PowerBook 145 Battery

[loplop]

Hello, all! I have enjoyed putting my original SE back to work so much that I have a nice PowerBook 145B incoming for a mobile setup. I would like to get a step ahead with a fresh battery, as I’m sure the original is toast. Ive done some searching here and see references to a 3-d printed battery tray that holds rechargeable AAs, as well as some references to disassembling the stock battery and soldering in nimh AAs. But I can’t find detailed threads on either.

Tips welcome, and if there’s a better suggestion, I’m all ears!

As I'm on the cheap side, what I did was to open the case, remove the old (and spilling) cells and put a 6V AA package on it. It only keeps the charge for well less than 30 minutes (I have a BlusSCSI), but it's just for the fun of having it on battery.

(I tucked a thermo-fuse under the wrapping)

Thank you for the suggestion! How did you open the battery? It looks like the two halves of the plastic case might be glued?

Mine is toast—I can’t get it to hold a useful charge at all, sadly.

Yes, it’s glued. I used a cutter and some patience… the plastic is not too thick in the joint of the two sides.

Thanks! I’ll have a go…
