Do-it-yourself laptop battery repair often involves replacing the batteries. You can buy new identical cells or choose the best of two old laptop batteries. Do-it-yourself laptop battery repair consists of the following steps:
- First, let's disassemble the battery. To do this, you need to open the two halves of the plastic battery case. They are held on by latches in the contact area and glue around the perimeter. First, we pass a sharp object along the perimeter to tear off the glue. Then we separate both halves and the latches at the contacts will open on their own. Inside the case there are 6 elements and a controller that controls their charge and discharge. The batteries are connected to each other by tape using spot welding.
- Unsolder the wires from the elements and disconnect the temperature sensor (don’t forget to draw a diagram of the battery connection before repacking or take a photo)
- We choose the best batteries from old batteries or buy new ones, tin the contacts of the batteries and contact plates (if they break during dismantling, then we use copper foil).
- We solder all the batteries into one block according to the diagram (we work with a powerful soldering iron at a temperature of 350 degrees Celsius for no more than 2-3 seconds)
- Solder the control board to the battery pack from lower voltage to higher voltage
- We pack the battery pack into the case and connect it with tape or super glue.
- Connect the battery to the laptop and charge it fully - discharge it 2-3 times.
In my case, replacing the cans of the branded Asus A32-1015 battery did not bring a significant increase in performance (you need to reset the controller parameters to factory settings using the adapter and program). Replacing battery cans - copies of "Replace A31-1015", "A32-1015" ended in success, the battery began to work for 3 hours with high performance.
