How Often to Replace a Car Battery

Auto Mechanic Replacing Car Battery

If you drive every day in Roseville, knowing how often to replace a car battery will help you to avoid battery issues on the road. In the guide below from the Sacramento Chrysler Dodge Jeep Ram service department, learn how to know if your car battery needs to be replaced and how to test a car battery at home in Folsom.


How to Know if Your Car Battery Needs to Be Replaced

From the weather to your driving habits in Elk Grove, the factors affecting how often to replace your car battery may vary. Numerous jump-starts, excessive vibration from loose battery hold-down clamps, and hot temperatures can all shorten battery life. Plus, your battery can only take so many recharge cycles and will wear down over time. Here’s how to know if you car battery needs to be replaced:

  • Your headlights are dim.
  • The engine is slow to start.
  • The battery dies and needs a jump-start more often.
  • You notice unusual power fluctuations in your car’s electrical system.

How to Test a Car Battery

Battery checks are part of your vehicle’s regul;ar maintenance schedule, but it’s helpful to know how to test a car battery at home in Rocklin. If you notice any signs that you car battery could be losing power, try either of these methods to test it out:

The Headlight Test

  1. Start the engine and put the car in park.
  2. Turn on the headlights.
  3. Rev the engine and watch for the headlights to get brighter. If they do, the battery’s current is too weak to keep them at normal brightness levels while the car idles.
  4. Schedule service for a battery replacement if necessary.

The Digital Multimeter Test

  1. Set your voltmeter to 20 DC volts.
  2. Open the hood and touch the negative meter probe (black) to the negative battery terminal (also black).
  3. Next, touch the positive terminal (red) to the positive meter probe (also red).
  4. Ask a friend to turn on the headlights.
  5. Check the voltmeter: at a temperature of 80℉, a reading of 12.5 volts or higher indicates a fully-charged battery. A reading of 12.3 volts indicates charge levels of about 75%. If your voltmeter reads 11.8 volts or less, the battery charge is at 25% or less and it’s time to schedule service.

How Much is a Replacement Car Battery?

If it’s time for a new battery, how much is a replacement car battery going to cost? That depends on the kind of battery your car needs. Generally, a new car battery will cost you between $50 and $120. High-end batteries may cost between $90 to $200, and hybrid batteries as much as $1000 to $6000. Keep in mind that the higher cost of a hybrid battery is partly offset by lower fuel costs.
