The ULTRALIFE BA-5390A/U is a primary (non rechargeable) Lithium Manganese Dioxide battery which is used in a wide range of military applications.
The BA-5390A/U offers approximately 50% more energy than a BA-5590 Lithium Sulphur Dioxide battery. Unlike the BA-5590 (which uses a liquid cathode), the ULTRALIFE BA-5390A/U utilises a solid cathode which results in a safer battery.
The BA-5390A/U has two independent battery sections which can be connected in either series or parallel. 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 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 BA-5390A/U has an operating range of -30DegC to +72DegC making it ideal for harsh environmental conditions.
