Powerful performance for demanding areas of use

The YUASA SWL1850 is part of the well-established SWL range of valve-regulated lead-acid batteries (VRLA) and provides outstanding performance for short-term high-current applications. With a 10-minute constant power discharge rate of 1850 watts to 9.6 V, it is ideal for UPS systems, safety lighting, telecommunications systems and other critical applications. Its maximum discharge current of 800 A (1 second) gives additional power reserves during sudden peak loads.

Efficient energy and long service life

With its EUROBAT "High Performance" classification, the SWL1850 achieves a service life of up to 12 years at 20 °C. The low self-discharge of around 3 % per month ensures that the battery remains ready for operation even after extended periods of inactivity. The housing is made of robust ABS plastic and is optionally available in a flame-retardant version (UL94:V0) to meet additional safety requirements.

Technology for versatile applications

The SWL1850 can be installed in almost any position except permanently upside down. The battery is equipped with M6 female threaded connectors that ensure a secure and stable connection. The recommended charging current for cyclic operation is max. 16.5 A, while no limit is needed for float charging. Low-pressure relief valves reliably regulate the gas pressure within the cells, ensuring safe and low-maintenance operation.

The battery meets numerous international standards and certifications, including ISO 9001, ISO 14001, OHSAS 18001 as well as IEC61056 and IEC60896-21/22 standards.
