Our family of “2590” batteries was born out of support of Military communications gear, and has evolved into many use areas worldwide.

In compliance with new military performance specifications Ultralife have completely upgraded their entire family of UBI-2590 batteries - UBBL02, UBBL10, UBBL10/B and UBBL13. Now designated as the UBI-2590 MGPP line-up, these newly improved batteries can be clearly identified by their added part number suffix, “-01.”

All designed to meet the new MIL-PRF-32383/3(CR) U.S. Military Performance Specification, the new “-01” versions also come with brand new labelling, complete with military mandated text and symbology.

The Ultralife UBI-2590 batteries are also extremely popular with non-military customers and therefore Ultralife have also released the same improved batteries as commercially labelled versions with an additional suffix, “-CB” for quick international market delivery. These new “-CB” versions have a redesigned, more marketable, label and meet numerous national marking requirements. The “-CB” versions are also registered with various national agencies for regulatory compliance to facilitate importation into US and Canadian medical markets, as well as France, Switzerland, South Korea, Japan and India commercial markets.
