Batteries
Kestrel Weather & Environmental Meters require
2 AAA batteries. Average battery life is 300 hours
based on typical use. Lithium batteries are strongly
recommended.
*For the Kestrel 4500 & 4600, it is important to re-insert the
shim along with the new batteries then re-calibrate the
digital compass to ensure correct wind direction readings.
When using the Kestrel Meter in extremely cold weather,
it is recommended to use lithium batteries for optimal
performance.
Maintenance & storage
To avoid scratching the window, store the Kestrel
Tracker in the soft pouch.
