Laptop battery drops to 0% randomnly

[Agena_]

I bought a preowned lenovo 530s laptop, seemed good when checking it out, had windows 11 which i then downloaded windows 10 on
came home and set windows up, an its full charge captain was only 10.4 out of its original 45.45wh.
 

So I still used it for 2 days while waiting for the grade B official lenovo battery i ordered from ebay.

i switched them, and i charged the laptop to 100% with the new battery, used it for 3 mins then it suddenly dropped to 0% and laptop died. Thought it might be a one off thing.
so i recharged to 100%, used for 20 minutes, battery was around 65% and it dropped to 0% again.

So i switched it back to the original battery i bought it with because that would be better to use and the same thing happened. after about 30mins of usage, it dropped to 0% and shut down.

windows says its updated, lenovo automatic driver update on browser says everthing is updated.

 

How can i fix this?

(I've got the latest bios version and now im writing this with it plugged it in, laptop is at 14% and im guessing as long as i use it plugged in it shouldnt randomnly shut down to 0%)

Batteries are shot or dead.  This is usually the issue.

that's what I assumed, but im scared its not
as the original battery that i bought from the other person i used it for the weekend and it never did that issue. but when i got the new battery that issue started, and i thought it was the new battery fault. but now the original battery has the same issue

Is there anything during battery change that couldve caused it?

if both batteries are 5 years old like the laptop then it makes sense they dont hold a charge

Had a battery on an older HP that would (somewhat) randomly just die and power off, turned out to be the battery management chip was fried since the battery level after power-off would jump randomly, got a new real battery and it was fixed (also happened to gain capacity because battery tech)

Keep charging and discharging the batteries.  If they are fully charged in 1h 30m, then only charge them for one hour tops.  Then only discharge them for less time than you charged them.  The idea is to not get the charge level very low, and to attempt to use the cells that do still work and hopefully it will eventually learn how long it can stay on.

 

A website called battery university has a great explanation of why it is not ideal to keep lithium-ion battery anywhere near full charge, especially overnight.

Try the two batteries you have for a few weeks, and if they still can't hold a charge, the charging chip may need a few fresh charging cycles to re-calibrate itself, or whatever it may be doing:

So keep trying to charge it, and it may be that it has lost some capacity, but let's assume the battery capacity is higher than 25%.  I just find that a bit low for only a few years.  Even if it IS a low 25% capacity, it should last more than 20 minutes.  This would mean the battery, when new, could only power the computer for 80 minutes, which is quite low for a fairly new system.

 

I have a laptop from about 2012 or so, and the battery still powers the laptop for nearly two-hours, but I only let it run down to 40% and I try to unplug the charger when it gets near 70%, still giving me an entire hour of battery runtime.  It really is not great physical effort to get up and plug in the charger into the outlet, and also to the laptop.  My setup with pi-hole usually has an issue with the wifi disconnecting after about 30 or 45 minutes (could be too many constant block requests at over 900 per minute at times) so I'm up anyway, resetting the network settings in virtualbox, and then turning on the wifi again.  It's probably a wireless aoftware issue on Windows.
