I had replaced the batteries in both my 102 and NEC 8201 with the capacitors. The NEC was just starting to corrode at the ends of the battery. I was thankful I caught it before it moved down to the PCB. The 102 didn’t really need to be done but I ordered 5 capacitors so I went ahead and did it. I had my 200 open because the AC adapter port was loose. It would wiggle up and down and only work part of the time. A simple re-solder solved that and I decided to swap out the battery with a capacitor while I was in there. But the 200 power circuit didn’t like the voltage of the capacitor so I just removed it and run it without backup. I run it 95% of the time off of AC and if I need to swap batteries without losing the contents I just keep the AC adapter plugged in and put in fresh batteries.

I haven't cracked this one open yet so I have no idea what the physical condition of the battery is. It did readily charge up though with no fussing. I would think after all this time I would have too little voltage going on here versus too much. (Assuming a previous owner hasn't fiddled with it yet.) Rick _____ My 200 didn’t want to power down when I swapped the battery for a super capacitor. Too much voltage so it never shut off. Just two lines across the screen. I ended up removing the super capacitor and now run it without a backup battery. That solved my problems. The power circuit is very sensitive to voltage. Kurt
