Where do I find a Replacement Battery for my Medical Device

There are many devices in the medical field that have Valve Regulated Lead-Acid (VRLA) batteries installed.

Devices include Ambulatory Infusion Pumps, IV Infusion Pumps, Blood Pressure machine, O2 Saturation, Thermometers, Glucometers, Ventilators, Suction machines, Scales, Portable Telemetry, Feeding Pumps, Defibrillators, Automated External Defibrillators (AEDs), Sequential Compression Devices, Portable EEG/EKG machines, Patient Transfer Lifts, Patient Beds, Ultrasound machines, CDAP/BIPAP machines, and many more.

However, these batteries can vary in technology, voltage and capacity. How do you find the right replacement battery that lasts and is economical?

In this blog, Valen covers off a few points to keep in mind to ensure you make the correct battery replacement choice.

  • Technology
  • Battery voltage
  • Battery capacity
  • Battery charger
  • Battery connectors
  • Battery physical size
  • Budget and time limitations

All of these factors will influence the battery replacement. These details are critical to ensure the correct battery replacement is chosen. 


I want to upgrade my battery to Lithium technology. What do I need to know?

Understandably in today's world, most devices are looking toward Lithium battery power. However, Lithium batteries are built differently to other technologies and will require more specifications in order to design the battery or battery system effectively. 

The following details are required by most Lithium battery designers, in addition to the specifications collected above: 

  • Machine draw
  • Cut-off voltage
  • Maximum space available
  • Connector and charging port
  • Charging method

Most of the specifications will be available in the medical machine's electrical specifications manual.
