Battery Information

Improper battery selection, use, installation and care are the cause of numerous wireless system failures.

Alkaline Batteries: Alkaline batteries such as Mallory’s DURACELL® or Eveready’s ENER- GIZER® provide the most reliable operation in wireless transceivers. Typical battery life of fresh al- kaline batteries is 12 hours. The use of low cost carbon-zinc batteries is NOT recommended.

Nickel-Metal Hydride Batteries: These batteries can save you money in the long run, as they can be recharged. Typical battery life is 8 to 9 hours, which is about 70% of the length of time alkaline batteries last.
