Considering the environmental benefits of 12v lead acid battery, several end-user companies and regional governments have also shifted their focus toward the development and implementation of this product for various applications. Having already established its stance in both the automotive and industrial sectors, the lead-acid battery market in recent years has been gaining exceptional importance, given that the product is extremely reliable and cost-effective for critical power supply applications.

Recently, for instance, the Department of Energy’s Argonne National Laboratory has inked an agreement with 14 members of the Advanced Lead Acid Battery Consortium to leverage advanced X-ray technology to increase the potential of lead batteries for various applications. Reports reveal that by using the X-ray beam technology, the governmental body, and the investigators will be benefited with an in-depth understanding of the chemical interactions inside a dead battery while it charges & discharges. Apparently, this would help the mass commercialization of the lead-acid batteries in electric vehicles, energy utilities, and smartphones, eventually driving lead-acid battery market trends.

Despite the growing investment scenarios in the lead-acid batteries, it is imperative to mention that the global lead-acid battery industry has fallen behind the competing technologies of lithium-ion batteries – that have captured a massive chunk of more than 90% of the overall battery market for stationary energy storage. The high energy density and fast charging potential of lithium-ion batteries have made them a good match and a product of choice in the rapidly proliferating business sphere of electric vehicles and power grid, which has significantly brought down on the costs of these batteries. Indeed, the lithium ion battery market held a valuation of over USD 24 billion in 2016.

Lead acid batteries still have huge potential as they do not pose the same explosion and fire risks as that of the lithium-ion batteries, in turn making them more reliable for the stationary power grid and automotive applications. Owing to the increasing focus toward improved power quality, the stationary lead-acid market, according to reliable estimates, is projected to record a y-o-y growth of more than 5% over 2018-2024. The stationary lead-acid batteries, for the record, find prominent applications in the energy utilities, backup power, renewable energy systems, emergency lighting, railway backup systems, security systems, and O&G explorations.

Speaking along similar lines, another important investment ground for potential stakeholders is the SLI lead-acid battery industry. Given the globally increasing automotive sales, SLI lead-acid batteries are catering to the increasing demand for vehicles with the start-stop functionality and micro-hybrid systems. Accounting for more than USD 25 billion in 2017, this segment of the lead acid battery market is expected to garner lucrative proceeds, owing to its growing prominence as a means to lower carbon emissions in micro-hybrid vehicles. On this note, it is prudent to mention that more than 99% of the passenger cars in Europe, as of 2017, were operated on lead-acid batteries, courtesy - Battery Council International (BCI).

Lead has been further considered as the most effectively recycled commodity metal, and the lead-acid batteries in this regard are the only energy storage systems in the form of batteries that are almost 100% recycled. Reports claim that around 99% of lead batteries are collected & recycled in the United States and Europe. Elaborating further, the Europe lead-acid battery market has, in fact, outpaced the annual sales of more than 9 million units in 2017, and is further expected to propel the regional landscape subject to the growing investments and regulations pertaining to renewable power generation, green transport, and emission reduction targets.

Considering the environmental benefits of these batteries, the renowned giants operating in the global lead-acid battery market space have been indulging in product innovation and technological advancements, in compliance with energy and GHG emission targets, which would, in turn, have a powerful impact on the future trends of the overall industry expansion. From a valuation of USD 50 billion in 2017, a report by Global Market Insights, Inc., forecasts the lead-acid battery market to surpass a remuneration portfolio of USD 75 billion by 2024.

Lifepo4 batteries are being used more and more widely because of their high safety, especially in combination power batteries. The lifepo4 battery pack manufacturers have seized its development potential and made relevant research. The parameters of lithium iron phosphate batteries are similar to those of other batteries, but four aspects should be paid special attention to: consistency, self-discharge rate, high rate and long life.

1. If there is a protective plate for the lithium 12v battery packwith poor consistency, its capacity will be the lowest according to the bucket principle. This will cause the whole battery pack to not release enough electric energy because of one battery. Over time, the life of the battery pack will be shorter. If the battery pack does not have a protective plate, not only the capacity will be lost, but also the battery pack will have a short life. There may be safety problems such as  overheating and explosion.

2. Self-discharge rate. Because lithium iron phosphate batteries are often used in power batteries, the power consumption is high, which requires that the self-discharge rate of batteries should be less than 2% per month. To achieve this, the above-mentioned consistency requirements are indispensable.

3. Batteries that can withstand high rate charging and discharging have strong ability of fast charging and discharging. For lithium iron phosphate batteries, it is necessary to be able to charge and discharging quickly to meet the requirements of power lithium batteries.

4. Long life; as a general requirement, lithium iron phosphate has 85% capacity after 1000 discharges of 1C and 80% capacity after 3000 discharges. Of course, the standards set by each lifepo4 battery pack manufacturer are different because of the different technology level and materials.

Implicitly, new energy has been integrated into all aspects of our lives. At present, the use of electric vehicles is more extensive, and electric vehicles are inseparable from battery storage, which provides power guarantee for all electrical systems on vehicles. The degree of electronic and computerized vehicles is becoming more and more powerful, and they rely heavily on storage batteries. Battery poor and power-deficient vehicles will have various failures. If it is serious, it will lead to paralysis of the whole vehicle. All of these require the attention of auto battery factory.

Introduction of New Energy Vehicle Batteries: Lead-acid Batteries and Triple Lithium Batteries

As a mature technology, lead-acid batteries are still the only batteries for electric vehicles that can be mass produced in auto battery factory because of their low cost and high discharge rate. However, the specific energy, specific power and energy density of lead-acid batteries are very low, so it is impossible for electric vehicles powered by lead-acid batteries to have good speed and endurance mileage.

Ternary lithium batteries are lithium batteries using lithium nickel cobalt manganese as cathode materials. Compared with lithium cobalt oxide batteries, they are safe, but the voltage is too low. The energy density is between lithium iron phosphate battery and lithium cobalt 18650 battery. The development trend of new energy automobile batteries in the future is suitable for the weather in the north, and the batteries will be more stable at low temperature.

It is important to choose a reputable manufacturer or brand for the purchase of high-quality batteries; to check whether the automotive battery specs meet relevant standards; to check whether batteries are suitable for use in tropical or temperate climates; and to check whether the manufacturer has after-sales service guarantees. Four simple points are very useful. If you don't understand, please listen to our detailed introduction.

How to choose and buy Automobile batteries?

Automotive batteries are very important for controlling motor vehicles. They start the engine and provide extra power to the engine, lights and accessories. In addition, it provides power to the electronic system when the car is not running. When buying new batteries, there are many things to consider, such as cold start current, reserve capacity and group size.

Types of Automotive Battery

There are two main types of automobile battery: low maintenance and maintenance-free. Maintenance-free batteries usually have longer operating life, faster charging speed and longer shelf life. But they are more likely to cause problems because the material of the movable disk falls off. Low maintenance batteries are more suitable for motor vehicles in hot climates. Because the battery is not sealed, water can be added when needed.

Cold Start Current (CCA)

CCA is a measure of battery capacity for starting a motor vehicle in cold weather. Battery cold start current level should meet or exceed the original standard. If you are not sure about the level, you can check the user manual. If you live in a cold area, you'd better buy a high-level cold start current, because more current is needed to start the engine.

Group size

This involves the external dimensions and the location of the battery terminal power. Vehicles usually have different group sizes and are always purchased according to the recommended size of the automobile manufacturer.

Reserve capacity

Reserve capacity refers to the length of time that the battery can run the car when the alternator is not working. Technically, fully charged batteries can operate at 25 amps. If it's less than 10.5 amps (the minimum requirement for running a car), a new battery needs to be replaced. Car batteries with long-term reserve capacity should be purchased because they are needed in emergencies such as breakdown or failure to start.

In addition to the three main aspects of cold start current, reserve capacity and group size, climate conditions, warranty, installation and price should also be taken into account, which can ensure that you buy the best car batteries.
