We would recommend you carry out this method, regardless of whether or not any of the other methods already worked for you. This method involves having to examine the current, voltage, and watt hour ratings on your physical laptop battery.
If you are able to remove your battery from the laptop, then do so. Otherwise from what section of the battery is visible try to examine the text on it.

There’s no knowing how reliable these actually are. They might blow up one day, or end up frying the internals of your laptop. Trust me I speak from experience. So be sure to always buy an authentic battery, even if it ends up costing you a lot more.

How To Install A Brand New Battery
Now comes to the part of actually removing your old battery, and installing a new one. This can be a 30 second procedure if your laptop has a removable battery. Or it could take upwards of 3 hours if your battery is literally glued to the chassis like it is in macbooks.
Now if you do have a removable battery, the procedure is pretty simple.
1. Turn off your laptop, and disconnect the power adapter.
2. Release the locks on the underside of the laptop that hold your battery in replace.
3. Now slide your old battery out.
4. Take your replacement battery, and slide it into the compartment until you hear an audible click.
If your laptop has a battery that is easily accessible, and removable after your remove the bottom panel. Then you can replace this battery at home pretty easily too.

Now if you happen to own a modern day MacBook, or a thin and light windows laptop that has its battery essentially glued to the chassis. Then we wouldn’t recommend attempting to replace the battery by yourself, even if you are experienced in laptop repair.
It would be much better, if you sent the laptop in for a battery replacement. If you own a MacBook, then simply take it to the nearest Apple Store.
They’ll replace your battery for a decent-ish price, and won’t actually end up damaging the internals like you might have if you attempted this repair.
