HUAENG Battery for Gameboy Advance SP(GBA SP), Li-Ion Replacement Battery with High Capacity for AGS-001, AGS-003, AGS-101 Tools Included

Works as expected, easy installation and bought my Gameboy SP back to life.

Der Akku passt perfekt als Ersatz. Die Kapazität ist größer und man hat ein längeres Spielvergnügen.

I already knew that 1600mAh is impossible with this battery's size. It's simply not possible currently to pack so much energy with this battery's size. But the question was, how good is it actually?I did multiple tests with a GBA SP that has a IPS v5 mod on full brightness and using a EZ-Flash Omega DE card. I ignored the first full charge-discharge cycle. I will compare it to an original SP battery, I have 2 but they had around same result so I will include 1 for the results. I also checked the mAh going through the cable when charging after a complete discharge. There will always be some loses because of the cable + getting the energy into the battery, so the actual capacity will be bit lower.HUAENG (this one) battery:Red light: 2 hours 15 minTurned off: 3 hours 22 minCharging mAh: 803mAhOriginal SP battery:Red light: 1 hour 26 minTurned off: 2 hours 50 minCharging mAh: 607mAhIt did beat the old original battery and I would say, it's one of the better batteries sold on Amazon. Only issue I have is the false information about the capacity. I get it, they all do it, but I think you can better be honest and sell it as a 800mAh battery. This is also the reason why I gave it 4 stars, cause the capacity is half what they advertise it has.Would I advice it if you really want to buy a battery from Amazon? Then yes.

Me dura el doble que la batería anterior que tenía.Tenía una batería nueva de 850 miliamperios y jugando a Pokémon me duraba 1:10 hora.Con esta batería de 1600 miliamperios ahora me dura el doble así que cumple su función.La recomiendo.

passt anstandslos, der Tausch dauert nicht mal eine Minute. Zur Kapazität kann ich noch nichts sagen, aber wenn ich nichts an der Bewertung aktualisiere dann wars wohl Top.
