Product Change Notice
All customers purchasing UBBL02, UBBL10, and UBBL13.
Recently, we at Ultralife have completely upgraded our entire line of UBI-2590 batteries. As a customer familiar with our 2590 family of batteries, you will recognize the long-established part numbers UBBL02, UBBL10, UBBL10/B and UBBL13. Today we are proud to announce that effective immediately, these great batteries are being improved as a proactive step towards staying in compliance with new military performance specifications. Designated as the UBI-2590 MGPP lineup (BB-2590/U), these newly improved batteries can be clearly identified by their added part number suffix, “-01.”
