How to Test Your Vehicle's Battery
Do you think your vehicle's battery may be dying? It could be if you are having to jump start it regularly or if it is sluggish to start. You will need to check your battery life.
You will need a digital voltmeter and gloves to avoid getting battery acid on you. Make sure your vehicle and all lights are off. Find your battery's positive and negative terminals. Take the positive test lead, usually red, and connect it to the positive terminal on your battery.
