What is the battery life expectancy for the 2100Q?
2100Q battery life
The battery life expectancy on the 2100Q is between 80-160 days under normal use (approximately 10 readings per day, using backlight). If the batteries are only lasting a few days, first check for corrosion in the battery compartment and make sure good quality alkaline batteries are being used. If this does not fix the issue, it could be that the main board has failed. Please contact Technical Support or the Service Department.
