Many batteries used today are lithium-ion batteries. Lithium-ion batteries have no memory performance but are very inert. Activation requires charging for approximately 12 hours. However, manufacturers now perform an activation process before leaving the factory, so new batteries are used. In recent times, it was generally said that the first three adjustment periods do not require 12 hours of charging. When purchasing or purchasing batteries, the seller will tell us that the first three charging periods require 12 hours.
This was the charging time of the previous nickel series batteries. The correct time is 4-6 hours, and it is better to turn off the battery after it runs out and then recharge it, which is natural. After the adjustment period, Re-flush means that after flushing, everything will be fine for another half hour, or about two hourses and a half. The battery typically needs to go through about 10 rinse and discharge cycles. get the best effect! It is normal for 2128 series batteries to have a short standby time after the first few charges. After about 10 charge and discharge cycles, the ideal standby time can be achieved, which is usually around 4 days. The first three times of charging last 4-6 hours, then each time of charging lasts 2.5 hours.
There are two popular sayings about the first three times of charging:
< p>1. Buy a machine When charging, let it charge for more than 12 hours2. Secondly, it is best to charge for 1-2 hours after it is fully charged.
The first is charging the nickel-metal hydride battery. In the past, nickel-metal hydride batteries were used. Since nickel-metal hydride batteries have memory capabilities, iIt is best to recharge them after using them for the first three. times for 12 hours to allow the batteries to be fully activated and achieve good results. This is common practice, so sellers used to say it, but now this has changed.
Lithium batteries do not need to be charged for as long. Lithium batteries are inert, but very small. They have been pre-activated before leaving the factory, so the new batteries always have some power, after three long charging times, they will heal. slowly by itself. Using the battery itself is also an act of battery activation. In addition, the memory capacity of the lithium battery is very low, so there is no need to recharge it after each use. be stable, in order to obtain good results. Lithium batteries have overcharging protectionges. They start with a high current charge, then a trickle charge once full the power is automatically cut off. The effect of recharging is not significant and overcharging may cause a significant discharge cycle. if it is too long, it could damage the battery. This is the case the first three times. You can recharge it and use it later. It is recommended to recharge it after use to extend battery life. In the future, charging will consist of charging for about an hour after a full charge. Frequent charging is not recommended because the lifespan of a lithium battery is related to the number of times it is charged. Generally, the lifespan of a lithium battery varies depending on its capacity, but roughly it is 300 to 700 times, so frequent charging and. discharging affects battery life and is also bad for the charger.
UBattery can be charged and discharged about 500 times. The 2128 series battery is in standby after charging and discharging several times. The time can reach about 4 days, so it can be used for about 3 years. After 3 years, 2128 will have been eliminated, so one stack is enough! Battery life is measured by the number of charge and discharge times. If the battery is charged before it is exhausted, it will shorten the battery life. Generally, the current lithium-ion battery life is about 500 charging and discharging times. It is therefore recommended to exhaust the battery as much as possible before recharging it.
If the user wants to extend the effective use time of the battery, in addition to ensuring the quality of the charger, correct charging techniques are also essential, as poor quality chargers or methods Incorrect charging conditions will affect the batlaugh. Regarding the usage time and battery life, here are the charging tips:
1. Before the battery leaves the factory, the manufacturer has activated and precharged it, so the battery has residual power. Some friends said that the battery is charged according to the adjustment period, but the standby time is still seriously insufficient. This is indeed a real battery, in this case, the adjustment period needs to be extended and then fully charged and discharged 3-5 times.
2. If the newly purchased battery is lithium-ion, the first 3-5 charges are generally called the adjustment period and must be charged for more than 14 hours to ensure full activation of lithium-ion activity. Lithium-ion batteries do not have a memory effect, but have high inertia. They must be fully enabled to ensure optimal performance for future use.
3.Some automated smart fast chargers only indicate that they are 90% full when the light changes. The charger will automatically switch to slow charging to fully charge the battery. It is best to use the battery after it is fully charged, otherwise the usage time will be shortened.
4. Lithium batteries do not need to be specifically discharged before being charged. Improper discharge will damage the battery. When charging, try to charge slowly and reduce fast charging; the time should not exceed 24 hours. Only after the battery has undergone three to five complete charge and discharge cycles will all the chemicals it contains be “activated” to achieve optimal usage.
5. Please use the charger from the original manufacturer or a reputable brand. For lithium batteries, use a special charger for lithium batteries.lithium and follow the instructions, otherwise the battery will be damaged or even dangerous.
6. Many users often leave the phone on while charging. In fact, this can easily harm the lifespan, because during the charging process the circuit board heats up. At that time, if there is an external call, instant reflux current may occur. , which is detrimental to battery life. Internal parts cause damage.
7. Battery life depends on the number of repeated charges and discharges. You should therefore try to avoid charging when the battery has residual energy, as this will reduce its lifespan. When the downtime exceeds 7 days, the battery should be fully discharged and fully charged before use.
8． All batteries discharge automatically. When not in use, nickel-metal hydride batteries discharge chathat day by about 1% of their remaining capacity, and lithium batteries discharge by 0.2% to 0.3% of their remaining capacity each day. When charging the battery, try to use a dedicated socket and do not share the socket with the charger, TV and other household appliances.
9． Although it is within the network coverage area, it is no longer possible to accept andThe call has been initiated. At this time, the unreachable transfer function that can be used will be transferred to the nearby landline to avoid the loss of the incoming call. This method is also applicable when the call is not in the network coverage area or the signal is weak and. cannot be connected temporarily.
10． Do not expose the battery to high temperatures or intense cold. For example, during the scorching days of summer, you should not put it in a car to expose it to the hot sun.ant or take it to an air-conditioned room and place it; in a place where the air conditioner blows directly. When charging, it is normal for the battery to be a little warm, but it should not withstand the “suffering” of high temperatures. To prevent this from happening, it is best to charge at room temperature and not cover anything.
11. The nickel-cadmium (N iCd) battery must be completely discharged before recharging, and the battery must be fully charged after recharging.
12． If the battery has been left unused for too long, it is best to contact the maintenance department to request lifetime treatment of the battery. You can also use a DC voltage regulator yourself to adjust the voltage to 5~6V and the current. at 500 ~ 600 mA and connect the battery in reverse. Note that you can release it as soon as you touch it and repeat up to three times. After this process,use the original charger to charge during the “adjustment period”.
13． The longer the charging time, the better. For batteries without protection circuits, charging should be stopped once they are fully charged, otherwise battery performance will be affected by heat or overheating.
14. Lithium-ion batteries must use a special charger, otherwise they may not reach saturation and affect their performance. After charging, avoid leaving it on the charger for more than 12 hours, and separate the battery when not in use for a long time.
Is graphene battery or lithium battery better?
1. First, attach the battery diaphragm, apply air pressure to one side of the diaphragm, measure the air pressure drop and used time, and detect the air permeability of the diaphragm.
2. OfSecond, when attaching the lithium battery separator, apply a certain air pressure to one side of the separator.
3. Finally, the air pressure will gradually decrease until it is equal to atmospheric pressure.
01 Graphene batteries and lithium batteries each have their own advantages and disadvantages. From the perspective of R&D technology maturity, manufacturing costs and market economic benefits, lithium batteries have more advantages than graphene batteries. But in terms of energy storage, long life, charging speed, etc., graphene batteries are better. Graphene is a relatively high-end scientific research product in many fields at home and abroad, and a lot of manpower, material resources and practices have been invested in research and Development. The extraction processon graphene is tedious and the extraction cost is very high. It is not yet fully trained for battery use. There is a long way from the laboratory to commercial application. Nowadays, the dominant battery in the market is still lithium battery. Which is better, graphene battery or lithium battery? It is necessary to compare the advantages and disadvantages of their own hardware characteristics and applications in the market to distinguish them under which circumstances. Advantages of graphene batteries: 1. The energy storage capacity is three times that of the best products currently on the market. The specific energy value of a lithium battery is 180Wh/kg, while a graphite battery's specific energy exceeds 600whkg. An electric vehicle powered by this battery can travel up to 1,000 kmilometers and its charging time is less than 8 minutes. 2. Long life. Graphene has greater advantages than traditional batteries in terms of lifespan, its lifespan is twice that of lithium batteries and four times that of hydrogen batteries. 3. Lightweight. Graphene's properties help reduce the weight of the battery by half that of a traditional battery, which can increase the efficiency of machines that transport the battery. Disadvantages of graphene batteries: 1. At present, graphene has not yet reached the practical stage, and there is still a long way to go before mass production. 2. These graphene batteries on the market are not pure graphene batteries. They are simply doped with certain graphene-related technologies on the basis of lithium batteries, which provides a slight improvement in performance. little. Moreovers, the cost of graphene is very high, as is its manufacturing process. The manufacturing process for graphene batteries is not yet sufficiently mature. It is currently only in the laboratory stage and cannot reach mass production. According to graphene analysis, lithium batteries have more advantages than graphene batteries in terms of research and development technology maturity, manufacturing costs and market economic benefits . But in terms of energy storage, long life, charging speed, etc., graphene batteries are better.
