Development of a new design of valve-regulated lead-acid battery (new Model YT4B) for motorcycle use

In response to the demand for a smaller and lighter valve-regulated lead-ac id (VRLA) battery for motorcycle use, and which retains the performance of the present model, Yuasa has developed a new YT4B model battery. Although t his battery is lighter, it possesses similar or even better performance tha n the two present version in terms of high current drain, capacity retentio n during standing at high temperature, and recovery by charging after overd ischarging. The new battery uses thinner plates, made possible with an expa nded grid for better performance. It also features a wet (electrolyte-fille d) and charged design for easy handling when installing, and has the same l evel of safety as the standard YT4B technology. (C) 2000 Elsevier Science S .A.
