Battery Compatibility
Recommended Batteries
Nine-volt alkaline or lithium batteries are
recommended for use in the CADD-Prizm
®
pump. Carbon-zinc, mercury, nickel-cadmium,
or zinc-air 9-volt batteries should not be used.
Battery Life
The CADD-Prizm
®
pump has been designed to
provide optimal battery life. The expected
battery life in the CADD-Prizm
®
pump depends
on the following factors:
• Programmed delivery rate
• Operating temperatures
• Frequency of display backlighting
• Frequency of printing
• Battery type and brand
• Battery age

Alkaline Battery Life
The following tables may be used to predict
typical alkaline battery life at different delivery
rates when an alkaline battery is used in the
CADD-Prizm
®
pump. As expected, battery life
decreases as the delivery rate increases. These
tables are based on laboratory tests using fresh
DURACELL
®
alkaline batteries in CADD-Prizm
®
pumps while the pumps were operating at room
temperature.
Actual battery life may be significantly shorter
depending on the operating temperature and
the storage conditions of the battery.
Battery life is shortened significantly at very
low operating temperatures. For example, at
0°C (32°F), an alkaline battery will yield
approximately 30% of its normal capacity.
Alkaline batteries do not need to be stored in a
refrigerator. After four years of storage at 21°C
3 Batteries
(70°F), an alkaline battery retains approxi-
mately 86% of its original capacity. Battery life
will be shorter if the battery is stored above
room temperature. An alkaline battery stored at
43°C (110°F) will be down to approximately
80% of its capacity within one year.
Recommended storage conditions are 10°C to
25°C (50°F to 77°F) with no more than 65%
relative humidity noncondensing.
The following tables are based on laboratory
tests conducted at room temperature using fresh
DURACELL
®
alkaline batteries and a CADD
®
administration set. Actual battery life will vary
depending on the brand of battery, battery shelf
life and temperature conditions.

Lithium Battery Life
The following tables may be used to predict
typical lithium battery life at different delivery
rates when a lithium battery is used in the
CADD-Prizm
®
pump. As expected, battery life
decreases as the delivery rate increases. These
tables are based on laboratory tests using fresh
ULTRALIFE
®
lithium batteries in CADD-Prizm
®
pumps while the pumps were operating at room
temperature.
Actual battery life may be significantly shorter
depending on the operating temperature and
the storage conditions of the battery. Lithium
battery life is dependent upon the temperature
and relative humidity of storage. Recommended
storage conditions are less than 20°C (68°F)
with a desiccant to ensure less than 10%
relative humidity.
The following tables are based on laboratory
tests conducted at room temperature using fresh
ULTRALIFE
®
lithium batteries and a CADD
®
administration set. Actual battery life depends
upon the brand of battery selected, the
particular battery selected, battery shelf life,
and temperature conditions. Deltec’s testing
indicates a large variability in battery life.
