Ideal for use in uninterruptible power supply (UPS) and similar high discharge rate applications, the new SWL2500-6 delivers the same increased performance as other batteries in the SWL family. Typically, this provides 40% extra discharge capacity compared with standard NPL series batteries.

The 6V SWL2500-6 features a nominal 10hr rate capacity of 180Ah to 10.8V at 20°C. Standby life expectancy is up to 10 years (design life at 20°C).

The new SWL2500-6 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. The new battery complies with IEC61056 and IEC60896-21/22. Case dimensions are 297 x 168 x 231.5mm high with typical mass of 32.5kg.

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 1500A for 1s or 800A for 1min and impedance of 3mΩ measured at 1kHz.
