Brand Image for BB-2590/U



The BB-2590/U (Ultralife part number UBBL02-01) is a rechargeable Lithium ion version of the primary BA-5390A/U battery and is designed to meet U.S. Army MIL-PRF-32383/3.

The UBBL02-01 contains two independent battery sections which can be connected in either series or parallel.

In 30V 'series mode' the battery operates between 33.6V and 20.0V (28.8V average) and delivers 8.7Ah. In 15V 'parallel mode' the battery operates between 16.8V and 10.0V (14.4V average) and delivers 17.4Ah.

The UBBL02-01 features dual LCD displays which indicate the absolute state of charge for each section.

The UBBL02-01 is used in a wide range of military applications including robotics, AUVs, UUVs and military communications such as the AN/PRC-117G, AN/PRC-117F, AN/PRC119 and AN/PSC-5D.

The Ultralife UBBL02-01 is an improved equivalent of the Bren-Tronics BT-70791A (6.8Ah) (upgraded to BT-70791CK) and BT-70791BK (7.5Ah).
