Your car’s battery powers the electrical system, which includes everything from the dashboard lights and wipers to the headlights and radios. Unfortunately, it runs out of juice after some time and might even render your vehicle undrivable.
How Many Amp Hours Are In a Car Battery?
The amp hours (Ah) of a car battery can range anywhere between 40 and 75 Ah, depending on the vehicle’s size and other specifications. Regular sedans usually have 40 Ah on their batteries, while SUVs and larger vehicles like trucks can have 50-75 Ah on theirs.
What Do Amp Hours Mean?
Amp hours refer to the length of time a battery can last. For example, if a battery has a rating of 100Ah, that means it can produce 100 amps for one hour, 50 amps for two hours, 25 amps for four hours, and so on.
What Can Drain Your Car’s Battery?
Car batteries are manufactured to last for a specific period before it needs replacement. However, the battery can drain a lot faster than normal because of some practices or issues. Here are some of the things that can make your car’s battery die out faster.
Leaving the Lights On
Leaving any light on, such as the headlights, dashboard lights, and even the small map light, can drain your car’s battery. It’s why some newer vehicles come with advanced features that automatically turn these lights off after a certain period of time.
Loose or Corroded Battery Connections
Loose or corroded connections can drain the car battery because the terminals can’t transmit power properly. In some cases, the loose connections can even cause the vehicle to stall.
Alternator Issues
The alternator is responsible for charging the battery while you’re driving. If it’s broken, you might have trouble starting your car or notice signs of decreased performance while you’re out on the road.
Frequently Going On Short Drives
It takes a ton of power to get the engine running, and turning the vehicle on and off at every pit stop might prevent the alternator from charging the battery properly.
Weather Conditions
The lifespan and performance of your car’s battery can also depend on the weather一especially if you have an old one. New batteries can withstand extreme seasonal temperatures, but old ones tend to die out faster than normal when the weather is too hot or cold.
