Daily maintenance and maintenance of maintenance-free batteries

Batteries are mainly divided into three types: ordinary batteries, dry-charge batteries and maintenance-free batteries. Among them, the batteries used in passenger cars that we all are more familiar with are basically ordinary batteries and maintenance-free batteries.   Most of the models currently on the market use maintenance-free batteries, and the most important feature is 'maintenance-free' as the name suggests. Compared with ordinary batteries, its electrolyte consumption is very small, and there is basically no need to supplement distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. Maintenance-free batteries, in order to avoid daily maintenance and maintenance, the design of the exhaust system is significantly different from that of ordinary batteries, so theoretically, it is not necessary to add distilled water or electrolyte frequently. The most obvious feature of ordinary batteries is that they have 6 on the top. A plastic sealing cap that can be unscrewed, with vent holes on it. These sealing caps are used for filling, checking electrolyte and exhaust gas. In theory, ordinary batteries need to check the height of the electrolyte during each maintenance, and if there is a shortage, add distilled water. But with the upgrading of battery manufacturing technology, the maintenance of ordinary batteries is no longer complicated.   Maintenance-free batteries, in order to avoid daily maintenance and maintenance, the exhaust system design is significantly different from ordinary batteries, so theoretically, it is not necessary to add distilled water or electrolyte frequently.
