URB12400-U1-SMB

Ultralife 12.8V 38.4Ah (492Wh) LiFePO4 Smart Battery

ULTRALIFE’s new URB12400-U1-SMB Lithium Iron Phosphate smart battery offers incredible performance in a wide range of transportable and stationary equipment, including medical carts, delivery robots and UPS systems. The inclusion of Ultralife’s SMART CIRCUIT™ battery management electronics provides the user with accurate runtime information in addition to a balancing and protection system which maximises both safety and performance.

The URB12400-U1-SMB is specifically designed to replace and outperform lead acid batteries in mission critical applications. The tough UL 94V-0 flame retardant polycarbonate case ensures internal cells and electronics are protected at all times and unlike a lead acid battery the URB12400-U1-SMB can be mounted in any direction and does not require charging in a vented area. When used in a cyclic application more than 2000 cycles are possible, making it a truly ‘fit & forget’ proposition for many applications.

The inclusion of Ultralife’s SMART CIRCUIT™ battery management electronics and RJ45 communication port allows host devices to communicate with the battery via SMBus. Important battery information such as Runtime to Empty (minutes), Relative State of Charge (%) and Cycle Count (#) is available making the battery an active part of any host device’s power management system.

The URB12400-U1-SMB is qualified for use with medical cart inverters from Tripp Lite and Ametek Powervar, replacing lead acid batteries or LiFePO4 batteries from Valence Technology, Inventus Power or Power-Sonic.

As safety is paramount, the URB12400-U1-SMB is internally protected against over-charge, over-discharge, over-current and over-temperature while a cell balancing system ensures the internal battery cells operate in unison, promoting a higher degree of safety, longer runtime per cycle and more cycles over life.

The URB12400-U1-SMB can be continuously discharged at currents up to 20A and pulsed at currents up to 100A making it ideal for high power motor driven applications. Regulatory compliance is assured as the URB12400-U1-SMB meets the requirements of ST/SG/AC.10.11 section 38.3 (transportation) and is certified to IEC 62133-2:2017 (safety). This means it can be easily incorporated into medical equipment certified to IEC 60601-1.

OEMs can rest assured that the URB12400-U1-SMB meets the most stringent quality standards as its manufactured in the USA at Ultralife’s NY plant. The facility holds both ISO 9001 and ISO 13485 registration.
