A83: ION and new batteries VERY WEIRD


 I have a TI83 (not plus), its batteries were running a little low so I decided to change them.  I took out the old batteries and put in new ones.  After having done this, I ran the ion program (A) on my calculator.  The graphics in the ION program (ION v1.6) select screen were garbled, the graphics are disfigured into diagonals.  Like this:

normal line: 




------------

disfigured line:
    -
   -

The graphics seem to form 12 columns, the first column in place, the second placed higher, the third placed higher, etc. You can still use the arrows and choose programs with enter.  When you run a program, its graphics are garbled too.

I then put back in the old batteries and tried ION again.  With the old batteries in the calculator, ION was fine, the graphics were normal.  I found this to be really odd, so I did some experimenting, this is some of what I found,

-Only ION gets messed up, non-ION programs work fine.
-Besides one set being old, and the other being new, the batteries are almost identical.  Both sets are made entirely up of AAA Energizer Alkaline Batteries that have self-test strips on the side.
-When mixing in the new batteries with the old, the more new batteries in the calculator, the more garbled the ION graphics get.
-I had thought this might be the problem since the new batteries put the calculator at a lower contrast than the old ones but changing contrast without changing the batteries did not mess up ION.
-I also have a TI83plus, I put the new batteries into it and ION was fine.
-I tried resetting All Memory before I changed batteries and before i installed ION, but it didn't help.

I've actually had some problems with ION having garbled graphics in the past, but I was never able to link the garbled graphics with anything I had done.  The problem later went away by itself somehow, and ION worked fine.

In this instance, however, I am almost absolutely positive that the problem has to do with the batteries, but I'm not sure exactly what the problem is.

Has anyone else experienced a similar problem with ION?  Can anyone tell me how to fix this problem?

Sorry about making this message so long, but I thought this problem was very interesting and quite strange.
