It's generally a good practice to disconnect the battery when changing a relay or fuse, especially if you're working with components related to the vehicle's electrical system. This helps prevent any accidental short circuits or electrical shocks. However, for most fuse replacements, it may not be strictly necessary, as fuses are designed to be changed without disconnecting the battery. Always refer to your vehicle's manual for specific guidance.
The battery is only a storage device. The alternator replaces the electrical energy that the battery uses every time you start the engine and every time you turn on an electrical device in the car. If the alternator isn't working or isn't working properly, the battery will eventually discharge. Answer if the alternator is in fact working but you have let the battery run empty, simply getting a jump start might not allow the battery to charge sufficiently once you start driving again. you have to charge the battery up a sufficient amount or the battery will just run out again.
