There are a few ways to check your cars battery health. If you have a voltmeter handy, you can check the voltage of your battery. You can do the headlight test, which consists of turning your car and headlights on to check the brightness, if they are looking dim it might be time for a new battery. Lastly, you can conduct a physical check. Some modern day batteries have built in health indicators, if yours does not you can tell a lot about your battery health by checking for a sulfuric smell or any dried/bubbling liquid which can indicate a battery acid leak. If you have any of these issues, feel free to bring it to our service center for a replacement!
