Our Car Battery Buying Guide

If you are religious about your car maintenance, make sure to always ask your technician to check the life of your battery when you bring it in for routine maintenance. No one wants to be stuck because of a dead car battery. You’ll need a tow, a friend nearby to get you and some extra cash for a new battery when that happens. There is nothing good to say about that experience.

But you don’t have to experience this and can prevent it by taking several, easy precautions. In addition, when you take the precautions, you can shop for the battery you want without being in a rush. This will save you time and lots of money.

Your first step to preventing that dead car battery situation is to watch your time. There is no definite amount of time that batteries last, but an average of three to five years is what technicians estimate. There are quite a few factors that contribute to battery life: weather, maintenance of the vehicle and frequency of use. It is extremely important to test your battery every year and before you head out on a road trip.  If you buy your car used, make sure the battery that is in it is the appropriate size for the vehicle.

There are also certain things you can look for that indicate neglect. Heavy-duty use can really wear on a battery that is not suited for the technological equipment in the vehicle. Low water levels can damage your battery, as well as intricate mechanical audio or video enhancements in the car. These are all ways to prevent that dead car situation that kills your finances and really isn’t good for your vehicle.

Once you have realized that you are going to need to replace your car battery, you’ll want to know how they work so you can buy the perfect one for you. As most batteries do, a car battery stores energy for your car. Inside the battery is acid that produces electricity when reacting with the lead plates. The bigger the engine, the more powerful battery you’ll need.

Modern cars demand much more out of their batteries because of all the upgraded technology within them, so sometimes even a small vehicle will require a powerful battery if it has lots of electronic features. The Kinetik KHC2400-Watt battery is great for a vehicle with high-end audio systems with a 12-vault power cell.

Your auto manual should assist in figuring out the battery your car needs. There are a few things to look for when buying the best car battery: Automotive battery electrolyte is a term that you should understand. The negative and positive lead plates turn into lead sulfate when the battery discharges. At that point, the electrolyte is depleted in sulfuric acid and become almost entirely water. During the charging process, the positive plate of lead dioxide and the negative plate of lead interact to give the electrolyte back its acidity. This acid is very dangerous so always be sure to wear protective gear when dealing with batteries.

Cranking amps tells the consumer how much the battery’s starting power is. You will need to look in your auto manual to find the CA number for your car battery. The cold-cranking amps is especially important to those operating a vehicle in frigid temperatures. It is the measure of amps deliverable in temperatures below freezing. A battery’s chemical process is significantly slowed down in temperatures below freezing to nearly half of what they are when the temps are warmer.

Maintenance-free is important and also pretty standard with today’s best car batteries. In the past, vehicle owners would have to add distilled water if the electrolyte levels were off. Automotive battery terminals or posts are supposed to be kept clean for optimum performance. When you get your car maintenance, ask the mechanic to clean those for you. There is a cleaning kit you can buy for those as well, so you can clean it on your own. Keeping these things in mind when you buy your next battery is what will save you time and money by extending the life of your battery.
