Li 2032 on older style, non-GPS computer will last 5 yrs or more. Older computers may respond to battery change and dsbrantjr suggestion of
cleaning the contacts, both in the battery compartment and on the slide in contacts on the removable computer back and the mount may
help. I have had this occur with one computer (random speed jumps, ie 11 to 23mph then 14 while moving on the flat). Hope you can
interpolate your odometer reading, if important to you, as removal of battery or reset push zeros out all the settings. Computer should
work down to 2.2V out of the battery (2032 is 2.8-3.0VDC when new). The graceful fail of low battery is a dimming display. One computer
needed the battery contacts bent back into a good position, they were too depressed to make reliable contact with the 2032 cell and the
vibration resulted in intermittent contacts. All of my computers are 8-12 yrs old. Failed computer most commonly manifests as
no display.
