My battery health raised from 7.5%(was going to replace it soon) to 1489.2%. What should i do or should i be concern about it? It happens after the laptop suddenly shut downs.
Well you have more than just a battery issue if your laptop suddenly shuts down. I would replace the battery since clearly you can't have an over 1,000% battery health. Then look into why the system shuts down if a new battery did not fix that, could be a heat issue or motherboard issue, failing RAM or video card, etc..
