Customer Questions About Car Batteries

Finding quality automotive batteries can sometimes be overwhelming and confusing. There are many different factors to consider when shopping for high performance batteries including different brands, prices, warranties, performance capabilities, and much more. Because a high performance car battery is often a significant investment, it is important to do your research and get all your questions answered prior to making your final purchase. If you are trying to learn more about a high performance battery selection, we can help you along the way. Here are some answers to frequently asked questions about the standard and performance car battery:

How To Disconnect Car Battery

When disconnecting a car battery, the negative terminal needs to be removed first and then the positive connection. When reattaching the cables, the reverse order needs to be followed with the positive terminal first and then the negative cable. Most cables can be loosened with either a wrench or socket. Sometimes twisting the connection is required to free it from the battery terminal. Be sure to clean the battery terminals and cable connections before reconnecting.

How To Replace Car Battery

To replace the car battery, the engine needs to be turned off with the key out of the ignition. Open the hood and locate the battery. Next, remove any components that might be in the way of the battery such as air intake ducting. Remove the battery cable connections with the negative terminal first and then the positive cable. Then locate the battery hold down hardware, either on top of the battery or down at the base of the battery, and loosen the hardware. With the battery hold downs unbolted, the battery can be carefully lifted out of the vehicle. Next, clean the battery cable connections with a brush and remove the plastic protector caps from the new battery terminals. Install the replacement battery into the vehicle. Tighten the hardware and then reattach the battery cables with the positive connection first followed by the negative terminal. Re-install any components that were removed in order to take the battery out of the vehicle. Finally, double-check that everything is tightened correctly and that all tools are removed from under the hood. The vehicle can then be started with the project complete.

How Long To Charge Car Battery?

There are several factors involved in how long it takes to charge a car battery. The first is how low of charge that battery has. The less charged it is, the more time it will take to fully charge it. Another factor is the type of battery charger being used. Battery chargers can offer different charging amperages. The lower the amps, the longer the charge will take. However, faster charging can reduce battery life. Charging time typically can run anywhere from 2-8 hours depending on the battery and charger.

How To Test Car Battery

The first step in testing a car battery is confirming it has a full charge. Hooking a battery charger up to it will verify it is at full charge as most battery chargers let you know the charging state. If the battery charger continues to charge without success or, for some chargers, indicates the battery is defective, a replacement will be necessary. If the battery is fully charged per the battery charger you can proceed to the next step. With the engine turned off, connect a multimeter to the battery and confirm whether or not it has between 12.2 and 12.6 volts. If it doesn't fall in that range, it either is not fully charged or it is defective. If it falls in that range, the next step is a load test. With a helper starting the vehicle, confirm that while the vehicle is cranking, the battery voltage doesn't fall and remain under 10 volts (below reserve capacity) during cranking (there may be an initial drop that will jump back up during cranking). If the voltage stays under 10 volts the entire time the engine is cranking, it is either not full charged or it is defective. Once the engine is running, confirm the battery voltage is between 14 and 14.5 volts. If it is below 14 volts, either the battery is defective or the alternator is not working properly. If the battery passes all of the aforementioned tests, it is good.

How Many Volts Should A Car Battery Have?

A fully charged automotive battery should have between 12.6 and 14.7 volts with the vehicle off. When the engine is running the voltage should be between 13.7 to 14.7 volts.

When To Replace Car Battery

Most standard car batteries last between 4-6 years. Once the life of your vehicle battery is beyond that time, you can choose to replace it in anticipation of preventing the eventual no-start situation or wait until it goes bad. The most common symptom of a bad battery is a slower starting engine after normal starting in previous days or weeks. However, there may not be an advance warning. Performing a battery test will confirm the battery is bad and that the issue is not another component such as a starter or alternator.
