A few reasons why protection of batteries with simple fuse link is not OK: aa lammable hydrogen gas is always present during battery recharging. F Hydrogen gas is potentially explosive if allowed to accumulate in a closed area. aa revent open flames, sparks, or electrical arcs in the battery charging area P to minimize the danger of explosion. aa reaking capacity of »fork lift fuse link« is less than 1kA at nominal B voltage!
