This is why it is helpful to know when your battery is on its way out. Here are four signs that you are almost due for a new car battery, brought to you by the mechanics at Chapel Hill Tire. As the North Carolina heat begins picking up, you might start to notice your battery reacting adversely to these changes.
This evaporation also can cause internal battery corrosion. Newer batteries can manage harsh weather conditions with ease, but a battery near the end of its lifespan will begin to struggle in extreme climates. If you leave your vehicle for an extended trip out of town, it could have a dead battery when you return. Your battery is heavily impacted by your driving patterns. While you might think that driving frequently negatively impacts the health of your battery, the opposite is often true.
Your battery recharges while you drive, which means leaving your vehicle sitting for an extended period of time could deplete its charge. To combat this heat, automakers may mount the battery in an isolated area, install a heat shield over the battery, or relocate the battery outside the engine compartment, often under the back seat or trunk floor.
Vibration causes internal battery parts to break down. To minimize vibration effects, use special hold down hardware to secure the battery in place and prevent it from moving. Missing or loose hold down hardware can significantly shorten battery life. While less common than the aforementioned factors, a malfunctioning charging system will also reduce battery life. Persistent under- or over-charging accelerates battery aging. Some newer cars with absorbent glass mat AGM batteries require careful control of charging rates for maximum battery life, and the automaker may even alter the charging strategy as the battery ages.
Finally, allowing any car battery to go completely dead will take a big chunk out of its lifespan, even if you can recharge and put the dead battery back in service. In older models, dim incandescent headlights, particularly when the car is idling, indicates a weak battery. Not every failing battery reveals itself through obvious symptoms so take precautions to avoid a dead battery situation. Inspect the car battery at every oil change. Make sure the cable connections are clean and tight and the hold down hardware is secure.
Once a battery reaches its third year, have it tested annually. A car battery test identifies the deterioration level so you know when it is time to install a replacement battery. More information available in the Things to know about your car battery article. A professional service tech will come to your location, conduct a free diagnostic test of your car's battery and starting and charging systems, and if needed, install a new battery on the spot.
You must consider the battery type, physical size, terminal configuration, and cold cranking amps CCA or amp-hour Ah rating to ensure you get a car battery that properly fits and functions for your make and model vehicle.
Installing an incorrect battery can adversely affect the car's electrical system and cause major damage if the terminal locations create a short circuit with nearby components.
If you are not sure which car battery to buy, ask your auto repair professional or consult your owner's manual. Batteries are either conventional lead-acid or the more advanced AGM design previously mentioned. Most cars on the road today use conventional batteries and some models use AGM batteries.
These batteries are highly spill resistant and better able to handle repeated discharging and recharging, as occurs in cars that have engine stop-start systems to improve fuel economy. Auto manufacturers optimize car-charging systems for the battery type so AAA recommends that your replacement battery always be the same type as the original factory-installed battery. The group number, for example Group 24, is an industry standard that defines the battery's physical size, its hold down configuration, and the type of terminals and their location.
Starting the ignition sends a signal to the battery that kicks off a chemical reaction inside the little black box. The reaction turns into electrical energy that gets the starter motor running and the engine cranking. For most Manitobans who are driving in winter conditions for half the year, that life span may be slightly shorter.
At the three year mark, start paying attention to how your vehicle is running. Get your mechanic to check your battery next time your vehicle is in for regular maintenance. Pay attention to the way your vehicle reacts when it starts as well. Here are seven telltale signs that your car battery is dying:. Over time, the components inside your battery will wear out and become less effective. A slow start is usually the last gasp before a battery kicks the bucket. The battery powers all of the electronics in your vehicle, from your lights to your radio to your dashboard computer.
If the battery is losing its charge it will have a harder time running these things at full power. The more things you plug into your car while driving — like your phone charger — the faster your battery will die. In most vehicles, the check engine light can mean just about anything and it may come on when your battery is running out of juice.
