Where is the car battery switch located?

[DelMiguel]

Currently, most car batteries in use are maintenance-free batteries, which do not have a switch cover and cannot be opened as they are sealed. Below is more information about maintenance-free batteries: 1. Maintenance-free batteries are made with lead-calcium alloy grids, designed with the latest fully sealed structure and modern production processes from the 1990s. 2. These batteries decompose less water during charging, have lower water evaporation, and release fewer sulfuric acid gases. They do not require adding any liquid electrolyte, have a longer storage time, and compared to traditional batteries, they offer superior qualities such as high performance, maintenance-free operation, safety, reliability, and a long service life. 3. The lifespan of maintenance-free batteries is twice that of ordinary batteries. They continuously convert electrical energy and chemical energy during the charging and discharging processes to provide power for the car, belonging to the category of secondary batteries.
