The life of a lead acid battery, the life of a lead acid battery

1. Depth of discharge.

The depth of discharge is the extent to which the discharge starts to stop during use. 100% depth means full capacity. Lead-acid battery life is greatly affected by the depth of discharge.

The focus of the design consideration is deep recycling, shallow recycling, or floating. If a shallow cycle battery is used for deep cycle, the lead-acid battery will fail quickly.

Because the cathode active substance lead dioxide itself is not firmly bound to each other, lead sulfate is generated when discharged, and it returns to lead dioxide when charged, and the molar volume of lead sulfate is larger than that of lead oxide, so the volume of the active substance expands during discharge. If one mole of lead oxide is converted to one mole of lead sulfate, the volume increases by 95%.In this way, repeated contraction and expansion make the combination between lead dioxide particles gradually relax and easily fall off.

If only 20% of the active material of one mole of lead dioxide is discharged, the degree of shrinkage and expansion is greatly reduced, and the binding force is destroyed more slowly, so the deeper the discharge depth, the shorter its cycle life.

2. The degree of overcharge.

A large amount of gas is precipitated during overcharging, and the active material of the positive plate is subjected to the impact of gas, which will promote the shedding of the active substance; In addition, the positive grid alloy is also subject to severe anodizing and corrosion, so the battery life is shortened when it is overcharged.

3. The influence of temperature.

The life of lead-acid batteries increases with increasing temperature. Between 10 35, for every 1 elevation, about 5 6 cycles are added, and between 35 and 45, each elevation of 1 can prolong life by more than 25 cycles; Anything higher than 50 reduces the life due to the loss of anode vulcanization capacity.

The battery life increases with temperature within a certain temperature range because the capacity increases with temperature. If the discharge capacity remains the same, the depth of discharge decreases when the temperature rises, and the solid life is extended.

4. Effect of sulfuric acid concentration.

Although the increase of acid density is beneficial to the capacity of the positive plate, the self-discharge of the battery increases, and the corrosion of the grid also accelerates, which also promotes the loose shedding of lead dioxide, and the cycle life decreases with the increase of acid density used in the battery.

5. The influence of discharge current density.

As the discharge current density increases, the life of the battery decreases because the cathode lead dioxide is loosely shed at high current density and high acid concentrations.

Lead-acid batteriesCycle life refers to the repeated charge and discharge of the battery, fully charged to completely discharged as a cycle, with the increase of the number of cycles, the attenuation of the capacity of the lead-acid battery is inevitable, when the battery capacity attenuates to a specified value, the end of life can be determined.

According to the standard of electric bicycle battery, after 300 times of charging and discharging, the remaining capacity reaches 70% of the initial capacity.

That is to say: a group of qualified lead-acid batteries, the normal use of the special ring life is 200-300 times. Therefore, for the daily use of ordinary consumers, as long as the use method is correct, the use time of a good group of batteries is generally more than two years.

Of course, the cycle life of lead-acid batteries is also closely related to the charging and discharging conditions

1. Charge according to the standard current (generally standard charging - that is, the current of the battery capacity), shallow charging and shallow discharge can effectively extend the cycle life of the battery.

2. If the high current (generally fast charging - that is, the current of the battery capacity) is charged, it will affect the service life of the battery, that is to say, the larger the charging current (the faster the charging speed), the shorter the cycle life;

Lead-acid batteries can cope with short-term high-current discharge, and the impact on the life of the battery is not great, but it is afraid of continuous high-current deep charging and discharging.

From a technical point of view, there are many factors that affect the life of lead-acid batteries:

1. There are internal factors such as the composition of the active substance, crystal form, porosity, plate size, grid material and structure;

2. There are also external factors such as discharge current density, electrolyte concentration and temperature, discharge depth, maintenance status and storage time.

GeneralLead-acid batteriesThe service life is three years.

Ordinary batteries are also known as lead-acid batteries.

Its electrodes are made of lead and lead oxides, electrolytes.

It is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low price; The disadvantage is that routine maintenance is frequent.

Protection of lead-acid batteries.

If you want to use the lead-slick acid battery for a long time, you must ensure two points, one is overcharge, and the other is overdischarge. Overcharging and discharging can lead to failures inside the lead-acid battery, speeding up its lifespan. Therefore, after use, try not to charge the battery first, so that the lead-acid battery can get a short recovery, and after the temperature of the battery drops down, it is being charged.

The first is daily maintenance, wipe off the dust, sludge and residual electrolyte on the surface of the battery, keep it clean and dry, and prevent self-discharge.

Remove oxides from the poles and wire joints to prevent resistance from increasing. Maintenance of maintenance-free batteriesThe maintenance-free battery is not really maintenance-free, but it means that this kind of battery does not need to be taken out and charged under normal conditions.

For maintenance-free batteries that can be refilled, distilled water should be supplemented if necessary. Charging of the battery. When the electric eye indicates that the storage of electricity needs to be charged, it should be charged. Turn off the ignition and all electrical appliances before the charging process.

Under normal circumstances, it is not necessary to remove the connecting cable of the battery when charging at a small current (such as renting a charging device with Xiao Zhengyun), but before fast charging, that is, before charging at a high current, the two connecting cables should be removed.

Clip the electrode clip of the charger to the electrodes of the battery according to the regulations, and then connect the power cord of the charger for charging. When charging is over, turn off the charger, then unplug the charger, and remove the charger's electrode clip from the battery.

Lead-acid battery life is generally one and a half years.

Generally, the recyclable life of lead-acid batteries is up to one and a half years, and the lead-acid batteries with better quality can even be recycled for up to two years. However, under normal circumstances, the life of lead-acid batteries begins to decline after half a year of use. Its power will also gradually decrease.

The charging method of lead-acid battery is incorrect, the charging time is unstable, the charging amount is incomplete, the use method is incorrect, and other daily wrong use methods will greatly affect the service life of lead-acid battery. Because the precise charging system and correct usage habits will affect the operation of the battery, it is also necessary to standardize the charging method.

The magnitude of the internal resistance will also affect the life of the battery. The size of the resistance is inversely proportional to the remaining capacity of the battery, when the remaining capacity of the battery is decreasing, the resistance of the battery is also increasing, and the increase and decrease produce a lot of substances at the same time, and the service life of the battery has been greatly affected.

Ways to prolong life

1. Develop the correct battery charging method and daily use mode to avoid insufficient charging amount during charging, or cause overcharging, and also reduce the occurrence of over-discharge behavior.

2. Try to keep the battery away from places where the temperature is too high. The optimal operating temperature of the battery is 25 degrees Celsius, and the reasonable temperature of the battery compartment is to keep it within 22 to 25 degrees Celsius.

3. Conduct regular inspection of the battery, as well as related capacity tests. Reduce the presence of active substances in the battery as well as some impurities that affect the battery power.

Lead-acid battery life is generally 2 years.

The service life of lead-acid batteries is about two years, and its average number of charging and discharging times is about 350 times. This means that a complete charge and discharge will reduce the life of Shouchun. If the owner charges it once in 2 days, the battery can usually last for about two years, and if it is charged in 3 days, the life can be extended accordingly.

However, battery life also has a greater impact on the daily charging habits of car owners. If it is charged every day or incorrectly, it will lead to a shorter battery life and the battery needs to be replaced in advance. As long as the electric vehicle is replaced, the charger needs to be replaced, when the charger is damaged, do not choose the charger casually, try to choose the original charger.

Maintenance of lead-acid batteries

For ordinary lead-acid batteries, special attention should be paid to the usual cleaning work. It is necessary to pay attention to check whether the pole and the chuck are connected and tightened, whether there is any corrosion and burning, and whether the exhaust hole is blocked, whether the electrolyte has been reduced, and if the problem is found, it should be dealt with in time. The starting time of the car should not exceed 3 to 5 seconds each time, and the interval between starting again should not be less than 10 seconds.

If the car is not used for a long time, the car should be fully charged first. At the same time, start the car every other month and run at a medium speed for about 20 minutes. Otherwise, the wide pants will be fast, and if they are left for too long, it will be difficult to start.

The general maintenance-free battery should also be checked frequently, and the problem should be replaced in time.
