It’s better suited to recreational vehicles, golf carts and marine vehicles - which is why it’s also called a marine battery. The deep cycle battery type is designed for sustained power with a lower current draw over extended time periods. It uses a thicker battery plate in its cells and has a denser active material. The deep cycle battery is a type of lead acid battery and can be flooded or sealed. However, it can cost 40-100% percent more than conventional batteries. The AGM battery is ideal for vehicles with automatic start-stop applications and with braking energy recovery. It can also cycle down to 80% of its DoD. It can charge up to 5 times faster and withstand 3 times more cycle life than a conventional battery. This battery type performs better than its flooded and gel cell counterparts. It’s similar to a wet cell battery, but a fiberglass separator (a “glass mat”) absorbs the electrolyte solution and keeps it in place. The AGM battery is a VRLA battery designed to support higher electrical energy demands in modern vehicles. You can still find the gel battery on the market, but advancements in AGM batteries have limited its application. It has an increased cycle life and is more resistant to vibration and shock. The gel battery is similar to a flooded battery, but calcium replaces the antimony in the lead plates and silica is added to the electrolyte solution, turning it into a gel. They’re a type of VRLA battery and are also known as dry cell batteries. Gel cell batteries were developed as a non-spillable version of a flooded battery. It was introduced as a lower-tier option to the AGM battery for durability and performance, often used in cars with simple start-stop technology.
The EFB battery can provide about 85,000 engine cranks compared to the 30,000 of conventional flooded batteries. It uses a liquid electrolyte solution, but it’s a sealed battery, designed to take on twice the cycling endurance. The EFB battery is an optimized, higher-performance wet cell battery. However, the silver calcium battery needs a higher charging voltage and can deteriorate quickly from sulfation (damage of battery plates). The silver calcium battery is more resistant to corrosion and more resilient at high temperatures, so it has a longer lifespan in hotter climates. It’s usually sealed and maintenance-free. It’s still a lead acid battery with an electrolyte solution, but uses lead-calcium-silver plates instead of the lead-antimony plates in the conventional battery. This battery type was designed as an improvement over the flooded battery technology. This wet cell battery also experiences a substantial reduction in battery life if it’s discharged below 50% of its depth-of-discharge (DoD). However, the electrolyte solution needs to be topped off periodically, and it must be installed vertically to prevent spillage. It’s a reliable battery for starting engines and provides enough electrical energy to power standard vehicle accessories.

It’s typically made of 6 cells with a liquid electrolyte solution of sulfuric acid and water and supplies a voltage of 12.6V at full charge. The flooded battery is a wet cell battery.
It’s also called the SLI battery, which stands for “Starting, Lighting, Ignition.” The flooded lead acid battery is the oldest car battery type, and it’s very common and affordable. Now, let’s go over the 8 most common types of car batteries available today: 1. Remember, modern cars have varying power needs.Īs such, car batteries also differ to suit those needs. Now that we know the basics of car battery design, let’s go over the 8 most common car battery types: The 8 Car Battery Typesīefore we get into the different types, it’s important to note why there are so many types in the first place.
However, they may have an auxiliary lead acid battery as secondary storage. It doesn’t need to be topped up and won’t spill if tipped over.Ī hybrid or electric car, on the other hand, commonly uses a lithium ion battery.
