He laid the groundwork for the first rechargeable batteries and discovered the principle that a battery can be recharged again by passing a reverse current through the battery.

This invention has not changed till today and lead acid batteries are still widely used as car starter batteries. Before more than 40 years, the first sealed, valve regulated lead acid batteries were invented. Both absorbed glass metal and gel cell batteries later started to replace wet cell batteries in portable applications. Today we can say that battery market is not going to change in the near future.

Lead acid battery, thanks to the low manufacturing costs, is still the best solution for car batteries and will continue to be for at least few years.

Lead acid batteries consist of multiple single cells. The approximate voltage of a single cell is 2. Lead acid batteries come with different capacities and sizes. For example, one of the most common 12V lead acid batteries consists of 6 single cells. Battery storage capacity depends on the size of the plates and amount of electrolyte. To increase the capacity of lead acid battery, multiple batteries can be connected together in parallel. Cycle life of a deep cycle lead acid battery can vary dramatically based on depth of discharge and type of battery wet cell, gel cell, AGM.

The cycle durability of lead acid battery can vary from cycles and even more. However, this number can vary based on the type, quality and size of the battery. The self-discharge rate of a lead acid battery depends on the storage temperature, same as with other types of rechargeable batteries.

AGM lead acid batteries have very low self-discharge rate of approx. Lead acid batteries should not be completely discharged, as it can damage the battery. As deeper a lead acid battery is going to be discharged, as less cycle life it is going to provide. For example, starting batteries can be fully discharged just few times, while some special valve-regulated deep cycle batteries can be fully discharged and provide even up to life cycles.

It is also easy to determine state of charge of lead acid battery using several simple methods , so you can always tell the charge state of your battery. Low and high temperatures are going to decrease lifespan of the battery. The approx. If a battery is not fully charged the electrolyte may freeze at low temperatures. Lead acid batteries are mostly used as starter batteries in transportation, for example in cars and motorcycles.

Large lead acid batteries are used as backup power supplies for objects that need a permanent power source like hospitals, telecommunication buildings and other places. Valve regulated lead acid batteries are used in portable appliances as backup power sources, for example for computers and servers. Portable lead acid batteries can be found in many vehicles like electric bicycles and motorcycles.

Valve regulated batteries are also used for high power portable flood and work lighting. The popularity of lithium-Ion batteries is growing each year, however lead acid batteries are not going to be replaced by lithium-Ion batteries in the near future , because lead acid batteries are much cheaper to manufacture.

Lead acid batteries are mostly used in high end portable flood lights and solar flood lights that require a lot of power , and can also be found in some mid-range flood lights. Lead acid batteries are used to power flood lights and are much less used in other lamp types with much lower light output like spot lights. Lead acid batteries are used to power portable lights with up to thousand lumens and are often used to power light packs of 2, 4 or more lamps that are capable of producing multiple thousand lumen brightness and are often used in lighting systems.

The closest competitor to lead acid battery is lithium-ion battery, especially lithium phosphate. Which battery type is used in which high power flood light usually depends on the manufacturer views.

However, currently lead acid batteries are more popular than li-ion batteries in high power flood light and lighting systems because of their lower costs. As lead acid batteries are mostly used in high end flood lights which price range start from approx.

Lead acid batteries used in flood lights come with wide range of capacities and sizes, starting from 4Ah up to 50Ah and more. Lithium-ion also known as li-ion currently is the most common rechargeable battery type. Older lithium batteries used lithium metal, but due to its instability and safety issues lithium ions were used instead. Lithium-ion batteries offer number of advantages over other type of batteries such as high energy density and low maintenance, which makes them the best solution for widely used portable applications such as laptops, smartphones, digital cameras and others.

Lithium-ion batteries have various types that are used for different applications. Each of these Lithium-ion batteries uses different cathode materials, so each of them has different pros and cons. For example, li-cobalt batteries are the most popular ones and are used in laptops, smartphones and similar devices, while li-phosphate batteries are used in electric vehicles and portable lighting.

In a li-ion battery when discharging ions travel from negative electrode to positive and in reverse when charging. Lithium-ion battery consists of:. Li-ion battery structure. Lithium cobalt oxide LiCoO 2 batteries are mostly used in common portable electronics like laptops, tablets, smartphones, digital cameras and other. Li-cobalt batteries have high specific energy density , which means that they can store more energy based on the mass of the battery.

However, they need special monitor systems to ensure proper safety, they have lower specific power and lithium-cobalt batteries have shorter life and cycle span than competing types of lithium-ion batteries. Lithium manganese oxide LiMn2O4 batteries have high specific power and they are used for devices that require high power discharge, for example power tools and electric vehicles.

These batteries have lower internal resistance, so they can charge and discharge at higher rates. Li-manganese batteries also are safer and can provide better life span than li-cobalt batteries.

However, li-manganese batteries have lower capacity than li-cobalt batteries. Lithium Iron Phosphate LiFePO4 batteries are used in variety of electronic products, starting from portable consumer electronics to electric vehicles. Li-phosphate batteries are also the most common type of lithium-ion batteries used in portable flood lights. These batteries are safer than Li-cobalt and Li-manganese batteries, they have better life span and can produce high currents more powerful than li-cobalt.

However, li-phosphate batteries have one of the lowest capacities lower than li-manganese of all lithium-ion battery types. NMC batteries use nickel manganese and cobalt combination as a cathode material. NMC batteries provide good specific power and high capacity , they have good life span and temperature tolerance , and these batteries have decent safety compared to li-cobalt batteries. NMC batteries try to combine the best features of other lithium-ion batteries.

The first experiments and developments of lithium battery started in early 20th century, however, the first lithium batteries for commercial purposes were made just in s. These were primary batteries non-rechargeable and metallic lithium was used as anode material instead of lithium ions. Metallic lithium is reactive material, so lithium metal batteries caused serious safety issues. Because of this, scientists started to use non-metallic lithium ions to produce safer lithium batteries.

The first commercially available lithium-ion battery was introduced by Sony in Since then the market of Li-ion batteries has developed and grown rapidly and today lithium-ion batteries provide much better performance and higher capacity. Also an important factor in progression of lithium-ion battery is the reduction of its price.

The first Li-ion batteries were very expensive to manufacture, a lot more expensive than Ni-Cd or Ni-MH and lead acid batteries, but progression of technologies and materials used in these batteries allowed to improve their performance, while at the same time reducing manufacturing price of Li-ion batteries. In the first lithium iron phosphate batteries were introduced that are being used in different portable applications, including portable lights.

Today, lithium-ion batteries are used in variety of industries starting from consumer electronics smartphones, laptops, tablets etc. Lithium-ion battery is certainly the battery of the future and new materials and technologies of lithium-ion batteries are introduced each year that further improves capacity, power, life span and safety of these batteries.

Lithium-ion batteries come in various shapes and sizes , starting from small, coin shaped cells to large battery packs used in electric vehicles. Lithium batteries are available in same common AAA and AA sizes, however, usually lithium-ion cells come in packs of many to form a larger battery usually prismatic shaped that can be used for different electric appliances, including portable lighting.

Lithium-ion batteries used in portable devices such as laptops, smartphones and tablets come in many variations of shapes and sizes, and are specially designed for different manufacturers and products.

Based on the type of lithium-ion battery, charging and discharging rates, self-discharge and charging temperatures can vary significantly. When lithium-ion battery discharges, ions travel from negative to positive electrode, and in reverse direction when charging. To charge a lithium-ion cell, a same polarity higher voltage gets applied to the battery, which makes the lithium ions move from positive to negative electrode. Lithium-ion batteries are better charged in lower than higher temperatures.

When battery gets charged in large heat, it can reduce batteries life span or even damage the battery. It takes about an hour to fully charge most common Li-ion batteries used in consumer electronics.

These rates can vary depending on different factors like age of the battery and temperature in which battery is stored. Older lithium-ion batteries will have larger self-discharge rate.
