Based on another review I was excited to see how much the battery weight compared to the original. It is a slight difference but I wouldn’t say half the weight like the other review. How ever I went to put the battery into my psp and could not get the battery cavity cover back on. And it wouldn’t turn on. Idk if this was due to the battery being dead on arrival or what. But I couldn’t get it in to charge it. PSP wouldn’t even turn on. So I swapped back the original PSP battery. Plugged in the charge that came with this bundle and it did fully charge my psp. This was 3 days ago. An np exaggeration here. ( I haven’t got to play much) but my battery is still kicking and healthy. Funny thing is the day before I got this package in the mail I was returning home from a trip and was given the actual charger by the person who gifted me the psp. Haven’t tried it yet but I’m sure original power is just as good as it ever once was.
