So I almost never use my G3 due to the lack of power. It's more of a desktop now since I don't really bring it with me either. Since my only PBG4 doesn't have a battery, I decided it would be better put to use in that. I also plan to take my PowerBook with me to school,etc. Most of you know that NuPower batteries are expensive, which I don't have 80+ to shell out. Then an idea popped in my head, why not use my G3 battery in my G4. I proceeded to take apart the battery till I was left with the internals. The battery fit snug in the battery compartment. I then started to seal it. I didn't have electrical tape so I used metal tape, LightBulbFun pointed out that it could short out the battery so I needed to insulate it. I took an old video game case and cut out the plastic to fit the battery compartment. I then taped it using metal tape. The dirty job is done. Now I realize that I took apart a perfectly fine battery. By all means, rant about it but I feel it was better than it sitting around doing nothing. Selling something would be a process due to my parents. And here's the end result. All in all, it feels solid and not loose. I am aware it's not pretty but I don't care much about that as long as it portable.
