About Us

Unipower was founded over 30 years ago, and quickly became one of the most reliable sources of replacement batteries and UPS products for hospitals, clinics, and any other organization that relies on medical devices. The company was founded on the belief that companies should have an alternative to expensive OEM medical device batteries. Over the decades, they have built one of the most comprehensive replacement battery product libraries in the medical device industry with some of the most recognized names, including Duracell, Panasonic, CSB, Sanyo/FDK, Enersys, MK/East Penn, and PowerSonic.


Our commitment to quality is guaranteed – this means you cannot purchase a better-produced battery product anywhere in the industry. Unipower quality control standards include:

  • Eleven Point Data Retention
  • Visual Inspection
  • Pre-Shipment Testing and Comparison to Nominal
  • Random Load and Cycle Testing

A testament to Unipower’s quality is that numerous medical device manufacturers – including Abbott Nutrition, Cooper Surgical, and SSCOR - have asked us to produce batteries for their equipment.

By providing high quality products, Unipower is able to offer the best warranty in the business. We warrant that all equipment manufactured will be free from defects in material and workmanship for a period of up to sixteen months from date of sale.
