| Powerbook Duo Battery Pack types and compatability |
Posted by: Sideburn on 2024-03-15 12:37:33
Hey All,
I rebuilt a test pack for my 2300 and, although it is charging it will not power the machine. it shuts down immediatley when disconnecting the external A/C adapter.
Are the battery types not interchangeable between Duo versions?
I have two packs. One is a model #M7782 and the other is a #M1499
I reebuilt the M7782 pack and I know this is a Type one pack used in the PowerBook Duo 210/230 series originally. Will this pack not work in a PowerBook Duo 2300c?
And is the DS2400 DALLAS SEMI Memory Circuit important? I assume this is used to identify the battery pack type. |

Way back I had a Duo 280 and my Dad had a 2300 we had four batteries between us that we just shared and never had any issues. At least one of them was a Type 1 as had a 230 at one point since that's when he bought the Duo Dock. The battery I recently rebuilt is a type 3 and I did keep all electronics intact. I didn't fully stop using the 2300 until the 12" G4 came out. |

Thanks for the info. Might be my powerbook then. I wonder how crucial that like ID component is. I ownder if you were to just supply 12V to the far ent terminals if it would boot normally. Mine doesnt. |

I'd assume the ID chip is required. |

I'd assume the ID chip is required. I'm almost positive you're right, I remember running an app every so often that would drain the battery and reset them. |

I opened the 2300c up and set my bench supply to 1.6A / 12v and connected to the battery terminals direct and it would not boot. Then connected the ID chip and it booted right up. |

Finished my pack. Used ternegy 2000mah AA nimh and get 2 hours at full discharge. Now I need to figure out how to replicate the serial off the DS400 so I can make more. |

Great work! Now if only the PB500 series batteries had as simple electronics. I had four batteries but the corrosion was so bad in all but one had a salvageable smart board. |

Ahhh. Bummer I don’t have one of those anymore to even try. I had a 540c but sold it a while back. Yeah those smart chips are a big hurdle to get through. The next one on my list is the Pismo / Lombard.
In these duo packs, they’ve got a DS400 in them that had a unique customer ID and serial number i then that the PowerBook reads and if it’s not a matching ID, it won’t boot off the battery.
I found some info online on how to read this 64 bit ID using an arduino. But haven’t found a solid way of emulating a DS2400. There’s some forums talking about doing it with a pic chip and some on how to with an arduino but one problem is there’s barely any room at all in the pack.
If I could crack this hurdle I’d make some more… |
