Reasonably priced and fast delivery. Replacing the battery also worked without any problems.
Although the battery life is much better than before and use without a charging cable is possible again, the performance has unfortunately deteriorated significantly after just a few weeks. A few hours without a charging cable are still possible, but the battery discharges more quickly after prolonged use.

Top, I was able to replace the battery which was dead, it works well for now, very happy. HP customer service told me that there was nothing we could do...and everything was done so that we couldn't change it, thanks for the ecology.

The battery was used as a replacement for the original in an HP laptop, HP Pavilion x360 Convertible. It fits without any problems, the device works perfectly again. It is currently not possible to assess the operating time and durability.
