Twice bought cheaply and then again landed at Sony.

I've waited a long time but here's my first review, probably to warn and on the ground to others from what happened to me.
In notion of an alleged Schnäppchens and the upcoming holiday travel, I acquired the presented battery as second battery for my PSP Slim & Lite.
After I had inserts it into the PSP, and the charger was joined, once a battery charge of 95% was shown a little later it was 100% and the PSP turned itself off. When trying the PSP without launching charger I had then the fetstellen because nothing went.
Multiple tested always showed the battery pack with charger 92% - 100%. But without charger showed the PSP no function.
The battery was replaced after complaint immediately anstandlos by new which was great it must be said, but this also showed the same Sympthome. So all in alem a letdown.
I ordered then at another online merchants a battery pack with the same specifications as Sony also suitable for PSP 3004 according to the description (PSP-S110 - Battery for Sony PSP Slim & Lite (PSP-2000 / PSP-2004) / PSP-3000 / PSP-3004).
Also this showed the same properties. The I after complaint as a bargaining chip by the way got. Bought So back to the original Amazon and Sony. He came to 0% of battery charge and now loads without any problem.
From my perspective I can only guess who the PSP 3004 Slim & Lite calls his own should only the original battery's buying running at least albeit at a higher price.
