AGM batteries are common and found in many applications such as RV batteries, boat batteries, motorcycle batteries, ATV batteries, and UPS & Telecom batteries for generators.
Absorbed Glass Mat is a specially designed glass mat that absorbs the battery electrolyte between the battery plates. AGM batteries contain only enough liquid to keep the mat wet with the electrolyte, and if the battery is broken no free liquid is available to leak out, making them a safer option.
Abbreviation for Valve Regulated Lead Acid battery. There is a mechanism that is regulated by a valve, which allows for the safe release of hydrogen and oxygen gasses when you charge the battery. VRLAS are fully sealed, and found in toy batteries, alarm batteries and mobility scooter batteries.
Similar to the AGM Battery, the Gel Cell contains an electrolyte which has a silica additive that causes the gel to set up or stiffen. Gel cell batteries are best suited to very deep cycle applications and can last slightly longer in hot weather. When it comes to charging, you need to be certain the charger you are using is right for the battery, otherwise, it is certain to ruin it.
Gel Cell batteries are more expensive than AGM and other lead-acid batteries and not as common. They are most suitable for deep discharge situations such as wheelchair and mobility scooters, trolling motor batteries, and RV deep cycle batteries. 
Also known as NiCd batteries, this is a type of wet cell battery and was invented back in the 19thcentury, making it one of the oldest types of rechargeable batteries . NiCad batteries can supply extremely high currents and can be recharged rapidly, thanks to their low internal resistance and the very good current conducting properties. They often come in packs of two, four or eight.
NiCad batteries have a long service life and are often found in solar garden lights, cordless phone handsets, drills, photography equipment, and even toys. Despite this, they lost a large portion of their share in the market due to the popularity of lithium batteries.
This is a serviced battery that allows the liquid electrolyte to move around in the cell compartment. The user can add distilled water to the individual cells as it dries out. This is an engine start, tractor or deep cycle battery.
This battery is most commonly found is motorcycles, golf carts, ATVs and emergency backup systems.
Sealed batteries are a type that does not require the user to fill it with water, as it has been designed to ensure that the acid in the battery is sufficient enough to sustain the chemical reaction, assuming normal use is maintained throughout the warranty period.
There are many different types of sealed batteries, including VRLAs. Sealed batteries are found in engine starting and limited starting/deep cycle applications.
One of the most commonly used batteries today. Lithium-ion batteries are a rechargeable battery where lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Lithium batteries are smaller and lighter than lead acid batteries as they don’t contain lead. They do have some issues with overheating.
As we mostly know, Lithium-ion batteries typically found in phones, laptops, and tablets. But they can be used in larger applications such as motorcycles, EV’s and solar power storage systems (residential and commercial).
