Deep Cycle Battery
This battery type, known as lead acid, comes in sealed or flooded versions. They’re designed to last a long time due to their special build. These batteries have thick plates inside, along with dense paste and wide separators. They contain antimony in the alloys, making them suitable for deep cycle use. The thick plates help resist wear from repeated charging and discharging, making them perfect for marine vehicles, golf carts, and RVs. They can sustain power for a long time with a steady low current supply.
Advantages | Disadvantages |
Designed for continuous discharge and recharge | More expensive than standard car batteries |
Ideal for marine, RV, and renewable energy applications | Not suitable for starting vehicles |
Longer lifespan than regular car batteries |
SLI Battery
SLI stands for Starting, Lighting, Ignition. These batteries are the most common type used in vehicles worldwide. These batteries are made to provide a big burst of power quickly, especially when starting the engine. After the engine starts, the alternator takes over, giving power to the car’s electrical systems and charging the battery again.
Advantages | Disadvantages |
Specifically designed for starting, lighting, and ignition (SLI) applications | Not designed for deep discharges |
Commonly used in conventional gasoline vehicles | May degrade if deeply discharged |
Provides high bursts of power | Limited cycle life |
VRLA Battery
VRLA battery means Valve Regulated Lead Acid Battery. It’s small and easy to store. They’re super safe and need very little upkeep. These batteries have a special valve system that helps manage oxygen. When the positive plate makes oxygen, the negative plate soaks it up, preventing too much hydrogen. This makes water, which keeps the battery moist.
There are two types of VRLA batteries, Gel cell and AGM (Absorbed Glass Mat). AGM batteries are better than Gel cells and regular ones. They charge 5 times faster and last 3 times longer. AGM batteries are great for cars with special features like brake energy recovery and automatic start-stop. Gel cell batteries are tough against bumps and vibrations and last a long time.
Gel Cell Battery (Dry Cell Battery)
Gel cell batteries were created to be spill-proof versions of regular flooded batteries. These batteries are similar to flooded batteries, but instead of using antimony, they use calcium in the lead plates. They also add silica to the electrolyte solution, which turns it into a gel. This gel helps the battery last longer and makes it better at handling vibrations and shocks.
While you can still buy gel batteries, improvements in AGM batteries have made them more popular, reducing the use of gel batteries.
Absorbent Glass Mat Battery (AGM Battery)
The AGM battery is a special kind of battery made for modern cars that need a lot of electricity. It’s similar to a regular wet cell battery, but it uses a fiberglass separator to hold the liquid inside. This type of battery works better than other kinds because it can charge much faster and last longer. It can also handle being used and recharged more times. The AGM battery is great for cars with features like automatic start-stop and energy recovery from braking. However, it can be more expensive, costing 40-100% more than regular batteries.
Advantages | Disadvantages |
Maintenance-free (sealed design) | More expensive than flooded lead-acid batteries |
Versatile applications (telecommunications, UPS, etc.) | Susceptible to thermal runaway if overcharged |
Minimal risk of acid spills | Limited to moderate current discharge rates |
Silver Calcium Battery
These batteries have a special feature as they resist corrosion and stay strong even in high temperatures. The silver calcium battery technology makes them last longer and maintain strong starting power. However, they need a specific charging voltage and won’t work well in vehicles that don’t support it. It’s important to install these batteries only in vehicles designed for them. They are powerful, reliable, durable, and can handle corrosion and high temperatures.
Advantages | Disadvantages |
Improved performance and longevity compared to traditional lead-acid batteries | Higher cost than standard lead-acid batteries |
Less prone to corrosion | Sensitive to overcharging |
Low self-discharge rate | Limited availability compared to other types |
Enhanced Flooded Battery (EFB)
The EFB battery is a better version of the regular wet cell battery. It has a liquid inside but is sealed and made to last twice as long when used and recharged many times. The EFB battery can help start the engine about 85,000 times, while regular batteries can only do it about 30,000 times. It’s not as advanced as the AGM battery but is still a good choice for cars with basic start-stop features.
Advantages | Disadvantages |
Enhanced durability and cycling capabilities | Not as advanced as AGM or lithium-ion batteries |
Lower cost compared to AGM batteries | Requires periodic maintenance (checking water levels) |
Suitable for vehicles with start-stop technology | Limited availability in certain markets |
Lithium-Ion Battery
This special battery works for many small devices and electric cars. It’s called a lithium-ion battery, and it’s great because it’s small but holds a lot of energy. Inside, there are parts called the cathode and anode with something called lithium. The battery moves the lithium around, creating electricity. It’s light, charges fast, and lots of people like using it for cars, phones, and laptops.
