The SWL4250 high capacity 12 V model is ideal for use in uninterruptible power supply (UPS) and similar high discharge rate applications, the SWL4250 delivers the same increased performance as other batteries in the SWL family. Typically, the battery provides up to 40% extra high-rate discharge capacity when compared with standard NPL series batteries.
The SWL4250 features a nominal 10hr rate capacity of 140 Ah to 10.8 V at 20°C with 10-min rate constant power of 4,250 W to 9.6 V at 20°C. Standby life expectancy is up to 10 years (design life at 20°C) and EUROBAT classification is high performance, 10 to 12 years.
The battery features a UL94HB ABS case material as standard with flame retardant (FR) option available for UL94V0 applications. The battery can be installed and operated in any orientation except permanently inverted and complies with IEC61056 and IEC60896-21/22. Case dimensions are 341 x 173 x 281 mm high with typical mass of 49kg.

Operating temperature ranges are -15 to +50°C (charging) and -20 to +60°C (discharging). Optimum storage temperature in fully charged condition is from -20 to +50°C. Additional specifications include low self-discharge characteristics during storage, maximum discharge current of 840 A for 1s or 420 A for 1 minute and impedance of 2.7 mO measured at 1 kHz.

The SWL4250 battery extends Yuasa’s high discharge rate range that includes the SWL3800 12 V model offering a nominal 10hr rate capacity of 124Ah and the SWL2500-6, a 6V battery with 10hr rate capacity of 180 Ah (both to 10. V at 20°C).
