What You Need to Know About Car Batteries
What does your car battery do?
The battery of your car stores electricity for two functions – to give the engine a kick start of energy, and when the engine’s not running to supply electricity to the vehicle’s accessories. As car technology developed with many other features like phone charges, heated seats, screens, etc, there is way more demand from the battery.
That’s why manufacturers have developed a range of battery types and technologies, to deliver power over longer periods.
How to take care of your car battery
Three things that you should be careful with the car batteries are heat, vibration, and discharging.
- Heat indicates corrosion and electrolyte evaporation, which can kill the battery.
- Vibration shakes the plates around and can indicate to loosen the internal connection. Fit your battery properly to prevent vibration.
- Discharging is the worst thing for a lead-acid battery. Leaving the lights on, or things plugged in all day can cause the battery to never fully recover.
How long does a battery work
Car batteries typically will last 4-7 years, but this also depends on climate, how you use it, and care. A failing vehicle battery will give you warning signs such as dimmer headlights, compressor noises, strange air conditioning, or slow engine cranking. You should regularly test your car battery, especially before winter.
- Slow engine crank: When you want to start your vehicle the cranking of the vehicle takes longer than normally
- Low battery fluid: The battery of the car probably has a transparent part where you can see the level fluid. If the battery fluid level is below lead plates inside, it’s time to test or replace your battery with a new one.
- Check engine light: This light usually appears when your battery power is weak.
- Old battery: Batteries can last longer than 3 years but a battery that is older than three years is considered old. If your car battery is this old you should test it or replace the battery.
