A bnef review LS gven of the tistoo of the research and development of sealed lead/ acid battenes dunng the 30 years smce, m 1959, the Yuasa Battery Co mtroduced a small-sized sealed battery as the power supply for portable televlslon sets In 1965, Yuasa began the full-scale mass production and sale of a small-sized sealed lead/acid battery under the NOYPER brand In 1970, the use of a Pb-Ca alloy gnd was adopted, and there followed the successful development of a sealed battery wnh an oxygen-recombmation faclhty In 1976, kuasa more or less estabhshed the basic technology for the valveregulated sealed lead/acid battery-the NP battery-which IS now the type m general use Throughout the 198Os, Yuasa, has contmued development III order to expand the sphere of apphcatlon for the production technology of valve-regulated battenes for motorcycles, as well as for statronary duties wth large capacmes of 100 to 3000 A h Recently, m order to unprove the rehabtity and boost the output of sealed lead/acid battenes for employment m LJPS power sources, Yuasa has been workmg mtently on the design of a valve-regulated lead/acid battery wth outstandmg charactenstlcs for highrate dscharge and resstance to high temperatures
