Will low batteries cause my Truncheon to read inaccurately?

A. No. The Truncheon is designed to give accurate readings until the batteries are fully exhausted. The Truncheon will give accurate readings until the batteries have insufficient power to light the LED's. Expect up to two years battery life with normal use when using quality standard batteries. Remove all batteries if the Truncheon is not in use for 6 months or longer. Remove and replace all batteries when discharged or any corrosion / swelling is evident.
