Where is the battery fuse located?

The battery does not have a fuse. Here are specific details about the battery: 1. Function of the car battery: When starting the engine, it provides a strong starting current to the starter and works together with the generator to supply power to electrical equipment. When the engine is idling, it powers the electrical devices. The car battery also acts as a capacitor, protecting the vehicle's electrical equipment. 2. Voltage: With the increasing number of electrical devices in vehicles and the emergence of mild hybrids, the 12V voltage is no longer sufficient, leading to a continuous increase in voltage. Currently, the mainstream mild hybrid voltage is 48V.
The battery fuse is usually hidden inside the plastic fuse box in the engine compartment, located near the battery or at the front of the engine. I've driven many cars, like Fords where it's typically under the left side of the hood, while Toyotas might have it under the driver's seat. The exact location should be checked in the user manual, which contains detailed diagrams and instructions. If the fuse is blown, the car may fail to start or lose all power. You can replace it yourself: first open the hood, find the fuse box cover marked with "Fuse", then use needle-nose pliers or a special tool to pull out the bad fuse and insert a new one with the same amperage. Always disconnect the negative battery cable before working to avoid electric shock or short circuits. It's not difficult but safety comes first. Regularly check the electrical system to avoid excessive modifications that could cause fuses to blow.
