The [URB12450-U1-SMB battery](https://ultralifecorporation.com/ECommerce/product/urb12450-u1-smb/lfp-smart-u1), which features accurate fuel gauging and integrated safety circuitry, is designed to replace and improve on traditional sealed lead acid (SLA) batteries in applications such as medical carts, robotics & uninterrupted power supply (UPS) systems.** SLA batteries are often used when bulk energy is required for stand-by applications, but this mature technology performs poorly when required to work under a cyclic regime or when the temperature is elevated. SLA batteries have poor volumetric and gravimetric energy density which is pushing against the tide of modern devices which need to be made smaller and lighter. It is for this reason that ULTRALIFE has introduced the [URB12450-U1-SMB](https://ultralifecorporation.com/ECommerce/product/urb12450-u1-smb/lfp-smart-u1) – a compact Lithium Iron phosphate battery which can be cycled \>2000 times, deliver rated capacity at high currents and can be charged using a regular SLA charger.  In addition the [URB12450-U1-SMB](https://ultralifecorporation.com/ECommerce/product/urb12450-u1-smb/lfp-smart-u1) features Ultralife’s proprietary Smart Circuit technology that combines an industry standard communication interface with Ultralife’s advanced battery monitoring parameters, allowing host devices to read pertinent status and accurate runtime predictions directly from the battery. The [URB12450-U1-SMB](https://ultralifecorporation.com/ECommerce/product/urb12450-u1-smb/lfp-smart-u1) smart battery is assembled in the Ultralife NY plant so customers can be assured of exceptional quality and fast delivery times.  It joins a range of SLA replacement batteries offered by Ultralife Corporation, which are available across Europe through UK-based Ultralife company [Accutronics](http://www.accutronics.co.uk) and numerous distributors.
