PSP Fat 1000 1004 Classic, 3600mAh rechargeable battery for 1.Generation Battery Pack RBrothersTechnology

My original battery has unfortunately the spirit aufgegeben.Dieser third-party replacement is only conditionally recommended.
The battery life (although it is twice as long as is keeping the original), was with me only about 2 hrs., The
Maturity when old original was more than 4 hours.
On the other hand, new firmware updates with new games without battery therefore, can be loaded for example with power supply does not remain a possibly nothing else übrig.Sony manufactures no more batteries for the old series.
A similar battery of another company (both made in China) with the same technical spesifications had the
same result.
