Battery Full Charge Capacity Extreme Degradation

I'm reading some other topics on here where people are worried about a 10% loss over 10 months.

I have bought and returned about five batteries now, all of which degraded by 40% over a week, and my current one by 70% over 2.5 months.

I have contacted Lenovo Support who only offered a ludicrously expensive repair service, and the seller I bought the batteries at also refuses to support my issue any longer.

Why is this happening? How can I fix it?

I always charge and discharge 20-80% and never leave it plugged in overnight.

ThinkPad Edge E531.

 

PS: Since my first post 6 days ago it has degraded further with 1300 mWh.

Re: Battery Full Charge Capacity Extreme Degradation

Please help if you can. My 3h battery is down to about half an hour now after only 3 months.
