| PowerBook 500 Series Powerbrick Replacment |

Recently picked up a PowerPC 540C from a friend, who had cut off the original power brick and replaced it with a generic 16V supply. I’m currently looking at his work and I’m curious on if I could just attach both the battery wires and the main power wires to the same 16v supply.
I don’t think anyone has done it, only theorized about it, but I wanna check in with others to see. Has anyone attached the two wires to the same supply? |

From what I understand, this would be dangerous. I think the battery charge side of the original PSU is intentionally limited to 1A. |

Yeah I’ve been reading through your guys attempts on reviving the batteries. Good thing I didn’t wire it, guess I’m gonna have to find a 15v 1A brick and add that for charging the battery. |

Yup, what @croissantking said. My bricks are two PSUs in one.. the battery side limited to 1A. |

I'm gonna have to have a go at this sometime. I've got 2 full working 500 series, and a bit of a messy one, but only 1 PSU between them and I bet it's gonna go pop soon. |

I’ve got two original power supplies that’ve been recapped and they seem to be holding up quite well. |

I’ve got one I made and one original recapped. The recapped one was working fine for a while but then all of a sudden stopped working. I had resealed the plastic housing so need to open it at some point and see what happened inside. |
