How to Know If Your Car Battery Needs to Be Replaced
Common warning signs of a failing car battery include, but are not limited to the following:
- Unusual Power Fluctuations
- Takes Longer to Start the Engine When You Push the Button or Turn the Key
- More and More Necessity for Jump Starts
- Dimming Headlights
Common Causes of Battery Deterioration
- 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.
- Needing a Jump: If you’ve done something like leave your lights on overnight and require ajump start, this can shorten battery life significantly.
- Vibrations: If your battery’s hold-down clamps are loose, or you drive over rough roads frequently, vibrations will cause internal battery parts to break down faster.
- 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.
To get a better understanding of how long your battery is estimated to last and how often to replace your Toyota car battery, you should consult your maintenance schedule or owner’s manual.
How to Test a Car Battery
You should have your car battery tested during routine maintenance at our Louisville-area service center twice a year. However, if you want to test it between that time, many retailers offer free tests, or you can conduct a DIY battery test from your New Albany home with two simple methods.
Using a Digital Multimeter:
- Set the voltmeter to 20 DC volts.
- Under the hood, touch the negative terminal (black) with the negative meter probe (also black).
- Touch the positive terminal (red) with the positive meter probe (also red)
- Have a friend turn on the headlights and check the voltmeter reading.
- 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 means you have 25% or less charge.
The Headlight Test:
- Turn on the engine, keep the car in park, and make sure the headlights are on.
- Rev the engine and see if the headlight brightness changes.
- 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.
- Take your car to a service center at this point for further assessment.
