Re: 15C short battery life Message #3 Posted by paul spiro on 10 May 2010, 8:42 p.m., in response to message #2 by Steve Simpkin
thanks for the response, Steve. The 2 sets of batteries were different brands from different stores and tested fine before installation. The cont memory was already cleared from sitting w/o batteries for a few days but I threw batteries back in and ran the ON/- and ON/x tests anyway.
however... the ON/x test showed that the bottom 2 vertical elements of the penultimate right-hand digit were missing. A little experimentation revealed that unless those final 2 digits were displayed all seems fine. As soon as I display the last digit or two the display noticably dims. I'm thinking my problem is not the power capacitor but an internal short in the LCD display.
I'm going to try running the calc w/o those last 2 digits and see if that solves my battery drain. I don't suppose parts are still available? (I was hoping it was just the cap...)
