Hey Bought a laptop on eBay 3 weeks ago. Seller was in the description, battery changed 3 months ago, little used. Now I have to find out that the battery goes from 100% to 0% within 20-30 minutes. This can't be. The battery has approx. 5000 mAh
Is that a flaw? Can the KV be challenged? (Private purchase)
Write to Ebay. They can help you further. This is not normal at all.
That is a shortcoming. However, a defect does not make a sales contract voidable.
What does ebay have to do with the matter?
He bought it on Ebay… Buyer protection and such ;-)
You first complain about a material defect to the seller.
Nevertheless, it is not wrong to write to ebay and ask how to proceed if you have not yet had such a case.
So 3 months ago the VK exchanged a weak battery for an even weaker one, and then used the notebook little because the battery life was so modest.
That is how you can interpret it.
Do a few charging cycles, maybe it will get better. I don't think there's anything that can be challenged. You can try it, but I wouldn't invest money (lawyer).
