Understanding Battery Groups

If you’re still confused about battery groups, you’re about to find your answer. Batteries are available in a wide array of shapes and sizes, but what does the group number refer to?

At first, people mostly think the group number refers to the battery’s power, reverse capacity, or similar measurements. However, it’s much easier than that; battery groups refer to the size. They’ve been developed by the Battery Council International (BCI) to make your mission easier when choosing a battery for your vehicle.

Bear in mind that the size only refers to the battery’s dimensions: length, width, and height. It doesn’t have to do anything with the battery’s capabilities. A larger battery doesn’t mean you’ll be getting a better performance; there are a lot of other facts involved.

Don’t let the simplicity trick you, though. The matter isn’t that simple; for example, Group 51 batteries are smaller than Group 34 batteries. So, we’re not looking at standard sizing here.

What does that mean? It means that you must check the battery’s group dimensions and make sure it goes with your vehicle. As you see, the larger group number doesn’t necessarily mean a larger battery.

There’s also one more thing you’ll need to take care of: some vehicles can accept multiple battery groups. If you want to search through a lot of options, it’s better if you check which groups your car is compatible with.

What Else Should You Learn About Batteries Before Choosing?

Group sizes aren’t all that’s there to batteries. There are a lot of other factors that you’ll need to learn about if you want to make the right choice. There’s the terminal configuration, terminal type, polarity, cranking amps, mounting system, and cold-cranking amps for starters. It seems overwhelming at first, but these factors are simple to get a grasp of.

We’re talking about a wide variety of vehicles, including trucks, utility vehicles, go-karts, RVs, and golf cars. A battery may fit in two of those, but it won’t start the engine in either unless you get the other specifications right.

You’ll find BCI codes on most batteries in the market, so you ought to learn about everything you can. There’s also the fact that cars radically vary when it comes to batteries. You may have two closely similar vehicles, but they’ll have different requirements for the battery.

If you live somewhere where it’s cold, you’ll want to prioritize the cold-cranking amps. When the temperature gets low, it affects your battery and its performance. You’ll need a battery with a suitable amperage so that it can run smoothly in cold weather. You can first check the minimum amperage your car requires and then get a battery that matches or exceeds the number.

Battery Power Specifications – A Quick Overview

Besides the size, there are a couple of specifications you ought to consider before buying. The reserve capacity, cold amps, and cold cranking amp are the three vital components of any battery. Here’s a brief about each one of them.

Reserve Capacity

The reserve capacity refers to the number of minutes your battery can keep a constant load when it’s fully charged before it fully discharges. The load is usually a constant of 25 amps.

If we’re talking in numbers, the reserve capacity means the amount of time a charged battery can deliver a current of 25 amps in a temperature of 80°F degrees before it discharges to 10.5 volts.

If you tend to travel a lot, a higher reserve capacity should be your priority. It can make a more significant difference in your experience than the cranking amps do.

Cranking Amps

The cranking amps refer to the power needed to start your car. In numbers, it means the number of amps a fully charged battery can constantly provide for 30 seconds at a temperature of 32° F while keeping the voltage at a minimum of 7.2 volts.

The difference between this rating and the cold-cranking amps is the temperature. The CCA is meant to measure the battery’s performance in cold weather, so the testing is done at 0° F.

Cold Cranking Amps

The cold-cranking amps, otherwise known as CCA, refer to the power your battery can generate to start the engine in cold weather. Low temperatures usually cause the engine to start in a long time. Plus, in severe temperatures, the battery may not be enough to start it, which will get you stuck.

Knowing the cold-cranking amps number gives you an idea of what to expect from your battery in the most severe conditions. If you live in a cold country, you’ll likely have to start your vehicle in temperatures colder than 0°F. Or, sometimes, you’ll need your motor to keep cranking for 30 seconds or more due to the cold temperature.

Only a battery with sufficient cold-cranking amps will work for you in similar cases.

If you have a modern vehicle, you may not face this issue. Modern vehicles generally start in less time than older ones, so the cold-cranking probably won’t be an issue.

An Overview of Different Types of Batteries

Batteries mostly come in three types: enhanced flooded batteries (EFB), lead-acid batteries, and absorbent glass mat (AGM). Here’s a quick overview of each type and its properties.

Enhanced Flooded Batteries

Enhanced flooded batteries are known for their high cyclical stability. It’s higher than that of lead-acid batteries, although they have strikingly similar designs. These flooded batteries provide excellent resistance against vibration and discharging. That’s mainly due to their tough construction and high price.

The high price is justified, though, seeing as enhanced flooded batteries last much longer than your standard batteries.

These batteries are mostly found in vehicles that come with stop-start technology.

Lead-acid Batteries

Most batteries in all vehicles are lead-acid batteries. They’re the common type in and out of the market. Lead-acid batteries have that name because their outer covering is filled with battery acid. Additionally, the positive and negative lead plates in the acid stimulate the battery’s terminals.

Although they’re the most common type, lead-acid batteries aren’t as good as advanced types, such as enhanced flooded and absorbent glass mat. However, they cost much less than the previously mentioned, which is one reason people opt for them. On top of that, they’re suitable for almost all uses.

Absorbent Glass Mat

Absorbent glass mat batteries are the most expensive type on this list and for all the good reasons. They’re the most powerful batteries on the market, and they’re maintenance-free. Imagine not having to top your battery with distilled water and care for it? The batteries are worth every pound, indeed!

AGM batteries are also spill-proof, which eliminates the risk of acid leaking. This feature, in particular, is ideal for off-roading use.

The batteries became popular in the ‘80s; they were first used for military vehicles, which tells you a lot about their power. To this day, they’re used for heavy-duty jobs and vehicles that need high power. Most, if not all, luxury and sports cars come with AGM batteries.

The 4 Best Group 49 Batteries on the Market

Group 49 batteries are used for a lot of different vehicles; they’re mostly useful for start/stop applications. These batteries’ physical dimensions are 15 x 0.6 x 7.5 inches, but the market options could vary.
