Voltage (V): Match the battery voltage to your infusion pump’s requirements. Common voltages for infusion pumps include 12V and 24V.

Capacity (mAh): Higher capacity provides longer operating time between charges.

Discharge Rate: The battery should be able to provide sufficient current to power the infusion pump’s motors and electronics.

Chemistry: Li-ion batteries are often preferred for their high energy density, lightweight design, and long lifespan.

Cycle Life: Choose a battery with a long cycle life to reduce the need for frequent replacements.

Pump Model and Compatibility: Different infusion pump models have specific battery voltage and connector requirements. Ensure compatibility with your device.

Drug Delivery Needs and Usage Patterns:  The type of infusion therapy, drug dosage, and frequency of use will influence the required battery capacity (mAh) and runtime.

Portability Needs: Consider the weight and size of the battery pack, especially for ambulatory pumps or those used in home healthcare settings.

Operating Environment: If the pump will be used in varying temperatures or challenging conditions, choose a battery with a suitable operating temperature range.
