Is that one of the original Apple batteries or one of the aftermarket ones? That is really good runtime, either way! I have found that my VST aftermarket ones can't use battery recondition, the computer goes nuts (starts clicking and beeping after about 20 seconds of the white screen...it freaked me out). I get a bit more runtime from the VSTs than the Apple ones, but no more than 20-30 minutes. I just think of these as plugged in machines and use the batteries like PRAM...

I wish it was easier to find old RAM for the 1400...not much around on the 'bay anymore...I have two 24MB cards so I have one of mine maxed to 64, but that leaves my other ones with only 16. I'd love to find some more 24 or 32 MB cards...
