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

DURACELL® 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

(70°F), an alkaline battery retains approximately 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.

ULTRALIFE® 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.
