How Often to Replace a Car Battery

It’s recommended you should replace your car battery every 4-5 years. This depends on several factors, though, so you’ll want to learn more about car batteries with our service team at Big Star Buick GMC near Houston. With our helpful guide, you can learn how often to replace a car battery and where to find a high quality battery!

How to Know If Your Car Battery Needs to Be Replaced

Wondering how to know if your battery is reaching its end? Here are some warning signs for Channelview drivers to watch out for:

• Dimming headlights
• More frequent need for engine revving or jump starts
• Takes longer to start the engine when you turn the key/push the button
• Unusual power fluctuations

What Causes Car Battery Deterioration?

• Heat: Hot weather causes the evaporation of liquids inside a car battery, so if you live in a more consistently hot climate, your battery life will be inevitably shorter.
• Vibrations: If your battery’s hold-down clamps are loose, or you frequently drive over rough roads in Crosby, vibrations will cause internal battery parts to break down faster.
• Needing a Jump: If you’ve done something like left your lights on overnight or let your engine idle for too long and require a jump start, this can shorten battery life significantly.
• Time: A car battery can only go through so many charge cycles, so the death of your car battery is unavoidable — but proper care can prevent the battery from dying on you early.

For a more solid answer for how long your car battery should last with proper care, check your owner’s manual as well as your vehicle’s regular maintenance schedule.

How to Test a Car Battery

If you’re not comfortable with testing your car battery at home, you can always schedule a service appointment with our team. If you’re looking for instructions on how to test a car battery at home, follow these easy methods:

The Headlight Test: 

1. Turn on the engine, keep the car in park, and make sure the headlights are on.
2. Rev the engine and see if the headlight brightness changes.
3. If the headlights get brighter, that means the current is not strong enough to keep the lights at normal brightness while the car is idling.
4. At this point, we recommend taking your car to a service center for further assessment.

Using a Digital Multimeter:

1. Set the voltmeter to 20 DC volts.
2. Under the hood, touch the negative terminal (black) to the negative meter probe (also black).
3. Touch the positive terminal (red) to the positive meter probe (also red).
4. Have a friend turn on the headlights and check the voltmeter reading.
5. At 80℉, 12.5 volts or higher means your battery is fully charged. 12.3 volts means it’s at about 75% charged.11.8 volts or lower indicates a charge level of 25% or less.

How Much is a Replacement Car Battery?

The car battery cost can range from $75 to $120 depending on the type you need. If you need a premium battery, it could cost up to $200. And if you have a hybrid car, you’ll need to keep in mind that hybrid car batteries are even more expensive and can cost between $1,000 and $6,000.
