After discharging the battery to 10.5V, discharge the battery deeply with the bulb for 1-5 hours. Then use a dedicated battery activation instrument for activation and maintenance.
First, check the battery, then find out the problem battery, and use the battery with the same capacity, voltage, self-discharge rate, and internal resistance to match the battery, and then use it again.
Water loss is the most common problem and is easier to repair. First, pry off the cover above the battery, open the rubber cover to expose the vent, and then use a dropper to suck distilled water into the battery through the vent. Cover the vent of the water-filled battery and cover the vent with a breathable protective cover to prevent dust from falling into the vent. The principle of rehydration is to take less but not more. If it's not enough, you can add it. If the dosage is too much, the acid ratio will be reduced and the battery capacity will be insufficient.
Vulcanized batteries are repaired with special repair tools. By measuring the state of the battery, it continuously emits positive and negative frequency conversion particle waves during charging and discharging. It takes 10 to 20 hours to remove hard lead sulfate that has crystallized in the battery.
If a single battery short circuit or fault is detected, please use a soldering iron to open the sealant of the single battery. Remove the connecting strips at both ends of the single battery, and then take out the board group of the single battery. According to the situation, correct the curvature of the plates or replace them with new plates. After that, the repaired batteries must be charged separately. Finally, the whole battery pack should be charged, and the relative density of the electrolyte of each battery should be adjusted.
Use a multimeter to measure the open circuit of the battery, and then use 100A to detect the battery voltage 0V as the open circuit. Use a single measurement method to measure open circuit and weld.
Lead-acid battery, the electrode is mainly made of lead, the electrolyte is a kind of battery with a sulfuric acid solution. The lead-acid battery is a kind of power supply with the most mature technology, the largest consumption in various fields, the largest market sales, and the longest service life in China. The lead-acid battery used in electric bicycle belongs to lean liquid type, low type valve-controlled sealed type, and square power lead-acid battery.
Each type of battery has the ability of electrochemical conversion, that is, the stored chemical energy is directly converted into electrical energy. As for the secondary battery (another term is also called the rechargeable portable battery), chemical energy is converted into electrical energy during the discharge process, and the electrical energy is converted into chemical energy during the charging process. This process can be charged and discharged more than 500 times according to the electrochemical system.
Green new energy electric vehicles such as pure electric vehicles, hybrid electric vehicles, electric sightseeing vehicles, electric sweepers, electric cleaning vehicles, electric patrol vehicles, etc., as well as walking cars, lawnmowers, ball cars and medical equipment, Baby carriage, scooter, Forklift, tractor, carrier, underground mining locomotive. As a professional lead acid battery supplier in China, Tianneng Group can provide you with high-quality lead-acid batteries that are suitable for various occasions.
Low price: the price of lead-acid battery is 1 / 4 ~ 1 / 6 of the price of other types of batteries. One time investment is relatively low, most users can afford it.
The battery life can be prolonged by keeping proper charge and discharge. Maintaining 10% - 90% of the lithium-ion battery power is conducive to protecting the battery. It is not necessary to reach the maximum value when charging the batteries of digital products such as mobile phones and laptops.
Lithium-ion batteries’ charging temperature range: 0 ~ 45 ℃, discharge temperature range: 0 ~ 60 ℃.
Lithium-ion batteries must avoid overcharging in the process of charging. Any form of overcharge of the lithium-ion battery will lead to serious damage to battery performance.
There is no so-called "memory" phenomenon in a lead-acid battery, and the performance of the lead-acid battery will not be affected if the charging is interrupted. However, in the case of power loss, long-term storage has an impact on battery life. The longer the storage time is, the greater the impact is.
There is a strong corrosive sulfuric acid solution in the battery, please keep away from children. Please take protective measures during safety inspection. If acid splashes on the skin or clothes, it should be washed with a large amount of water immediately. If it is serious, it should be sent to the hospital for treatment.
The positive and negative poles of the battery can not be short-circuited or reversed, which will easily lead to fire and other major accidents.
When the battery is charged, hydrogen and oxygen are produced, so it can't contact sparks. In summer, the battery can't be exposed to the sun.
It is strictly forbidden to over-discharge, under charge, and overcharge during use.
Initial charging. New or long-term storage batteries should be discharged for the first time before use. The steps are as follows:
① First, screw out the water cap to remove the seal of the small hole on the cover, so that the air is unobstructed.
② Add the prepared electrolyte with a density of 1.285 (note that sulfuric acid should be slowly injected into distilled water when preparing electrolyte), and add it to 10-15mm above the partition plate.
③ After the electrolyte is added, the positive and negative electrodes of the battery and the positive and negative electrodes of the power supply can be connected and ready to discharge after standing for 2-3 h.
④ The initial charging is carried out according to the current and time specified in table 2-59. In the first stage of current charging, the terminal voltage of each small cell was increased to 2.4V, and then the second stage current charging was used until the voltage and electrolyte ratio did not change within 3 h.
Do not short circuit the battery. When the positive and negative electrodes of the battery are electrically contacted by external materials, the battery will be short-circuited. For example, the battery without a package in the pocket will be short-circuited due to contact with metal materials such as keys or coins.
Install the battery correctly so that the polarity mark of battery ("+" and "-") corresponds to the mark of the electric appliance correctly. If the battery is incorrectly installed in the appliance, it may be short-circuited or charged, resulting in a rapid rise in battery temperature.
Don't try to charge the battery. Charging the primary battery that cannot be charged will generate gas and heat inside the battery.
Do not force discharge the battery. When the battery is forced to discharge, its voltage will be lower than the design performance and gas will be generated inside the battery.
Do not heat or directly weld the battery. When the battery is heated or welded, the heat will cause a short circuit inside the battery.
Battery power loss: the power generation system fails and cannot be charged normally, resulting in battery power loss; the battery power has been consumed by the on-board computer and anti-theft system; the battery has lost its power storage capacity (failure).
Starting circuit - including abnormal operation of starting motor, engine, etc.
Ignition system - spark plug, etc.
Oil way - blocked oil way, etc.
Extremely low temperature - battery discharge capacity is greatly reduced, and the engine oil viscosity is greatly increased, the battery is required to provide more starting power. It is very difficult for the car to start under the condition of "cutting the length of the car".
When the engine starts or runs at a low speed, the electronic system in the car is provided by the battery because the generator does not generate electricity or the voltage is very low. During the normal operation of the engine, the generator supplies power to the electrical equipment and charges the battery at the same time. At the same time, the battery is also a large capacity capacitor, which can absorb the instantaneous high voltage generated in the circuit in the car, to protect the electrical equipment in the car.
If the battery is only low but not damaged, it can be charged by lapping another fully charged battery. Or, about 30 minutes after the car starts, the engine can also charge the battery. But if the engine or electrical system parts are damaged, the battery can't be recharged, and repairmen and service stations are equally helpless. Therefore, if the battery continues to discharge, please check the electric steam system before replacement. Sometimes, it's the electrical system rather than the battery itself that causes the battery to fail to charge. If any part of the steam system is damaged, the new battery will continue to consume and you will be in trouble.
Climate conditions - the actual service life of the battery will be significantly shorter in areas with higher temperatures.
Generator output voltage - too high will cause overcharge, too low voltage will cause insufficient charging.
Driving habits of car owners - when the engine is not running, use the electric appliances in the car for a long time, or often forget to turn off the electrical appliances.
The wrong fit - choosing a battery with a low capacity will shorten its service life.
Serious vehicle leakage - serious leakage will significantly increase the burden of the battery and greatly shorten its service life.
Battery pack size - the best battery size for your vehicle. Many vehicles can accommodate multiple battery packs.
Cold start current (CCA) - CCA is the key to good starting performance. It is the current produced by a battery when the battery voltage drops to an unusable level within 30 seconds at 0 ° f (- 17.8 ° C).
Reserve capacity (RC) - in the event of an alternator failure, the reserve capacity helps to power the vehicle's electrical system. Reserve capacity determines the number of minutes of battery life that the battery can supply without dropping below the minimum voltage required for vehicle operation.
In general, the higher the CCA and C20, the better. However, if you live in a cold climate area, CCA performance is an important factor to consider when choosing a battery. On the contrary, if you live in a tropical high-pressure area, you don't need to consider high CCA values.
Please refer to your vehicle manual for the manufacturer's recommendations:

After the emergency starting of the flameout vehicle, it is necessary to drive to 4S shop or battery store to replenish or replace the battery.
Generally, the normal starting time of the vehicle is less than 3-5 seconds. If the vehicle has not started within 5 seconds, stop starting immediately and wait for 10 seconds to start again.
When the engine is not running, try not to use the vehicle's electrical appliances (audio, lighting, etc.).
Before leaving your car, turn off the electrical appliances first, and then turn off the engine.
If the car is not used for a long time (such as more than 2 weeks), it is recommended to disconnect the negative connection to reduce the power loss of the battery.
Note: this operation is not allowed for vehicles with a trip computer to avoid losing information.
Regularly go to 4S shop or professional car repair station for inspection.
It is difficult to start the vehicle. It needs more than one ignition. I feel that the starting power is insufficient.
When the engine is not running, press the horn several times. If the sound is weak, it indicates that there is no power stored and needs to be replaced;
When the engine is not running, turn on the headlamp for 5 minutes. If the headlamp changes from light to dark, it indicates that there is no power stored and needs to be replaced.
Please check at the battery business site.
Generally, the service life of the battery is 2-3 years. It is recommended to replace it during this period, to ensure your safe driving.
Store batteries in a cool, dry environment.
Make sure that the battery is fully charged and make up power about once every two months.
Any terminal corrosion cleaning work may affect the performance of the battery, and there may be potential safety hazards. Brush the terminals and connection clamps with a diluted solution of baking soda (sodium bicarbonate) to remove corrosion. Brush with anti-oxidation grease, and then reconnect and bolt the connecting clip.
Lithium-ion batteries generally use lithium alloy metal oxide as the cathode material, graphite as negative material, and non-aqueous electrolyte as the battery.
Generally speaking, the most commonly used power batteries are lithium iron phosphate battery, lithium manganese oxide battery, lithium cobalt oxide battery, and ternary lithium battery (nickel cobalt manganese ternary)
During the charging process, lithium ions are separated from the positive electrode and then embedded into the graphite material of the negative electrode to form the graphite intercalation compound of lithium-ion. During the discharge process, lithium ions are separated from the graphite intercalation compound a re-embedded into the cathode material.

Sequence: connect the battery and then the power supply when charging. When fully charged, unplug the power supply, and then disconnect the battery and charger. Keep the key door closed when connecting the battery to the vehicle.
Overcharge danger: Unplug the charger power supply after full charge, and do not charge for more than 8 hours continuously.
Do not charge in a sub-zero temperature environment.
The exclusive lithium battery charger should be used when charging, and roadside fast charging is not allowed. 48/60/72v charger cannot be mixed.
During the charging process, if the battery is hot, stop charging and use, and replace the battery in time.
The charger and battery should be far away from the bedroom, avoid combustibles, and keep dry.
For long service life of a battery, it is necessary to:
Check whether the charger parameters meet the requirements of battery charging parameters;
Check whether the battery and the electric vehicle match. If the new battery matches the electric vehicle, the cumulative riding time of the battery is 1.5-2 hours. If it is less than 1.5 hours, the service life of the battery will be seriously affected. The shorter the accumulated riding time, the shorter the service life of the battery;
In the process of electric vehicle starting, slow starting is helpful to prolong the service life of the battery;
In the process of battery use, the maintenance of a single charge and single discharge every six months is helpful to extend the service life of the battery.
Generally, there is no need. Although there is a certain period from the factory to the beginning of use, the battery has a certain amount of self-discharge, but the self-discharge capacity is not large, only the mileage is a little less at the first time, and the remaining 20% ~ 30% of the power can be used for recharging. It is required to cut off the power supply of the electric door lock, and the battery must be fully charged at one time.
The storage battery must be fully charged before storage, and the battery must be supplemented once a month in the future, to avoid the battery capacity decline due to the long-term battery short of power storage due to the sulfation of the plate, affecting the service life of the battery, or even scrapping.
In winter, when you use electric vehicles, you will feel that the continuous mileage will decrease significantly (more obvious in the North), which is a normal phenomenon. Because of the low-temperature environment, the battery activity is reduced, resulting in the low-temperature environment of the battery capacity decreased, in the normal temperature environment, the battery capacity returned to a normal state. Therefore, consumers should avoid leaving the electric vehicle outdoors overnight or charging in a low-temperature environment when using it in winter.
Avoid exposure to the sun under high temperature and strong sun, and do not charge in the high-temperature environment;
Avoid charging immediately after driving under high temperature, and prevent charging time too long (about 8 hours in normal condition);
When the battery is charged, if the power box is hot or does not turn to green light, it is necessary to check and maintain the battery or charger in the battery store or after-sales service network of our company.
No, you should charge in time when the battery is low. Although the battery has voltage limiting protection by the controller, the battery voltage rises after a moment of static, and it can ride for a short time. Such use will cause the greatest damage to the battery, which will cause battery over-discharge and seriously affect its service life.
If the poor quality charger, fault charger, charger with high maximum charging voltage parameters or too long charging time are used, the water loss of the battery will be aggravated, the electrolyte will dry up prematurely, which will easily lead to the deformation of charging drum and the service life of the battery will be terminated in advance.
not always. When the battery is aging and its capacity is reduced, the driving range will be shortened. However, the following problems that are not related to the battery will also lead to the shorter driving range:
The mainline is too thin and the tire pressure is insufficient;
When the efficiency of the motor decreases, the useless work is increased and the power consumption is wasted, which shortens the driving mileage;
The poor quality charger undercharges the battery every day, resulting in the insufficient capacity of the battery, resulting in a decrease of the continuous mileage day by day;
The bad controller makes the starting current of the electric vehicle too large, which makes the driving mileage of the electric vehicle short;
The friction coefficient of each moving part of the inferior electric vehicle is too large, or the mechanical transmission resistance is too large, which can also cause waste of electricity, and lead to shorter driving mileage, etc;
The storage battery shall not be close to an open fire or high-temperature heat source, shall not be thrown into the fire or immersed in water, and shall not be directly exposed to the sun or charged.
The battery shall not be placed in a closed container and shall be well ventilated.
If the battery shell is found to be cracked or leaking, the battery must be replaced.
The electrolyte is an acidic solution. If it gets on the skin and clothes, it should be washed with plenty of water immediately. If it is serious, it should be sent to the hospital for treatment.
The battery shall not be short-circuited or used upside down.
The power supply box is too sealed, and the hydrogen produced at the end of battery charging cannot escape;
The power connection line is loose, aged, or exposed. When the key is turned on and discharged, sparks are generated in the circuit due to uneven road vibration to ignite hydrogen;
The fuse holder on the power box is loose, which causes heat or sparks during the battery charging and discharging process, which ignites hydrogen and causes gas expansion and breaks through the battery cover;
The power box should not be too sealed in the design. Some convection ventilation holes with a diameter of about 1cm should be set at the upper and lower parts of the battery box to facilitate the discharge of gas generated during charging;
If there is no ventilation hole in the design of the power box, the ventilation hole must be reserved during the installation;
Regularly check the power wiring to prevent loosening, aging, or exposure;
If the fuse holder is loose and aged, replace it in time
When the pointer of the electric power indicator on the electric vehicle is at or near the lowest position, charging the electric vehicle is the best, which is beneficial to the service life of the battery. If the daily driving mileage is within 5-10km, it is recommended that you do not charge every day, that is to say, do not short mileage and charge frequently. Otherwise, the service life of the battery will be terminated earlier.
When one or several batteries of your electric vehicle are out of order, the battery should be replaced as a whole. The battery with fault should not be replaced separately. Only use special equipment for testing when maintaining the battery. Especially remind you: one or several batteries should not be used for other purposes!
No, the electric vehicle often vibrates due to uneven road surface during use. If the charger vibrates, its component parameters will drift, which will affect the charging performance and even damage the battery (undercharged or drum charged battery). Therefore, it is strictly forbidden to carry the charger with the vehicle.
The four major parts of an electric vehicle: battery, motor, controller, and charger are the core (main device part) of the electric vehicle. The best performance of electric vehicles can be brought into full play only when they are used together reasonably. No matter which device has problems or the relevant parameters do not meet the requirements of mutual configuration, the electric vehicle will have a short driving range and the battery life will be terminated in advance. So it's not all about batteries that electric vehicles don't run long.
Large capacity and high specific energy: it is made by special technology, the capacity is more than 100%, and the specific energy is 35-40wh / kg;
The self-discharge rate is very low, using high-quality alloy grid and ultra-pure electrolyte, the self-discharge rate is very small and the water loss is very small;
Long cycle life: high efficiency of sealing reaction and long life. The cycle life of 25 C in normal use exceeds the national standard. According to the regulations, the service life is longer;
Safe and reliable: adopt the safety valve with unique design, durable service time, and superior safety performance;
Fully sealed leak-proof structure: the battery can be used in any direction (except inversion), which has the advantages of fully sealed valve control and maintainability;
Optimized design: adopt button type or plug-in cover plate to make battery maintenance more convenient, regular maintenance can greatly extend the service life of battery;
It can be used in various forms: floating and recycling.
