I do have a Ni-MH battery so memory is not an issue, there might be a multimeter in my garage so I will do this sometime this weekend. I will also be fixing up my PowerBook 145B because it does have a good PRAM battery. I just want to know if I had to replace the PRAM battery, could I do a quick and dirty way by finding a replacement battery with the same voltage, make a mini holder for it and then hook it up to the solder points with wire?
