Slow Start? Time for a New Car Battery

When temperatures fall below 20 degrees, virtually any vehicle will struggle to start. Once it falls below 0, the struggle becomes even more real. However, if you notice this type of sluggish behavior when starting and the temperature has not dropped, you should get your battery tested as soon as possible. The worst thing you can do is just ignore it and get right on the road because your vehicle could be warning you that it’s time for a new car battery.

Know When to Replace a Car Battery

Check Engine Light

If you notice the check engine light is on in your vehicle, there is a 99 percent chance something is wrong. In most instances, it indicates something is malfunctioning in your engine. It could also be indicating it’s time for a new car battery. However, the only way you can truly know is by having a diagnostic test run on your vehicle at Gloucester Toyota.

Does Your Battery Smell Like Rotten Eggs?

If your battery smells, it is giving you a warning sign it’s about to fail — if it has not already. Under normal circumstances, your battery should have no odor or aroma. However, when find your battery starting to emit rotten egg smells, it could mean it has vented gas and has released sulfuric acid and corrosion that could cause damage to more expensive parts of your engine. While the rotten egg smell and corrosion could mean a new battery today, it could put you at risk and cost you exponentially more if left unattended.

Are Your Car Accessories Not Working?

If your radio or other car accessories do not turn on, you should not mistake it for a minor inconvenience. Whenever you have the ignition in the ‘On’ position, the battery should provide enough voltage to run your headlights, windshield wipers, radio and other electronic devices. However, if these accessories tend to dim or flicker before starting, it’s more than likely time to replace your battery.

Has Your Battery Gained Weight?

When your vehicle’s battery was designed, it was engineered with a very defined footprint. Anytime your battery gains weight or becomes swollen, you should be able to detect it. In the event you notice your battery is swollen, your alternator may have a faulty voltage regulator, which has overcharged your battery. Unfortunately, this problem of overcharging the battery is caused by hydrogen gasses building up faster than the battery can dissipate. This means damage has already been done to your battery, and it’s time to install and remove it.
