The ULTRALIFE UB0023 (Saft BA-5390A/U) is a primary (non rechargeable) Lithium Manganese Dioxide battery used in a wide range of military applications.

The ULTRALIFE UB0023 (BA-5390A/U) utilizes a solid cathode which results in a safer battery with two separate battery sections which can be connected in either series or parallel. 

When in '30V series mode' the battery voltage ranges from 33.0V to 20.0V and has a capacity of 11.1Ah. In '15V parallel mode' the battery voltage ranges from 16.5V to 10.0V and has a capacity of 22.2Ah.

The UB0023 (BA-5390A/U) features a push-button operated 5 segment LED display which displays the remaining battery capacity in 20% increments - allowing the user to quickly judge if the battery contains enough energy for the task ahead.

The UB0023 (BA-5390A/U) has an operating range of -30DegC to +72DegC making it ideal for the most difficult environmental conditions.
