Rechargeable Wearable Conformable Battery

The Ultralife UBBL35 is a 14.4V 7.3Ah rechargeable lithium ion smart battery which has been specially designed to be worn on the human body and can be used to power a range of portable electronic devices whilst remaining concealed.

With a small footprint of 229mm x 203mm and a thickness of <16mm the UBBL35 is curved allowing it to fit around the body. The tough desert tan, semi flexible plastic 'Noryl' casing includes six slots into which mounting straps can be inserted.

The UBBL35 includes Ultralife's SMART CIRCUIT! electronics which provide protection against under-voltage, over-voltage, over-current, short-circuit and over-temperature. In addition an SMBus SBDS compliant fuel gauge provides the host equipment with a myriad of battery performance information which can be relayed to the user. The battery also includes a 5-bar LED display which provides state of charge in 20% increments at the push of a button.

The connector on the UBBL35 is a standard 7 position Glenair connector which mates with Ultralife chargers such as CH0015 and CH0008. Flying leads such as CA0009 and CA0022 are also available.

UBBL35 is the part number for a single battery. The minimum supply multiple is 9 batteries.
