Why is Your Porsche Car Battery Not Holding A Charge?

A car battery is one of the most important equipment in a car that assists it in powering on. Without it, almost all other components cannot be able to work. The loud grinding/whirring sound when trying to start a car however is one sound that drivers dread. One of the main and common reasons is because of low battery. The mechanic will obviously tell you it is because of several reasons. Although some of the issues that may have led to the battery being low is because of situations that can be controlled by the user. Listed below are some of the primal reasons that may cause your Porsche car battery not to hold charge.

Human Mistake Factor

Man is to error as the famous adage goes. In that it is normally common to come home from work tired and without knowing, left the headlights on or maybe you forgot to close the door or trunk properly. By morning when you enter the car and try to start it, it just grinds and clicks. Some cars beep either when the lights are still on or the car keys have been removed from the ignition or when a door or trunk is half closed. Others turn any light left on the moment the car is switched off. Such small innovations have helped Porsche from having their batteries drained overnight due to the common human error mentioned above.

Failed/Bad Battery

Some batteries fail simply because their life span have expired. In that its capability to hold charge is no more. A normal standard Porsche battery should be replaced every 3 to 4 years. Every once in a while the car battery ought to be checked whether it holds charge. This can be done by using a multimeter/voltmeter.

Malfunctioning Alternator

In order for a car battery to charge, the alternator needs to be working well. A faulty alternator can be detected when a car headlights start to dim or the charging system warning light shows up on the dashboard. With the engine running, one can connect a multimeter to the car battery and see whether the reading will be between 14 and 15 volts. Anything less will mean the alternator is defective.

Aftermarket Devices

Some of the devices fitted in cars nowadays such as car radio amplifiers, Bluetooth kits or GPS tracking systems tend to drain the car battery as much as a car is turned off. Some of the devices have a permanent live wire connected so that they can retain some settings e.g radio frequency or time. Such devices need to have a manual shut down switch so as to avoid unnecessary battery drainage.

Faulty Fan Belts

Sometimes a mechanic might misdiagnose an alternator or battery for having issues while unknowingly the issue is the fan belt. The fan belt might be slipping hence the alternator ends up making fewer revolutions. This in turns means that the battery won’t be charged sufficiently.  Fan belts ought to be checked or replaced when the car’s service time is due.

Loose/Corroded Battery Terminal

Normally due to overcharge or undercharge, battery terminals tend to form corrosion on either of the two terminals. Experts have found out that if the corrosion is on the negative terminal then that shows that the battery is undercharging. A corroded terminal will hinder the battery from being charged as well as a loose terminal.  White lithium grease should be applied on the terminals once it is cleaned with either hot water or by pouring a bottle of coke.
