Carbon-zinc batteries are the least useful for wireless
microphone operation. Their low cost is more than off-
set by their extremely short operating and shelf life.
Although the “heavy-duty” (HD) carbon-zinc types offer
better low-temperature performance and service capaci-
ty at moderate to high current drain, they will not offer
appreciably better transmitter performance than stan-
dard carbon-zinc batteries.
Although battery operation is inhibited at low
temperatures, storing batteries at low temperatures will
increase their shelf life. They should be sealed in bags
and, when ready for use, allowed to warm up to room
temperature (never heated!). Cold-stored batteries
should be used as soon as possible after bringing up to
Battery life is shortened by storage in high-
temperature locations such as on amplifiers or in
vehicles exposed to direct sunlight.
