Summer battery test is necessary

Nowadays, many batteries are maintenance-free. Of course, the owner does not need to check his battery liquid. It is completely enclosed. Do not disassemble or add distilled water.

However, more batteries still need to be maintained by the owner himself. In fact, it is mainly to check whether the battery liquid is enough, otherwise it will affect its performance, and even cause the battery to end its life in advance, which is a pity. When checking the battery fluid, just check if it is between two horizontal lines. As in this case, it is suitable and no other work is required. If the liquid level is lower than the bottom line, you need to add the battery liquid, you can add it to the repair shop or 4S shop, or you can add it yourself by purchasing it at the decoration store or auto parts store. If you find that the battery liquid is dry quickly, but you can't find the battery liquid of distilled water at a time, you can buy a bottle of referenced pure water to serve as a battery liquid to save the emergency.
