What does 12 volt battery mean?

A 12 volt battery is a general term for a class of batteries that commonly have a voltage of 12 volts, and are charge/discharge deep cycle batteries that are often used as starter batteries, and of course you can see him almost anywhere.

12V Lead-acid batteries

(1) 12V lead-acid battery

12V lead-acid batteries are widely used in a variety of machinery and equipment, you can see him, this battery is sulfuric acid as the electrolyte liquid, the electrodes are lead plates.

Advantages ① affordable, 12V lead-acid battery construction is simple, the raw material is also relatively inexpensive, can meet the basic needs of the storage of electricity outside people prefer cheaper batteries, so, 12V lead-acid battery in life more widely used. ② discharge current is large and stable, based on this lead-acid batteries are often used in automobile engines and other engines.

Disadvantages ① low life expectancy, ordinary lead-acid batteries have a life expectancy of about 3 years, because of its simple structure, so after a long time of use, there will be a variety of problems, and the use of the battery material itself also makes this battery cannot be used for a long time.

② more dangerous, because its electrolyte for the flow of acid is highly corrosive, so in the use of batteries, but the battery leakage, gas overflow should be handled with care, because of its liquid electrolyte terminals are also prone to corrosion, the need for regular treatment, the use of distilled water also needs to be filled.

(2) 12V gel battery

Also belongs to a kind of lead-acid batteries unlike the liquid electrolyte rich liquid, colloid batteries use acid colloid, the same use of lead plates to generate electricity.

Advantages ① low maintenance costs, unlike liquid electrolyte, 12V colloidal electrolyte will not leak maintenance infrequent, while the liquid electrolyte so that the battery can only be placed flat, colloidal batteries in addition to the guide you can install his ② high temperature, compared to the liquid-rich lead-acid batteries at high temperatures need to ensure that sufficient distilled water, colloidal batteries can be charged or discharged in high temperature environments.

Disadvantages ① charging and discharging more strict, for charging you need special charge controller to ensure that the charging can not be fast charging, charging overfilled, etc., when discharging you need to always keep at 50% of the power, less than 50% of the discharging will also damage the battery, if you strictly adhere to the rules of the battery’s life is only about 4 years, and at the same time, you charge and discharge will also have other additional costs. Since then gel batteries are less used.

12V lithium battery

Lithium batteries used for charging and discharging are mainly lithium iron phosphate batteries, lithium cobaltate, lithium ternary, lithium batteries are like the new era’s favorite, he is mainly used in a variety of electronic devices and electric vehicle industry. It is a liquid battery, lithium plays an important role in the battery.

Advantages ① high energy density, for the unit density is the amount of stored electricity, lithium battery has a higher storage capacity. ② high battery performance, compared to lead-acid batteries, lithium batteries are more convenient to use, first of all, you don’t have to worry about the battery can not be used when the battery power is too low, lithium batteries can keep the battery in a lower power work, on the other hand, lithium batteries are also faster charging, effectively saving time, while a lithium battery life is also far more than lead-acid batteries.

Disadvantages ① more expensive, lithium battery manufacturing process is higher, the material is also more expensive, so compared to lead-acid batteries lithium batteries are costly and expensive. ② more dangerous, lithium batteries are manufactured differently, in some lithium batteries, but the battery breakage battery lithium in contact with the air, will make the battery instantly on fire, releasing a huge amount of heat, new energy vehicle battery pack extrusion led to half of the car melted.

Conclusion

The use of various batteries should be in accordance with certain standards, battery benefits vary, according to the use of the appropriate battery selection.
