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 ENERGIZER® provide the
most reliable operation in wireless transceivers. Typical bat-
tery life of fresh alkaline batteries is 12 hours. The use of low
cost carbon-zinc batteries is NOT recommended.
WARNING:
Do not place an alkaline WTR battery pack in any battery
charger. Severe charger and battery pack damage may result.
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.
