One of my laptops had no battery time whatsoever - at all. it would turn off the moment the power connector was plugged out, even though OS reported full charge. Sounds like the battery is completely dead - or is it? The real problem turned out to be quite different from what I originally thought. I bet your guess would be wrong, too ;) Check out to find out what it was!
So this time around the subject is Acer ES1-531 laptop, though this issue is applicable to wide variety of Acer laptops, and probably some of the other manufacturers as well. In this video we'll open up the laptop, take the LiPo battery out, tear down the packaging to poke around inside the battery pack (DANGER WILL ROBINSON!) We'll find out what the issue really is, fix it, reassemble everything back and test the end result. Perhaps explode something, I don't know ;) This and a lot more you can find in this video (use the chapters if you want to jump to a specific section)!
If you're working with LiPo batteries, be very careful and make sure you're doing it as safely as you can. There is a mandatory disclaimer that these batteries are potentially dangerous - they can release toxic fumes, ignite or even explode. So don't do it unless you're certain that you can handle scenarios like that. You have been warned.
