New high capacity industrial battery added to yuasa high discharge rate range
Yuasa Battery Sales has added a further battery to its SWL family of industrial valve regulated lead-acid batteries with a new high capacity 12V model, the SWL3800. Ideal for use in uninterruptible power supply and similar high discharge rate applications, the new SWL3800 delivers the same increased performance as other batteries in the SWL family. Typically, this provides up to 40% extra high-rate discharge capacity when compared with standard NPL series batteries.
The SWL3800 features a nominal 10hr rate capacity of 124Ah to 10.8V at 20°C. Standby life expectancy is up to 10 years (design life at 20°C).
The new SWL3800 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 350 x 173 x 272mm high with typical mass of 48kg.
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 1200A for 1s or 600A for 1min and impedance of 4m measured at 1kHz.
