It’s the heart of your car and one problem relating to it can prevent you from going anywhere.
It’s your car’s battery.
As with any human organ, this is a part you can’t simply leave until it stops functioning.
Checking it and maintaining it will ensure it lasts you as long as possible and the rest of your engine won’t be damaged by its malfunctioning.
Maintenance can even prolong its life cycle.
But what if you notice a problem? If your car battery voltage is too high you need to tend to it directly. And we will show you how.
Is high voltage a big problem?
Why is this an important part of your vehicle maintenance? Is too much power in a car really a bad thing? It is if you want your car to last long.
The reason the power is regulated is that too much of it will cause risks:
- Voltage will become dangerously high
- The battery can overcharge which will leave it useless
- Engine components that aren’t designed to handle the pressure, temperature or power will be damaged
- The alternator isn’t designed to handle excessive power and eventually it will burn out
This can happen without you knowing. Your first clue may be when your car cuts out or doesn’t want to start anymore. This is why regular maintenance is essential.
General Guidelines – What To Check For
How do you know if your battery is giving problems?
These days maintenance is fast and easy. You don’t even have to visit a professional mechanic. An ordinary volt meter or power probe can be used to test your battery. Simply make sure the battery wasn’t charged recently so you get accurate readings.
12V batteries. Your reading should be anything between 10V and 12.9V. An ideal reading is between 12.4V and 12.7V. Some experts say a reading above 12.6V is better. As soon as your engine is switched on it should increase to 13.7—14.7V.
If it reads below 10V, your battery is going to die very soon. When it rises above 12.9V—while your car isn’t switched on—you have a problem. This can turn into a hazard for you or your car, so you need to find the problem and repair it.
No, it’s not necessarily your battery. Many engine parts connect to the battery and the source of the problem can be there.
Reasons why voltage peaks
A simple problem of loose wires and connections can cause your battery voltage to fluctuate. You may think it is flat, charge it and afterwards voltage can go as high as 15V or 16V.
Here are a few connections to check:
If you have tools and skills, you can repair these yourself or ask a professional to play it safe
Inside your alternator is a voltage regulator. This part manages your battery’s voltage. If it malfunctions you experience fluctuating voltage readings.
Luckily you don’t have to replace either the battery or the entire alternator. Alternators can be repaired. There is a quick solution and most professionals can repair the unit while you wait.
