Use printed screens. After the battery is finished, a label is usually attached to its surface for identification purposes. However, after long-term use, the label will be affected by the environment and fall off, making its specifications unrecognizable. Printable screen frames can be used for printing during renovation. Before the battery is packaged, it is necessary to print a logo on the surface of the battery. The corresponding logo includes trademark, brand name, product model or specification information, etc. When printing logos with different contents, different printing frames need to be replaced.
