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.

The use of low cost carbon-zinc batteries is NOT recom-

mended.

Nickel-Metal Hydride Batteries: These batteries can save you money in the long run, as they can be recharged. Typical battery life is about 90% of the length of time alkaline batter- ies last.

Battery Life:

TR-1

Alkaline, 8-10 hours typical

Nickel Metal Hydride, 7-9 Hours typical

WARNING:

Do not place an alkaline TR battery pack in any battery charger. Severe charger and battery pack damage may result.

Cold Temperatures and Batteries

The battery life times listed in this section are at room temper- ature. Alkaline and Nickel-Metal Hydride batteries service hours falls off significantly at low temperatures due to battery chemistry. Alkaline batteries typically have less than half their room temperature service life if used at freezing 32° F (0° C). Due to the service hours reduction of Alkaline and Nickel Metal Hydride batteries at low temperature the user will need to change batteries more often.

Another solution is using Lithium AA cells if beltpacks are to be used in very cold temperatures. Lithium batteries, like the Energizerâ E2 Lithium AA cells, are excellent batteries at cold temperatures. At the temperatures of 15° F (-9° C), Lith- ium AA cells will last about 7 times longer than Alkaline bat- teries. that equates to 2 hours for Alkaline vs 14 hours for Lithiums. However, the tradeoff is Lithiums cost more and are less friendly to the environment than alkalines.
