so, i know the batteries to use are the 3.6v batteries, however, what is the rating to use. i've seen some for 600mah, and one for 1000 as well. i assume that's the rating for the battery to last between charges. so is it better to go with a higher rating?
 
Have you seen the tech article on Bob Robert's site? There's a detailed writeup on repairing these boards, and he mentions replacing that with a flat nicad battery. Read it if you haven't. Good luck-

yeah, i have. i have a couple cordless phones i don't use lying around so i figure i'd give one of these a shot.
 
I just wonder if they would eventually leak. I'm all for originality 95% of the time, but sometimes it's better to re-engineer or improve on the design.

I'll be rebuilding one of these for a Tapper, so I'm interested in what you end up doing.

Bob uses lithum....kinda different from nicad.

I tried using a cell phone battery and also a lithium ion battery, neither seemed to hold the scores for more than a couple days. So I switched to the chip swap option.

I know there is a post from Matt Osbourne about using a battery backed up RAM chip in place of one of the 6116 chips in the MCR board stack. It's worked for me for over a year without any problems.
 
cool. i think i'll try the battery backed ram and see where it takes me. rather not shell out a ton of money on stuff that might not work.
