Signs of a Poor Battery



When you own a vehicle, remember to bring it in for regular maintenance inspections. Also be aware if there is anything out of the norm with your vehicle between visits. One part to inspect is the battery. If there is an issue with the battery, it may be due to poor battery terminals. These should be regularly inspected to make sure they are not broken or damaged. Also there should not be any corrosion on them. Corrosion on the terminals is commonly caused by electrolysis from the different metals on the terminals and battery cables. It can also occur when there is an imperfect seal between terminal posts and the plastic casing. This can allow sulfuric acid to build up on the terminal posts.


Dimming headlights on your vehicle may indicate a poor battery. You might notice if the headlights are dimmer than they used to be, especially driving at night. Another sign is if the headlights fade while the vehicle is being started, or just after it has started. If you notice dimmer headlights or if they are dimming as you travel, make sure to bring your vehicle in a soon as possible so we can inspect it over for any issues.


Another way to tell if the battery is dying is to turn the key in the ignition until the electrical accessories turn on. These include the radio or power windows. If the battery is running low, some or all of these accessories will be slow and sluggish. The windows will roll up or down slower than normal. If the accessories do not come on at all, the battery is completely dead and will need to be recharged or replaced. By coming in at the first sign of an issue, you can prevent further damage to the vehicle in the long run.
