Of course, it's better to be maintenance-free. If it's maintenance-free, you don't need to constantly remember to check the battery's fluid level, as long as its power isn't very low.
Maintenance-free battery: - means that under normal conditions of use, it is not necessary to add battery water (electrolyte or distilled water); this means there is no need to charge for a long time; the battery is used continuously and the battery has sufficient power. Maintenance-free batteries literally require no maintenance. In fact, this is not the case, even maintenance-free batteries need to be maintained in case of abnormal use. After a maintenance-free battery has been used for a period of time, the moisture in the electrolyte will gradually decrease due to temperature changes, resulting in insufficient starting current or difficultydump. the battery must be opened to check the electrolyte capacity. When the electrolyte is insufficient or dried, distilled water should be added to each cell filling hole in time. The amount of water in each cell must be the same. After adding water, apply a small amount of sealant to the edge of the sealing cover and seal the cover tightly to prevent leakage. Different battery manufacturers have different regulations. Some manufacturers stipulate that maintenance-free batteries should be inspected and replenished every 30,000 miles, while others stipulate that maintenance-free batteries should be inspected and replenished every 50,000 miles.
How long does it take to turn off the car after the car battery is dead?
How long does a car battery last?
Battery lifecar battery is 2-4 years.
Ordinary car batteries use lead-acid batteries, their life is basically 200-500 times, and the life is about 2-4 years. years .
Cars with automatic start-stop function are equipped with special batteries. The service life will be higher, 400-800 times, and the service life is basically 4-6 years.
New energy vehicles use lithium batteries, which have a longer lifespan and can be used for 5-8 years.
Generally, batteries are used during charging, which is equivalent to shallow charging and shallow discharging, which extends the cycle time.
The lifespan mentioned above refers to a completely depleted and fully charged battery. An ordinary car battery can be charged and discharged 200 times.
These incorrect operations resulted inwill cause a reduction in battery life
1. Long-time driving over short distances.
For example, the place where you work and where you live are very short, one kilometer, which is particularly harmful to the battery.
Because when the car starts, the engine uses the starter to drive the ignition, and the starter depends entirely on battery power to operate. By driving back and forth frequently for short distances, the battery was exhausted and the car would start, but the driving time was too short and the battery had not had time to recharge. In this way, the battery will easily lose power over time and the number of charging cycles will increase, which will affect the battery life.
2. Frequent starting.
In winter, the temperature is relatively low and the activity of the battery itself is not very good. If shee doesn't start at first time, if it restarts and starts a few more times, the battery will be seriously hurt. Frequent starting has a significant impact on battery discharge and will also shorten its lifespan.
3. Do not turn off the electrical appliance before extinguishing the flame.
The main symptom is that the headlights forget to turn off after the engine is turned off. Many carsThere is no auto power off function after the car is turned off. The lights may stay on all night, but the next morning it will be tragic. The door cannot be opened and the engine cannot be started.
How many years does a car battery last?
The normal lifespan of a car battery is generally around two years. It can be extended with proper maintenance, and the best ones can last over 4 years.
Let me tell you a few things to note:
1. When starting the car, each start time should not exceed 3-5 seconds, and the interval between restarts should not be less than 10 seconds.
2. Frequently driving the car for short distances, starting and stopping, will cause the battery to be undercharged for a long time and shorten its service life. Driving at a constant speed on the highway for 20 to 30 minutes can give the battery enough time to charge.
3. During daily driving, before leaving the car, check and ensure that all car lights and other electrical devices (such as radios and CDs) are turned off. Because it might drain your battery.
4. If the battery is depleted and requires a jump start (also called hardwiring) to start, you should immediately drive at a constant speed (such as highway speed) forat least 20 to 30 minutes. charge the battery.
5. When the battery is completely discharged, borrowing a light may not help you start the car. At this point you need to use a special battery charger for slow charging.
6. If the car is left unused for a long time, it must be fully charged first. At the same time, start the car every two months and run it at medium speed for about 20 minutes. Otherwise, if left too long, it will be difficult to start.
7. Understand battery usage time. If used for more than 4 years, replacement is recommended.
Please adopt it if you think it's right.
How long does a car battery last?
Your battery has been used for more than two years and has reached the end of its life. The battery is described as the electrical power stationof the car. Battery life is typically around 2-3 years. If used and maintained properly, it can be used for more than 4 years. If used and maintained improperly, early damage can occur within a few months.
When the battery is used, the electrolyte level should be checked regularly, and the storage status of the battery should be checked and replenished timely. Battery maintenance is relatively simple. Replenishing electrolyte, cleaning the battery and poles, and checking the battery density can effectively extend the life of the battery. Due to the widespread use of maintenance-free batteries, batteries generally do not require maintenance under normal operating conditions.
1. Clean the exterior of the battery
2. Check the battery fluid level
3. Refill the batteryelectrolyte
4. Check the electrolyte proportion.
According to the different performance of the battery during charging and inspection, the internal fault of the battery and its causes can be determined.
(1) Normal state. When the battery is charged, the battery voltage and electrolyte density increase in a certain pattern, and the electrolyte temperature is not high. This indicates that the technical condition of the battery is normal, but it is excessively discharged and needs to be recharged.
(2) State of vulcanization. When charging an internally vulcanized battery, the cell voltage may initially reach around 2.8 V, and the electrolyte temperature is also high. As charging continues, the cell voltage will drop to 2.2V after a few hours and then slowly rise again. the battery charging rules are the same. For batteries that are highly sulfated internallyeur, the voltage of a single cell will be higher than 2.8 V and the density of the electrolyte will not increase at the beginning of charging, the battery will bubble.
(3) the active substances fall. When charging a battery with significant active material losses, the electrolyte will be cloudy, the battery capacity will be reduced, the charging time will be shorter than that of a normal battery, and phenomena such as Boiling of the electrolyte and end of charging will also occur. earlier.
(4) Self-discharge. Self-discharging batteries take a long time to charge, and the electrolyte density and terminal voltage increase slowly. If there is a serious short circuit inside the battery, no matter how long the charging time is, the electrolyte density and terminal voltage will not increase, and there will be no no bubbles in the battery, and the electrolyte will be like a pool of stagnant wateryou.
Most maintenance-free batteries have a hole-shaped hydrometer on the cover that changes color based on changes in the density of the electrolyte.
When the battery hydrometer is green, it means the battery has enough power; when it shows a “dark” area, it means the battery needs to be charged; when it shows a “bright” area, it means the battery is green. means the electrolyte is too low and the battery has been charged. Waste must be replaced.
When the hydrometer of a maintenance-free battery shows the “light” zone, it means that the battery is about to be scrapped. Even if it is recharged, its lifespan will not be long. Recharging at this time can only be used as a temporary measure.
Generally speaking, how long does a car battery last?
The lifespan of aoriginal car battery is 3-4 years, and the life of an ordinary car battery generally lasts 2-3 years. Battery life is related to the configuration of the vehicle and electrical equipment. For example, it is equipped with navigation system, multi-screen information display, remote anti-theft, and the functions are frequently used. continues to consume power when the vehicle is turned off, resulting in prolonged battery discharge, which will damage the battery. The battery warranty period is 1 year, being careful not to waste power will prolong the service life. drums.
Detailed information
Battery maintenance
Batteries are more afraid of low temperatures. In low temperature environments, the battery capacity is much lower than that at normal temperature. Therefore, we must check and enteretain in time, and pay attention to the following points in daily life:
1. Avoid parking the car in an open-air parking lot for a long time if it is parked. for a long time, the battery should be removed and removed to prevent damage from freezing.
2. The car engine is not easy to start in winter, and the starting time should not exceed 5 minutes each time. seconds, the restart interval should not be less at 15 seconds. If it still does not light up after several starts, the cause should be looked for in other aspects such as the circuit, ignition coil or oil circuit. Avoid starting multiple times without interruption, as this may cause the battery to drain due to over-discharge.
3. The car battery should be charged frequently. If the battery is not used for a long time, it will dischargewill slowly manage until it is scrapped. Therefore, the car must be started from time to time. to charge the battery.
4. Clean the battery terminals from time to time and apply special grease to protect the wiring harness. Always check accessories and connection lines on the battery.
5. It is prohibited to use car electrical appliances after the car is turned off. Using the battery alone when the engine is not generating electricity will damage it.
Reference documents:
Use life:
It can basically be used for more than 3 years when the rear load of the vehicle generator is normal and the electrical appliances have no leakage or earthing.
Maintenance :
1. Any operation of using electrical equipment in the car for a long time after stopping the engine will cause excessive discharge of the battery. For example, if you forget to turn off the car lights after parking at night and the engine cannot start the next day, this is largely because the battery is exhausted because the lights are not on. extinguished in time. this time, battery performance may have been significantly reduced.
2. When the engine starts, the battery will discharge with high current, but long-term high current discharge will greatly damage the battery. Each startup time should not exceed 5 seconds. If it is started twice in a row, there should be an interval of 10-15 seconds.
3. After turning off the engine, try to avoid using electrical equipment such as stereos, DVDs, radios,lights, air conditioners, etc. for a long period. If you must use electrical equipment, it is best to start the engine and use the generator to provide electrical power.
4. Since the raw materials used to make batteries cannot be 100% pure, there will always be some impurities mixed in, so batteries will inevitably discharge automatically. The anti-theft alarm also needs electricity after the engine stops. Therefore, for vehicles parked for a long time, the battery may also be over-discharged. If the vehicle is parked for more than a week, please remove the negative battery connector and cut off the power supply.
5. In addition, you should try to avoid using the car battery with high-power external electrical equipment. Such equipment consumes a large amount of energy andmay cause excessive battery discharge. If it must be used, it is best to start the engine while in use, and the generator and battery will provide power together.
How long does a car battery last?
Generally 2-3 years. Ordinary batteries are also called lead acid batteries. The electrodes of lead acid batteries are composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low price; the downside is frequent daily maintenance. Ordinary old-fashioned batteries generally have a lifespan of about 2 years, and the electrolyte level should be checked regularly and distilled water added.
Maintenance-free batteries, as their name suggests, are “maintenance free”. There is virtually no need to replenish distilled water during its life. Healso has the characteristics of impact resistance, high temperature resistance, small size and low self-discharge. Of course, relatively speaking, its price will be more expensive than ordinary batteries. As for lifespan, the recommended replacement cycle for maintenance-free batteries is approximately 3 years under normal circumstances.
From the point of view of use and maintenance, whether your car is equipped with a maintenance-free battery or an ordinary battery, the normal lifespan is about 2 to 3 years. As for extending the service life, ordinary batteries can be added electrolyte after about 3 years of use, extending the service life by 1-2 years. As for maintenance-free batteries, it's best to just replace them, because they exist. Basically, no need to repair them.
Car battery life
The rated life of the batteryttery is 27 months. Generally, family cars are more economical. Many new car batteries last 3 to 4 years, but they are generally used. after replacement. It should be replaced in about 2 years. Taxis are relatively expensive and a single bus lasts around a year, while a double bus lasts around 8-10 months.
Several factors that affect battery life are: vehicle condition, road conditions, driver habits.
Generally, the newer the car, the better the battery life, because the motor is easy to use and saves battery, and the generator is easy to use. The battery can be fully charged when the car becomes old, especially after replacing the two large parts of the engine and generator, due to the huge price difference between the original. and the refurbished products of these two products on the marche, it is easy for car owners not to replace the original parts, then the battery will be more likely to break.
Off-road batteries are often easily damaged. Car batteries have a technical index to indicate the anti-vibration performance of the battery! If the battery meeting the standard vibrates frequently in poor working environment, it will definitely be damaged.
The battery is more likely to be damaged when a woman drives than when a man drives, because female drivers generally do not have the common sense to operate a vehicle.
How long does an electric vehicle battery last?
The lifespan of an electric vehicle battery is several years. In fact, it does not vary, sometimes it is longer.
1. The battery in a battery car usually lasts less than two years. This is what the insiders sayr deceive the layman. I have fooled many people with a fully enclosed battery. General batteries can be repaired by adding battery recharge fluid.
2. The so-called fully enclosed battery is the same as an ordinary car lead-acid battery and can be repaired by adding battery recharge fluid. Battery recharge fluid costs 2 yuan per bottle and is available in motorcycle parts stores, about 450 ml. One bottle can usually repair a battery car, a set of 4 batteries. The cost is 2 yuan and the profit is more than 200 yuan. No wonder there are so many thieves stealing batteries now.
3. Operation process: First open the battery cover, there are 6, cover the small hole with a rubber cap and remove it with the white absorbent cotton around it. Use an injection syringe, and add approximately 25 ml ofAdditional liquid in each small hole (depending on the lack of liquid in the personal battery. Be careful not to exceed the upper tray, otherwise the liquid in the charger will be full, as the liquid will boil during charging. Add more as needed there are too many, remove them). Pay attention to the ventilation of the small holes, otherwise you will not be able to add them. Wipe up surrounding leaks, restore the cap, and use absorbent cotton. Wrap the battery with tape. At this point, your battery can be used for another two years.
Once the car battery is exhausted, use the car's generator to fully charge the battery. The car engine must maintain a speed above 2000 rpm and it takes at least 4 hours to drive. the car.
If the engine speed does not reach 2000 rpm, it will take longer to fully charge. The car's generator should run at one speedspeed above 2000 rpm to reach full load. At this time, the electricity production reaches the nominal value indicated on the nameplate.
The car battery is discharged and requires external ignition. Connect the positive terminal of the battery to the positive terminal of the power supply and the negative terminal of the battery to the negative terminal of the power supply. starts the car. It is not recommended for inexperienced novices to do this themselves, in case they accidentally put the wrong electrode and damage the car.

Notes:
1. a car battery fails, there will be virtually no obvious early symptoms, and the consequences will directly lead to the engine starting incorrectly or even failing to start. The problem should be resolved by replacing the battery with a new one.
2. Generally, theThe nominal lifespan of batteries in formal businesses is 24 to 36 months. However, actual battery life varies greatly due to different usage conditions. For example, many new household car batteries can be used for 3 to 4 years, and some can be used for 2 to 3 years. For example, some high-end cars are equipped with many electronic systems.
3. Before parking and turning off the engine, you should turn off various electronic devices in the car, such as the car's radios, lights, and other equipment. If the system is not turned off, the equipment will remain. function and consume. Regarding the car battery, when you wake up the next day and want to use the car, sometimes you can't turn on the car no matter what, and the dashboard will keep showing that the battery is dead.weak.
