them with appropriate stars. The best way to ensure proper connection is to do soldering if replacing lithium ion cells, use safety glasses and handle with caution because they are capable of exploding. Once the battery case is closed and the laptop is backed up, the battery must be fully charged before using the laptop.
Smart Batteries

Some laptop batteries require a continuous power source to protect important data in memory. When replacing cells in these types of batteries, adding a 100-ohm resistor before the removal of old cells requires the secondary voltage provided. With the installation of new cells only the user can stop the resistor
