Automobile battery life

How long is the life of a car battery?

The service life of automobile batteries is 2-4 years.

Ordinary automobile batteries use lead-acid batteries, the cycle life is basically 200-500 times and the service life is about 2-4 years.

Cars with automatic start-stop function, equipped with special batteries, will have a higher cycle life, 400-800 times, and the service life is basically 4 -6 years.

Lithium batteries for new energy vehicles have a longer service life and can be used for 5-8 years.

Generally, the battery is used while charging, which is equivalent to shallow charging and shallow discharging, which prolongs the cycle time.

The cycle life mentioned above refers to being completely used up and fully charged, and ordinary car batteries can be charged and discharged 200 times.

These wrong operations will lead to the loss of battery life.

1, long-distance driving.

For example, the place where I work and the place where I live are very close, one kilometer, which is particularly harmful to the battery.

Because when the car starts, the engine is ignited by the starting motor, which can only work by battery power supply. I often drive a short distance back and forth. When the electricity runs out, the car starts, but the driving time is too short to charge the electricity. After a long time, the battery is easy to die, and the number of cycles increases, which affects the battery life.

2. Start often.

When the temperature is low in winter, the battery activity itself is not very good. If it doesn't work the first time, you will get hurt if you send it a few times. Frequent start-up has a great influence on battery discharge, and it will also lead to life loss.

3. The electric appliance was not turned off before the flameout.

The main performance is that the headlights are forgotten to turn off after the flameout. Many cars have no automatic power-off function after flameout. The light may stay on all night, and it will be a tragedy the next morning. The door won't open and the engine won't start.

How many years can a car battery last?

The normal life of automobile batteries is generally about two years. Proper maintenance can be extended, and it is best to use it for more than 4 years.

Tell you a note:

1. When the car is started, the starting time should not exceed 3 to 5 seconds each time, and the restart interval should not be less than 10 second.

2. Cars often travel short distances, and when they start and stop, the battery will be under-charged for a long time, shortening the service life. Drive at a steady speed on the highway for 20? 30 minutes is enough to charge the battery.

3. During daily driving, before leaving the car, check and ensure that all lights and other electrical appliances (such as radios and CDs) have been turned off. Because it may drain your battery.

4. If the battery is exhausted and needs to be started by jumping, you should immediately try to drive at a constant speed (such as highway speed) for at least 20 minutes. Fully charge the battery for 30 minutes.

When the battery is completely discharged, borrowing fire may not help you start the car. At this time, it is necessary to use a special battery charger for slow charging.

If the car is not used for a long time, it 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, it will be difficult to do it for too long.

7. Know the battery life. It has been used for more than 4 years, and it is recommended to replace it.

If you think it is right, please adopt it.

How long is the life of a car battery?

Your battery has been used for more than two years, and it has reached its service life. The battery is described as the power station of the car. The life of storage battery is generally about 2-3 years, and it can be used for more than 4 years if it is used and maintained properly. If it is not properly used and maintained, it will be damaged in advance in a few months.

When the battery is in use, the height of electrolyte should be checked regularly, and the storage of the battery should be checked and replenished in time. The maintenance of the battery is relatively simple. Doing a good job of replenishing electrolyte, cleaning the battery and pole piles, and controlling the specific gravity of the battery can effectively extend the service life of the battery. Due to the extensive use of maintenance-free batteries, batteries generally do not need maintenance under normal working conditions.

1. Clean the outside of the battery.

2. Check the battery level.

Replenishing electrolyte

4. Check the specific gravity of the electrolyte.

According to the different performance of the battery during charging inspection, the internal faults of the battery and their causes are identified.

(1) Normal state. When the battery is charged, the battery voltage and the specific gravity of electrolyte increase according to a certain law, and the electrolyte temperature is not high. This shows that the technical state of the battery is normal, but it belongs to overdischarge and should be charged.

(2) Vulcanized state. When the battery with internal vulcanization is charged, the cell voltage can rise to about 2.8V at first, and the electrolyte temperature is also high. As the charging continues, the battery cell voltage will drop to 2.2V after a few hours, and then slowly rise, which is the same as the good charging law of the battery. If the inside of the battery is severely vulcanized, the cell voltage will be higher than 2.8V, and the specific gravity of electrolyte will not increase. At first, the battery will bubble.

(3) The active substance falls off. When charging a battery with serious active substances falling off, the electrolyte will be turbid, the battery capacity will be reduced, the charging time will be shorter than that of a normal battery, and the phenomenon of the end of charging such as electrolyte boiling will also appear in advance.

(4) Self-discharge. Self-discharging battery takes a long time to charge, and the specific gravity of electrolyte and terminal voltage rise slowly. If there is a serious short circuit inside the battery, no matter how long the charging time is, the specific gravity and terminal voltage of the electrolyte will not rise, and there will be no bubbles in the battery. The electrolyte is like a stagnant water.

Most maintenance-free batteries have a hole hydrometer on the cover, which will change color according to the change of electrolyte specific gravity.

When the hydrometer of the battery is green, it means that the battery is fully charged; The "dark" area indicates that the battery needs to be charged; The "bright" area indicates that the electrolyte is too low, and this battery has been scrapped and needs to be replaced.

When the hydrometer of the maintenance-free battery shows the "bright" area, it means that the battery is close to scrapping, and even if it is charged, its service life is not long. At this time, charging can only be used as an emergency expedient.

Generally speaking, how many years is the service life of a car battery?

The service life of the original car battery is 3 to 4 years, while the ordinary car battery is generally 2 to 3 years. The service life of the battery is related to the configuration of vehicles and electrical equipment, such as navigation, multi-screen information display, remote control, anti-theft and so on. Because the battery continues to consume power when the vehicle is turned off, it is harmful to the battery. The warranty period of the battery is 1 year. Be careful not to cut off the power at ordinary times, which can prolong the life of the battery.

Battery maintenance

Batteries are most afraid of low temperature. At low temperature, the capacity of storage battery is much lower than that at normal temperature. So we should check and maintain in time, and pay attention to:

1. Avoid parking in the open-air parking lot for a long time. If it is parked for a long time, the battery must be removed and taken away to prevent freezing damage.

2. It is difficult to start an automobile engine in winter. The time for starting an automobile at a time should not exceed 5 seconds, and the interval between restarting should not be less than 15 seconds. In the case of repeated starting and still not catching fire, the reasons should be found from other aspects such as circuit, ignition coil or oil circuit. Avoid repeated uninterrupted startup, which will cause the battery to burn out due to excessive discharge.

Car batteries should be charged frequently. If it is not used for a long time, it will slowly discharge itself until it is scrapped. So start the car every once in a while to charge the battery.

4. Clean the battery terminal every once in a while and apply special grease to protect the wiring harness. Be sure to check the accessories and connecting wires on the battery.

5. It is forbidden to use automobile electrical appliances after the car is turned off. If the battery is used alone without generating electricity, it will cause damage to the engine.

How long is the life of a car battery? How to maintain it?

Use time:

Under the condition that the backwashing electricity of the on-board generator is normal and the electrical appliances are grounded without leakage, it can basically be used for more than 3 years.

Maintenance:

1. Any operation of using the on-board electrical equipment for a long time after turning off the engine will lead to excessive discharge of the battery. For example, if you forget to turn off the lights after parking at night, the engine will not start the next day. A large part of the reason is that the battery is exhausted because the lights are not turned off in time. At this time, the performance of the battery may have been greatly reduced.

2. When the engine is started, the battery will be discharged with high current, but long-term discharge with high current will do great harm to the battery. Do not start for more than 5 s at a time. If it is started twice in a row, the interval should be10 ~15 s.

3. After turning off the engine, try to avoid using electrical equipment for a long time, such as audio, DVD, radio, lighting, air conditioning, etc. If electrical equipment must be used, it is best to start the engine and provide electricity by the generator.

4. Because the raw materials used to make the battery can't reach the purity of 100%, there will always be impurities mixed in the middle, so the battery will inevitably have automatic discharge. The burglar alarm also needs electricity after the engine is turned off, so the battery may be overdischarged for vehicles parked for a long time. If the vehicle is parked for more than one week, please remove the negative battery connector and cut off the power supply.

5. In addition, we should try to avoid using the automobile battery to connect with high-power electrical equipment, which may lead to excessive discharge of the battery. If it must be used, it is best to start the engine at the same time, and the power supply is provided by the generator and the battery.

How long is the life of a car battery?

Usually in 2-3 years. Ordinary batteries are also called lead-acid batteries. The electrode is composed of lead and lead oxide, and the electrolyte is sulfuric acid aqueous solution. The main advantages are stable voltage and low price; The disadvantage is frequent daily maintenance. The life of old-fashioned ordinary batteries is about 2 years, so it is necessary to regularly check the height of electrolyte and replenish distilled water.

Maintenance-free batteries, as the name implies, are characterized by "maintenance-free". There is basically no need to replenish distilled water during the service life. It also has the characteristics of impact resistance, high temperature resistance, small volume and small self-discharge. Of course, relatively speaking, its price will be more expensive than ordinary batteries. As for the service life, the recommended replacement cycle of maintenance-free batteries is about 3 years in general.

From the point of view of use and maintenance, whether it is a maintenance-free battery or an ordinary battery, the normal service life of your car is about 2-3 years. As for prolonging the service life, ordinary batteries can be added with electrolyte after about 3 years of use, thus prolonging the service life of 1-2 years. As for the maintenance-free battery, it is better to replace it directly and basically do not maintain it.

Automobile battery life

The design life of the battery is 27 months, which is more economical for general family cars. Many batteries in new cars last for 3-4 years, but they must be replaced once, usually about 2 years. Taxis are more expensive. Single bus can be used for one year, and double bus can be used for about 8- 10 months.

Several factors that affect the battery life are: car condition, road condition and driver's habits.

Generally, the newer the car, the less the battery, because the motor is easy to use and the battery can be fully charged. After the old car, especially after the replacement of two large motor generators, the difference between the original products and the refurbished products in the market is huge, so it is easy for the owner not to replace the original accessories, and then the battery is more prone to failure.

Off-road batteries are often easy to break down, and car batteries have a technical index to express their anti-vibration performance! If the standard battery works in a bad environment and often vibrates, of course it is not good.

Female drivers are more likely to damage the battery than male drivers, because female drivers generally lack common knowledge of vehicle use.

How long is the battery life of electric vehicles?

The battery life of electric vehicles is several years, but it doesn't mean that sometimes it will be longer.

1, the battery of a battery car generally doesn't last for two years, which is what an insider says. Fooled many people with fully enclosed batteries. Ordinary batteries can be repaired by adding battery replenisher.

2, the so-called fully enclosed, that is, like ordinary automobile lead batteries, can be completely repaired by adding battery replenishment liquid. A bottle of battery supplement, about 450ml, is sold in 2 yuan Auto Parts City. A bottle can generally repair a battery car, with 4 batteries in a group. The cost of money in 2 yuan is more than 200 yuan. No wonder there are so many small stolen batteries now.

3. Operation process: First pry open the cover plate on the battery, which has six small holes, cover it with a rubber cap and take it away together with the surrounding white absorbent cotton. Use a syringe and add about 25ml of supplementary liquid to each small hole (depending on the lack of liquid in the personal battery, be careful not to exceed the upper plate or the liquid will be full during charging, because the liquid will boil when charging, and it will be pumped if it is added too much). Pay attention to the ventilation of the small hole, otherwise it will not be added. Dry the leakage around, restore the bottle cap and absorb cotton. Wrap the battery with tape. At this point, your battery can be used for another two years.
