Daily maintenance of lithium batteries:
1. Because the new lithium batteries will have a little power, so users can use it directly when they get the battery, and use the remaining power to run out before charging. After 2 to 3 normal use, you can completely activate the lithium battery activity.EssenceHere are a reminder: Do not misunderstand the rumors of salesperson or on the Internet. New lithium batteries should be activated for up to 12 hours when they are used for the first time.
2. There is no memory effect in the lithium battery. You can use it with it. However, it should be noted that the lithium battery cannot be excessively discharged. Excessive discharge will cause irreversible capacity loss.When the machine reminds the power, it will start charging immediately.
3. In daily use, the newly charged lithium battery should be put on hold for half an hour, and the charging performance is stable before use, otherwise it will affect the battery performance.
4. When the instrument is not used, be sure to remove the battery and save it in a dry and cool place.
5. Pay attention to the use environment of lithium batteries: The charging temperature of the lithium battery is 0 ℃ ～ 45 ℃, and the discharge temperature of the lithium battery is -20 ℃ ~ 60 ℃.
6. Do not mix the battery with metal objects to prevent metal objects from touching the positive and negative pole of the battery, causing short circuit, damage to the battery and even danger.
7. Do not knock, acupuncture, stomach, modification, sun -sun battery, do not place the battery in the microwave, high -voltage and other environments.
8. Use a regular matching lithium battery charger to charge the battery. Do not use inferior or other types of battery chargers to charge the lithium battery.
Do not need to store lithium batteries for a long time
1. The lithium battery should not be charged by 50%to 80%for a long time, and removed from the instrument and stored in a dry and cool environment, and charged a battery every 3 months to avoid being stored for too long.As a result, the power is too low, causing irreversible capacity loss.
2. The self -discharge of lithium batteries is affected by the ambient temperature and humidity. High temperature and wet temperature will accelerate the self -discharge of the battery. It is recommended to store the battery at a dry environment of 0 ℃ ～ 20 ℃.

The production process of the battery
Pole
1.First of all, the polar plates inside each battery must be weighed and the polar plate is matched.The capacity of each cluster is equal, otherwise the group with a small capacity will be fully charged because the capacity will be fully charged in advance.Ending voltageStill continuing charging, a group that causes a small capacityOver -chargingIf the battery is discharged, the small capacity of the capacity is gone in advance. The other battery end has a high voltage, and the total voltage of the battery has no electricity to terminate the protection voltage.Overdischarge. The battery is charging and discharge, and the failure of charging will affect the service life of the battery. However, the small battery groupbattery capacityFurther decline, the decline in the battery capacity further charged and discharged the group, which caused the battery capacity to quickly decrease and scrap. 2.Treatment of weighing front pole plate
Before the polar plate weighing, you must clearly delete the excess in the production of the board, the excess active substances of the burrs and the excessive active substances when applying the ointment.Use the polar plate to brush the headset to brush the excess impurities on the polar plate and welded it to prevent it from causingVirtual weldingAs well asFake weldingEssenceThe pole plate is uneven, the powder is severe, and the polar plate is holes. 3.How to weigh the pole
When the polar board is called the reorganization group, it is necessary to first call a part of the pole plate discharged on the workbench according to the weight of the weight.The weight of the chip pole plate is placed with the pole plate placed on the workbench according to the weight of the pole plate, so that some troubles are avoided.(Positive plate orNegative plateThe smaller the weight difference of each group, the better, the error of 10 to 14AH should not exceed 1 gram of each group, and the error of 17 to 20AH should not exceed 2 grams per group. Coating
1.After weighing the pole plate, the weight is mixed in accordance with the regulations. After the group is equipped with a group, the panel is used for the panel.In the middle of the board, if the position of the pole plate is accurate, placed in the polar box.
Kodi partition
2.Double bags on the panel, use a thin partition tablet to hold the positive plate together, do not bagNegative plateThis can avoid short circuits caused by single -chip partition defects.Single -chip bag, use the partition only packaging the positive plate, not packing the negative plate in the panel box, which is convenient and simple.Lead parts selection and processing
1.Leading parts have lead stules and chops, and are cast with special molds.Generally, it is about 450 ° C. The temperature is too high in the temperature. The lead parts are severely crack due to the severe contraction.The lead parts make should be kept as much as possible. If so, pruning is trimmed.
1. The welding of the cluster, welding is to form the positive and negative lead welding together to form a cluster. The tools that are connected to the pole and the flowing flow together are oxygen-acetylene.
2. Put the wrapped pole plate in the cluster box, insert the pole plate in the cluster box into the comb, first insert the negative pole to the positive pole, so that the polar ears are completely inserted into the comb.If you are not in place, organize it by hand, and then put the stalls, bridge columns, and pole columns between the positive and negative ears.
3. OpenWeldThe acetylene and oxygen are ignited and the appropriate size is adjusted.Move the welding torch and the electrode to the position of the polar ears, and then melt the lead strip and pole ears. After the flowing row is basically welded, the pole pillar andbusbarWelded together.If there is impurities such as lead ash and other impurities when welding, it will find outFake weldingAs well asVirtual weldingThe chilves and flow discharge welding are key processes in the production process. The welding is solid, no virtual welding, and fake welding.At this time, we must remove the impurities while welding, and finally fill up the flow. 4. After welding the flow stream, the detection has no defects and then enters the slot process. Generally, it must be installed in a cluster with terminals, and the back is installed in other clusters.+ -, +-,+ - -series, do not install the wrong polarity.
When the polar plate is installed, it must be installed to the bottom, and then it is normal to detect whether the bridge column is normal. If it is hand -handled by hand, whether the upper cover can be covered with the basic cluster and the groove has been completed.
5. How to check the polar group, first of all, let's usemultimeterMeasure whether the battery is short -circuited.Battery short circuit, Check the cluster to find the short -circuit position for repair.Check that there is no short -circuit, the universal surface positive and negative pole is not negatively displayed. If so, it proves that the polarity is reversed and then re -loaded into the battery slot. 6. Entering bridge welding without failure through the pole plate, polar group welding is the key.Use bridge welding clip column and welding the bridge column with oxygen.When welding, the flame should be guaranteed not to burn to the battery shell, and ensure that there is noFake weldingAs well asVirtual welding, Extraceled from the cluster, it can be smooth.The battery cover is sealed and usedEpoxy glueCompare with a ratio of 2: 1 in conjunction with curing agent.The matching glue should be used in a timely manner to avoid long -time solidification. The colonization of the colloid has a great relationship with the temperature. The higher the temperature, the faster the solidification, so use it as soon as possible.There is also the cover of the heating equipment. 7. After the battery cover is completed, the chilled pillar welding should be performed to detect whether the pillar led to the pillar is in the middle of the hole.Set the chopped mold on the leading column and then melt the pole pillar with oxygen welding.There is also a kind of welding. Put the terminal on the leading pillars.WeldWelded the terminals and pillars together.Pay attention when weldingVirtual weldingAs well asFake welding. Electrolyte configuration
1.280±0.005g/cm3((25℃).
② The container that prepares an electrolyte must be acid -resistant and temperature -resistant with glazed ceramics, glass tanks, plastic grooves or lead -fabral grooves. When preparing, the staff must wear protective equipment;
Wash the utensils before preparing, and wash it with pure water;
PreparationElectrolyteAt this time, put the pure water you need to use in the container first, and then slowly inject concentrated sulfuric acid into the pure water, and constantly stir. It is strictly forbidden to inject the water into the sulfuric acid to avoid splashing burns. Conversion formula is D25 = DT+0.0007 (T-25)
D25: 25 ℃ Electrolytic solution concentration DT: The electrolyte concentration when the temperature is T
1. The composition of the electrolyte is mainly distilled water and sulfuric acid. When configuration, the container must be acid -resistant and clean.
2. Staff must have a sense of safety and wear acid -resistant gloves and clothes at work.Once there is a sulfuric acid splashing on the skin during operation, it should be cleaned repeatedly with water in time.Pour the distilled water into the clean container when configured, and then slowly importConcentrated sulfuric acidAnd use acid -resistant tools to stir.If the temperature is too high to stop adding acid to prevent excessive temperature from splashing, it can be equipped with 1.1: 28 with a temperature of 25 ° C.During the configuration, it is strictly forbidden to pour water into the acid. 3. According to the sourbattery capacity, The capacity of the battery case, the density of acid, the configuration loss in the charging and discharge can be calculated, because the acidity is not poured outward after the charging and the charging is charged. Inject electrolyte
When the exhaust bolt is unscrewed, be sure to penetrate the breathable holes on the bolt. There are sealing cushions and sealing paper under the thrust.
The temperature of the electrolyte must be cooled to below 30 ° C, and the battery must be poured into the battery;
Inject the prepared electrolyte into each cell. The liquid level of the plastic case battery should be flush with the "max" mark on the case. The liquid level of the rubber tank battery should be 10-15mm higher than the partition plate;
Tighten the exhaust embolism to prevent the omissions.
