Battery for PowerBook G4 titanium mercury (500mhz)

[2tmb]

I have a PowerBook G4 titanium mercury 500mhz, but the battery for it is dead. Because of this, whenever I want to use it I have to keep it plugged into the wall, unlike a traditional laptop. I recently updated it to macOS 10.4 tiger, and put a bunch of emulators on it, so I think it’s finally at the state where it would be useful to be able to carry it around. I need a “PowerBook G4 Rechargeable Battery” with a model number of M6091. I have been looking around sites like eBay, but I am unable to find many of them for sale, and I am unable to determine by myself if they are at a good price point considering I have never looking into this before (the PowerBook g4 was my first PowerPC computer). The best one I’ve found so far was:

Apple PowerBook G4 Rechargeable Battery M6091 as Is for sale online | eBay

Find many great new & used options and get the best deals for Apple PowerBook G4 Rechargeable Battery M6091 as Is at the best online prices at eBay! Free shipping for many products!

and I would greatly appreciate any advice on if this is a good deal or not, and if you find a better one, I would greatly appreciate if you would include the link.

thanks for your help!

I would investigate rebuilding your battery. It almost certainly contains regular off the shelf rechargeable cells that you can get from any electronics shop. If you can't do it, you may know someone who can.

@barbu Unfortunately I am unable to open it, and it uses a proprietary connector.

You misunderstood. If you search, you will see that one can open it and it contains common replaceable cells.
OWC used to sell batteries for ancient laptops but I doubt they have any left for PowerBooks. And the cost was alarming when they did have them. Anything sold on eBay or whatever will either be a cheap knock off or will be twenty years old.

I would give these folks a call: http://resale.headgap.com/. I've never personally purchased from them, but when I was looking for a 17" Powerbook battery a few years back, they were the only store I found where I could buy a brand new one for under $200. Didn't end up purchasing, but they certainly seem legit.

@dbdjre0143 thanks for that, I’ll check it out.

@barbu, I attempted to open the battery but I accidentally sliced through the circuit board, so I’ll have to get a new one. Also I don’t see any way to close it back up even if that didn’t happen. I’ll attach a picture.

I salute you for trying! That’s bad luck with the ribbon cable.

@barbu thanks. I also cut a hole in the actual control board, so there is definetly no salvaging this one.
