Telltale signs of a dead battery are an engine that is slow to turnover and dimming lights on the dashboard. Vehicles today provide indicators that the battery might be failing with a check engine or battery warning light on the dashboard. If a problem is suspected with the battery, a visual inspection under the hood can help confirm whether the battery is the issue. Look for signs like a swollen battery case or corrosion on the terminals. Both could be a sign that it is time for a battery replacement.
Common causes of battery failure include leaving headlights, interior lights, flashers, electronic chargers and the radio on while the vehicle isn't running. Not starting a car for a long period of time, particularly in cold weather, is another common issue. Experts say vehicle batteries lose 33 percent of their charge when the temperature dips below freezing and more than 50 percent of the charge when the temperature falls below zero. Poor battery maintenance and the battery age can also reduce battery charging ability.
Recharging vehicle batteries is commonly referred to as "jump starting." First, you’ll need another vehicle with a functioning battery.
Regular maintenance helps extend battery life. Ask a trusted car care partner to conduct a safety check with every oil change. Battery safety inspections include checking terminals for corrosion and cleaning them if needed. If your vehicle will not be used for an extended period of time, it’s wise to invest in a battery charger so you’re prepared if and when you need a charge.
