I gave up and after few months i contacted the seller again and got 3rd battery but it has the same issue.Īnd so i was wondering if all three batteries are faulty or did the swollen battery damage something inside the laptop and if yes then what did it damage and is there a fix for it. I contacted the seller and they send me a new battery. I read about the issue and it seems to be faulty battery. After a few cycles it is already under 60% health. When i got the battery and installed it in the laptop it worked but when you let the battery discharge it will jump from 50%-70% to 7% and stay there for a while and the battery maximum capacity goes down. Battery type: Li-Polymer Capacity: 77.5Wh Voltage: 10.95V Grade A cells ensure fast charges and low power consumption Built-in circuit protection ensures. Everything works good and so i decided to buy a battery for it. I removed the battery and bought a charger and run the laptop without the battery.
