When using a Kestrel Wind Meter, you need to avoid Energizer Lithium Advanced Batteries. The only batteries we recommend are Ultimate Lithium Batteries. The reason being is that the Ultimate Lithiums have a lower magnetic signature. The Advanced Lithium have a high enough magnetic signature that they interfere with the Compass Calibration, and can cause errors.
DO NOT USE ADVANCED LITHIUM BATTERIES IN THE KESTREL, ONLY USE ULTIMATE LITHIUM
