Loose connections or rusty tensioners can also lead to an inefficient charging system. This indicates that your automobile battery is not charging as it should be, as evidenced by the fact that its output is less than the anticipated 13.5 to 14.5 volts. Imagine a battery that is already undercharged powering the auxiliary automobile parts that must continue to operate even while the vehicle is not in use. Your battery will ultimately get depleted and dead, right?
The car's electrical systems, including the radio, lights, ignition, etc., are powered by the alternator, which also recharges the battery. Even with the engine off, a damaged or malfunctioning alternator diode will improperly keep the circuit charged. Your car's battery will then be drained as a result.
Finding and Resolving a Parasitic Battery Drain
It may be annoying to have a battery that won't retain a charge, and it can be challenging to identify the root of the issue. You will require the aid of a skilled mechanic who can analyze your car's electrical issues and establish whether it is a dead battery or something else in the electrical system, assuming that human error is not the source of the battery depletion.
