Buying a battery that appears the same won’t suffice when it comes to replacing your automobile battery. There are numerous types and sizes of batteries for automobiles. In this section, we present a clear and concise explanation. This author has been thoroughly vetted and is qualified to write about this subject matter.

Make no fear, we’ve got your back. The answer to the question “what size battery do I need?” is A. Please feel free to peruse our site.A battery must be of the correct dimensions to fit in a device. Fortunately, group sizes make it simple to find the ideal one.You’ll also have to decide between wet cell and VRLA batteries. The liquid electrolytes in the former may require some light maintenance. The latter does not require any liquid and is completely self-contained.The world of battery types and group sizes is waiting for you if you’re up for it.

Let’s start with the basics, shall we?

Wet Cell Or VRLA – Which Car Battery Type Should You Choose?

Which Battery is Best for the Bike? Dry Cell or Wet Cell

Wet Cell Car Batteries

The phrase “flooded” or “wet cell” is entirely up to you. No matter how you look at it, these are the original lead-acid batteries made for automobiles.What’s up with that?

Because they’re long-lasting, inexpensive, and easy to maintain. To be “properly-maintained,” a wet cell battery must be inspected every few weeks, which is the one major drawback.You’ll want to check the water level in a wet cell battery, which generates electricity. Because water is lost during the charging process, you’ll need to top it off with distilled water around once every month.Fortunately, it’s just a matter of unscrewing the cap and adding a few drops of distilled water.

However, “semi-solids” are a term for sealed wet cell batteries that don’t require any maintenance.SLI and deep cycle wet cell batteries are the two options available.To put it simply, they’re in charge of everything to do with getting the vehicle up and running. To get the car started, this provides a quick surge of power through the ignition system. The lights and the ignition are also powered by these batteries. After that, the alternator is responsible for keeping everything going.A deep cycle is the second possible variant (also known as a marine battery).Wet cells are designed for quick bursts of electricity, where they never run out of energy. Even if the battery is depleted by up to 80 percent, deep cycle batteries can be recharged numerous times.

VRLA Car Batteries

A VRLA is the name given to the second kind of automobile battery (Valve Regulated Lead-Acid). Because they are sealed batteries, no gases or liquids may leak in or out of them. A VRLA automobile battery has both its strengths and weaknesses. In order to keep it in good working order, it has been completely sealed and cannot be repaired. Replacement is the only option if there is an issue with it. There are also no liquid electrolytes in VRLA automobile batteries; they instead use gel or AGM. Gel electrolyte VRLA batteries are extremely long-lasting. Shock, heat, and vibration aren’t a problem for them. Virtually identical to gel cells, but the electrolytes are housed in glass mats rather than gel. These are constructed out of a mesh of very fine fibers. To keep the electrolytes from spilling, this forms a dry material. What is the best kind of car battery for you?

This is when the number of people in the group comes into play. Your owner’s manual explains that your car was built with a specific battery in mind. Using the recommended battery eliminates the need to worry about things like cold cranking amps (CCA) and reserve capacity (RC) (RC). There are a variety of battery group sizes, so let’s take a closer look.

Car Battery Group Sizes Explained

Battery Group Size | How to Choose Your Battery | Autobatteries.com

The number of people in the group can tell us a lot. Each terminal is located at a specific distance from the battery’s center of mass. Whichever category it belongs to, you can be sure that it is exclusive to the vehicle in question. An industry standard was used to determine the measurements. For automobile manufacturers, this makes it easy to construct the engine chambers around. Thanks to an on-board display, you don’t have to dig around for a tape measure to see which group size your battery belongs in. Included among these are:












General Motors is an example of a car manufacturer that caters to particular demographics. Side-post batteries, with group numbers such as 70, 74, 75, and 78, are frequently used by General Motors. This demonstrates that the group number not only indicates the battery’s size but also its design. Side-post, recessed top, and American standard are a few examples. When comparing different designs, it’s important to keep in mind that some of them don’t have protruding posts, like recessed top batteries. Similar to a top-post, a side-post also has posts on the side. It’s as simple as looking at the unit for the group number and replacing it with one that matches thanks to the battery group sizing system. The owner’s manual, on the other hand, should always be checked in the event that the erroneous part was previously installed.

What Happens If You Install The Wrong Sized Battery?

You certainly haven’t read this text if you install the wrong battery size. It’s possible that you purchased the wrong size, in which case it won’t fit properly in position. Even if it does, you’re not out of the woods yet. As an example, let’s use the American standard. The ports may be too close to the hood of the car if you install one in a vehicle designed for a recessed top. This can generate a spark, an electrical short, or even a fire if it isn’t handled correctly. To begin with, why risk it? Consult your car’s owner manual to find out which battery size group it was designed for.
