<p>A remnant electricity displaying equipment for accumulator has a transparent display rod and a rod cap connected with each other, where an inner side of the connection part of the transparent display rod and the rod cap is formed with a color development cavity, multiple guide ways are arranged in circumferential direction and extended in height direction, and a fixed bracket is formed through the guide ways integrally connected together and fixed in the color development cavity, multiple color blocks are installed between two adjacent guide ways, where specific gravity of each color block is gradually increased in the circumferential, the color blocks installed between two adjacent guide ways float up or sink with the change of density of electrolyzing solution, so that the remnant electricity can be precisely judged by observing the floating condition of the color blocks. The equipment can precisely display remnant electricity of the lead-acid accumulator.</p> |
