Your Nissan battery light might be on for various reasons, and its best to consult your owners manual and a Nissan dealer to ensure you can get to the root of the problem. Try and make it home, or better yet, to your local Nissan dealership to have a new battery installed. This wont fix your battery issue, but it might buy you some power and time, and increase the distance you can drive before the battery completely dies. If the battery light does come on, try turning off non-essential accessories. In that case, the number of electrical accessories you use can quickly drain the battery and cause the battery light to illuminate. However, suppose there are alternator and battery issues such as a bad belt or a dying battery. If your battery is fully charged and your alternator is working as it should, the number of accessories you use when driving shouldn't cause the battery light to come on. Think of all the things that require power while driving - air conditioning, radio, headlights, power steering, and GPS to name just a few. Then, grab a wrench or pliers and tighten the nut on each terminal until it fits snuggly.

To fix this, ensure the battery cable terminal is as far down on the battery post as possible.

When there isn't good contact between the cables and the battery terminals, your Nissans battery light may come on. The battery cables should fit tightly around the battery terminals to have a good connection. Luckily, cleaning your battery terminals is simple! Put on gloves, disconnect the battery cables by following instructions in your owners manual, and use a toothbrush and a mixture of one tablespoon of baking soda mixed with one water cup to clean the battery posts and terminals. Corrosion could be blocking the flow of electricity, which means the alternator cant do its job and the battery light will stay on. If you get under the hood and see a white-ish, crusty, or powdery substance where the battery cables meet at the posts, its a good sign that there's corrosion. The only solution is to replace the alternator belt. As a result, your alternator cant properly function, and the battery wont receive the energy it needs. However, the alternator belt can crack, come loose, or break with age. The alternator belt helps receive and distribute power from the alternator. If the alternator is exhausted, you'll have to replace it. If the alternator completely dies, the power that is left in the battery will only last you a few more minutes. Once the alternator starts to go, it cant keep the battery charged, which could trigger the battery light. Alternators generally last between five and seven years or about 100,000-150,000 miles. The alternator keeps the battery fully charged when you're driving, and the belt connects the alternator, engine, and accessories. Don't have a multimeter and don't feel like buying one? Stop by a participating Nissan dealer near you for a complimentary battery inspection.* Bad Alternator and Alternator Belt If the reading is lower than 12.2 volts, the battery most likely needs to be replaced. A good voltage reading is between 12.4 and 12.7 volts. You can determine if a dying battery is the cause by testing the voltage with a multimeter. However, other factors can cause the battery light to illuminate, too. A dying battery will typically trigger the battery light on your dashboard. This is especially common if you live in a warm climate, as batteries fade faster in hotter temperatures. The average 12-volt Nissan car battery has a lifespan of between three and five years, so the battery light on your Nissan might indicate that you simply have a weak or old battery. And before you start to tinker, remember to first disconnect the battery cables. Consider wearing rubber gloves and goggles if you're going to lift the hood and investigate a battery issue. Remember that caution always comes first if you're attempting to troubleshoot the problem yourself. However, if it doesn't go away, a few different things may be going on. When that battery light comes on when starting your car, don't panic! Its entirely normal for this to happen when you first start your Nissan, and it should turn off after a few seconds. If the battery completely dies or fails to recharge, your car will be unable to function - and the battery light on your Nissan will come on.

The battery provides energy to virtually every electrical component of your Nissan - from the ignition and engine control units to the headlights, radio, and interior lights. Standard vehicles generally have a 12-volt battery with six cells, each with 2.1 volts when fully charged.
