A car battery that seems to randomly die can be one of the most annoying things to deal with, and the problem with pinpointing and fixing whatever the issue might be is that sometimes it’s the battery, sometimes it’s the alternator, and sometimes the car’s wiring that’s at fault.
Even experienced mechanics can be baffled when troubleshooting a randomly dying battery. That being said, if you have a misbehaving battery, there are a few things to know. First, don’t be scared by the big black box in the engine bay. It’s just a battery just like any other battery, one with a positive terminal, a negative terminal and electrons flow through wires between both terminals. Even more, its only 12 volts so it won’t shock you.
The primary function of a car battery is to start and run the engine by powering the starter motor and providing electricity for key components, while its secondary function is to electrically power the lights, horn, heater and all the other electronic gadgets in the car. The average life of most batteries stand at around 3 to 4 years, but this can be dramatically shortened depending on how you treat your car. Here are the reason why your car battery is always dying.
Faulty Charging System
The main job of your car’s alternator is to keep the battery charged. If the charge it provides is too high or too low, there will be a problem. Technically, it is said that a fully charged battery produces 12.6VDC voltage and the alternator needs to pump out 13.4V-14.7VDC to properly reach that full charge.
If the alternator isn’t working and isn’t putting out the required 13.4V-14.7VDC, it may be failing to charge your car’s battery correctly. A loose connection, a bad circuit, or just a faulty alternator could be the main culprits and are issues that can be easily diagnosed by a qualified car mechanic.
Driving your car often on short trips can contribute to a short battery life and a battery failing to keep a charge. That’s because the most taxing use of the battery in your vehicle is the initial engine start and short trips simply don’t give it enough time to fully charge.
Extreme cold or heat can stress the internal chemistry, increasing the risk of premature failure. There isn’t much you can do about the impact of temperature extremes In most cases, but it’s a factor that you should be aware of. This build-up leads to shortening of the battery life and lengthen the amount of time needed to charge it.
Excessive Current Draw
There are devices in your car that draw a small amount of current to stay on, such as the clock. Normally, this sort of thing won’t kill your battery; however, if you have an excessive current draw due to a short circuit or a fault of some sort, your battery may die prematurely. Of course, as many know, leaving the interior light on could leave you with a car that doesn’t startup in the morning.
Losing a battery once a year for three years is an indication that something is wrong, and the same goes for a battery randomly dying. If you’re experiencing too much of battery problems, consult a professional mechanic to find out what the problem might be. [Car Battery Prices in Kenya. Car Battery Problems Kenya.]
