The length of time a battery handle will power the Wispr depends on the type of handle and the age of the battery.
- We have found that a new and fully charged Welch Allyn Lithium-Ion handle (Welch Allyn 71900 series) will power the Wispr for about 2 hours of continuous use.
- A fully charged Nickel-Cadmium battery handle (Welch Allyn 71670 series) will power the Wispr for about 30 minutes of continuous use.
Since the average ear exam is less than 10 seconds, both of these handles with new batteries should be able to go the entire clinic day without needing to be recharged.
