There are a variety of different battery technologies and chemistries that have become available over the years. Certain battery types proves to be better depending on the application. See below for a run down on all of the major battery chemistries and technologies on the market today. Alpine Power Systems is a leading provider of battery solutions for Critical Power, Telecom, and Motive Power applications.
VRLA Batteries: VRLA (valve-regulated lead-acid) battery technology is a type of battery designed to be maintenance-free while offering high performance and long cycle life. Unlike traditional lead-acid batteries, VRLA batteries are sealed and use a recombinant gas to recombine the oxygen and hydrogen generated during overcharge, thus eliminating the need for regular maintenance.
AGM: The most popular type of VRLA battery. They use a fiberglass mat to immobilize the electrolyte and are sealed, making them virtually maintenance free.
TPPL AGM: Thin plate pure lead battery is a type of lead-acid battery that is primarily used in applications where high levels of power and high cycling performance are required.
Gel: Similar to AGM batteries but use a thick, jelly-like electrolyte instead of the fiberglass mat. They are also sealed and maintenance free.
Flooded-Lead Acid Batteries (FLA): A flooded lead acid battery is a type of rechargeable battery in which the electrolyte is not held in a gel or an absorbent glass mat but is instead held in a liquid solution.
Lithium Ion Batteries: A lithium-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. Li-ion batteries use an intercalated lithium compound as the electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery.
Nickel-Cadmium Batteries: A nickel–cadmium battery, also known as a NiCd or NiCad battery, is a type of rechargeable battery commonly used in consumer electronics. It is composed of nickel oxide hydroxide and metallic cadmium.
Nickel Metal Hydride Batteries: The NiMH battery is made up of a positive electrode composed of nickel hydroxide, a negative electrode composed of metal hydride, and an alkaline electrolyte.
Nickel-Zinc Batteries: A Nickel-Zinc (Ni-Zn) battery is a type of rechargeable battery that utilizes nickel and zinc as its active materials. It is a newer type of rechargeable battery, and is used in a variety of applications including electric vehicles, power tools, and energy storage. Nickel-Zinc batteries have higher energy density and longer life cycles than conventional lead-acid batteries, making them a more efficient and cost-effective choice.
Sodium Nickel Batteries: A sodium nickel battery is a type of rechargeable battery that is known for its high energy density and long cycle life. It is made up of two electrodes: a sodium anode and a nickel cathode. This battery is often used in electric vehicles and industrial applications.
Alkaline Batteries: An alkaline battery is a type of primary battery powered by chemical reactions between zinc and manganese dioxide. Alkaline batteries are common in many household items such as toys, flashlights and remote controls. They are also used in medical devices, communications equipment and other electronic devices. Alkaline batteries provide a longer shelf life and higher capacity than other types of batteries.
