MSI Laptop Battery Stops Charging at Random Percentages: Windows 7, BatteryCare, 22.2W, 11472mV

Hello, I have an MSI laptop. It is a 5 year old laptop. I replaced the battery a few months ago. The problem is that the battery sometimes charges up to 43% sometimes to a different value. I waited for the battery to discharge and started charging from scratch, but still the same. Today it even stops charging after a few seconds. If I disconnect and reconnect the cable, it recharges and stops in a few seconds. Windows 7, at the bottom corner where we have the battery icon, you can see how the battery is a plug and it is written (connected, charging). During these few seconds of charging on this icon you can see the increasing battery level and then just stops filling up but it is still written that it is charging. It happens that suddenly recharges a few percent and stops. I installed BatteryCare. Charging speed 22.2 W, voltage 11472 mV. Do you have any idea how to try to fix it without buying a new power supply and battery?

Unfortunately, most likely the battery was damaged (cells or there is a problem with its electronics), did you buy a replacement or the original battery?

If you have a guarantee, advertise because you will not do much. Probably one pair of cells or even one 18650 cell has fallen and the electronics cut off the power supply. If you don't have one then you only need to replace the damaged cell and the battery will work.

Replace the damaged link - nonsense. Tell me how do you want to match this link with the others? The one cell mentioned will differ in relation to the other in terms of capacity and internal resistance. Such a cell will want to be charged when the others reach their maximum charge or it will charge to the maximum when the rest is still charging. Similarly when unloading.

To replace the cell at home, you need a modeling charger that measures the capacity of the cell. The link is best exchanged for one with similar parameters, the easiest to choose used. Nobody promises that the battery will last two more years but it should last a few months.

Hello.
I would like to join the topic because I have a similar problem. The battery from my Toshiba Satellite C66D laptop stopped working a long time ago and I decided to replace the cells. The battery has 3 pairs of cells and only one is functional. I bought 6 Sony cells with parameters as close as possible to the original ones, combined them into packages as it was factory-made and put everything together. After inserting the battery into the laptop and connecting the charger, the orange charging LED lights up for a few seconds and goes out. The laptop on such a "charged" battery moves for a second and turns off, when I turn it on on the battery and charger then it normally turns on but after disconnecting the voltage from the charger it turns off immediately. The battery is also not detected by the system. Is there any way to initialize the battery in this case or reset the electronics? or is there no way to fix this fault?

I had this problem with a Toshiba L50B. When all attempts to regenerate the battery described on the internet failed, I dismantled the battery. The individual cells had a voltage of 3.3V 3.3V 2.7V 3.0V. I charged two undervoltage cells to 3.3V. After installing it in the laptop, the battery started working properly. Earlier, using this method, I regenerated the battery in my electric bike.
