BATTERIES
Careful battery selection, installation, use and care
will help avoid problems in wireless microphone use.
The optimum combination of reliability, long life,
availability and low cost at this time is the manganese-
alkaline, or alkaline, battery. A word of caution about
alkaline batteries: they are
not
all the same size. Make
certain the battery you buy will make contact inside the
battery compartment.
Nine-volt lithium batteries offer greater service life
and greatly increased shelf life over comparable
alkaline batteries.
Nickel-cadmium (nicad) batteries offer convenience
and long-term economy, but the tradeoff is in shorter ex-
pected life per charge. In addition, forgetting to
recharge can be disastrous.
Another major consideration in nicads is that of
operating voltage. The “heavy-duty” 8.4-volt nicads are
satisfactory for use in this microphone, but the “9-volt-
size” nicads commonly found in stores supply only 7.2
volts and will not provide satisfactory wireless perfor-
mance.
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 stand-
ard carbon-zinc batteries.
A l t h o u g h b a t t e r y o p e r a t i o n i s i n h i b i t e d a t l o w
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
room temperature.

The battery should be removed if the microphone
malfunctions, or if it is to be stored for a long period.
Most batteries have a protective jacket, but partly or
completely exhausted batteries are more prone to
leakage.
Do not attempt to recharge replaceable (primary) bat-
teries using “chargers”, heat or other methods. This
may cause leakage or explosion. Do not disassemble
batteries or dispose of them in fire.
