How long do the batteries last?

High energy batteries last approximately 500 tests or 1 year. 

The number of tests may be reduced when the measurement frequency is extremely low (one test per week) or the meter is left unused. Setting the display brightness to level 3 and the beep volume to level 4 or 5 or using the acoustic mode permanently also impacts battery life time negatively. The number of tests may be improved when the test frequency is high.
