In general,how many years a car battery has been used is as follows:
The normal service life of car batteries is about 2-3 years.
There are two types of batteries for automobiles.One is maintenance-free battery and the other is ordinary battery.
Ordinary batteries are also known as lead-acid batteries.The main advantage of this type of battery is that it is cheap and the voltage is relatively stable.The disadvantages are also obvious and require frequent routine maintenance.It is necessary to check the height of the electrolyte regularly and add distilled water.
Maintenance free battery.It is not necessary to periodically check the height of the electrolyte and add distilled water during the service life.At the same time,it has many advantages such as small size,high temperature resistance and shock resistance.This kind of battery is simple and easy to handle.The downside is that the price is more expensive than a regular battery.
If you want to increase the battery life,you must pay attention to the usual maintenance and care,and do not have the habit of harming the battery.When the battery life expires,it usually feels that the headlights are not lit before,or the car can't fire when the weather is cold.If there is a similar situation,check if it is time to change the battery.
Generally speaking,the original battery of the new car can be used for 3-4 years,but it needs to be replaced after about 2 years.
The life of a car battery is related to various factors such as the condition of the car,the condition of the road,the habits and maintenance status of the driver.The person who lacks the common sense of using the car does not pay attention to the maintenance.It may be broken in half a year.The motor can be fully charged with the battery and the generator can be fully charged.After the car is old,especially after the replacement of the two large-sized motor generators,especially when the original parts are not replaced,the battery is replaced.The time is shorter.
A device that converts chemical energy into electrical energy is called a chemical battery,and is generally referred to as a battery.After discharge,the internal active material can be regenerated by charging-storing electrical energy as chemical energy;and converting the chemical energy into electrical energy when discharging is required.Such a battery is called a battery(Storage Battery),which is also called a secondary battery.
The so-called battery is an electrical chemical device that stores chemical energy and discharges electric energy when necessary.
A battery(StorageBattery)is a device that converts chemical energy directly into electrical energy.It is a rechargeable battery that is recharged by a reversible chemical reaction.It is usually a lead-acid battery,which is one of the batteries.Belongs to the secondary battery.Its working principle:the external electric energy is used to regenerate the internal active material during charging,and the electric energy is stored as chemical energy.When discharging,the chemical energy is converted into electric energy output again,such as the mobile phone battery commonly used in life.
It uses a lead substrate grid(also known as a grid)filled with sponge lead as a negative electrode,a lead substrate grid filled with lead dioxide as a positive electrode,and a dilute sulfuric acid having a density of 1.26--1.33 g/mlg/ml as an electrolyte.When the battery is discharged,the metal lead is the negative electrode,and an oxidation reaction occurs to form lead sulfate;the lead dioxide is a positive electrode,and a reduction reaction occurs to form lead sulfate.When the battery is charged by direct current,the two electrodes generate elemental lead and lead dioxide,respectively.After removing the power supply,it returns to the state before discharge to form a chemical battery.The lead storage battery can be repeatedly charged and discharged.Its single-cell voltage is 2V.The battery is a battery pack composed of one or more monomers.The battery is referred to as the battery.The most common one is 6V.Others have 2V,4V,8V,24V batteries..For example,a battery used in a car(commonly known as a battery)is a battery pack in which six lead batteries are connected in series to form a 12V battery.
For traditional dry-charged lead storage batteries(such as automobile dry-charged batteries,motorcycle dry-charged batteries,etc.),distilled water should be added after a period of use to keep the dilute sulfuric acid electrolyte at a density of about 1.28 g/ml;for maintenance-free batteries,It is no longer necessary to add distilled water until use is terminated.
Chemical principle
The equation is as follows:
Total reaction:Pb(s)+PbO2(s)+2H2SO4(aq)reversible symbol 2PbSO4(s)+2H2O(l)
When discharging:negative Pb(s)-2e-+SO42-(aq)=PbSO4(s)
