The battery is a lithium-ion battery. 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 the first few times. a new battery is normal. Charging is said to not require 12 hours in the first three adjustment periods. When purchasing or charging the battery, the seller will tell us that charging takes 12 hours in the first three times. ! 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 charge it naturally, which is a natural discharge after adjustment. period, charge it again, that is, recharge it again, another half hour of charging, or about two and a half hours, will be enough. The baterie usually needs about 10 charge and discharge cycles to achieve 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, and after that you can charge for 2.5 hours each time. There are two popular opinions about the first three times of charging: 1. When purchasing a machine, let it charge for more than 12 hours. 2. The second is that it is better to charge for another 1-2 hours after it is fully charged. The first method is to use nickel-metal hydride batteries in the past. Hydride batteries were used. Since metal hydride batteries have memory capabilities, it is best toe use them before rinsing the first three times, 12 hours of charging, to fully activate the battery and obtain good results. so sellers are used to it, but now it 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 overcharge protection. They start with a high current charge, then a trickle charge once full, the power supplytation 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. A battery can be charged and discharged approximately 500 times. The 2128 series battery can have a battery lifestandby for about 4 days after several charge and discharge cycles. It can therefore be used for approximately 3 years. eliminated. So just one battery is enough! Battery life is measured by the number of charging and discharging times, if the battery is charged before being exhausted, the battery life will be shortened. 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 usage time of the battery, in addition to ensuring the quality of the charger, correct charging techniques are also essential, as poor quality chargers or incorrect charging methods will affect the battery life. usage and battery life. Here are the charging tips: 1. Before the battery leaves the factory, the manufacturer has activated ited and pre-charged, 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 should 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 charge cothe battery completely. 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 charging. 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 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, it can easilyharm the service life, 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 approximately 1% of their remaining capacity each day, and lithium batteries discharge 0.2% to 0.3% of their remaining capacity each day. day. When charging the battery, try to use a dedicated outlet and do notDo not share the outlet with charger, TV and other household appliances. 9. Although it is within the network coverage area, it is no longer able to receive and make calls when turned off and charging. 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. ten. Do not expose the battery to high temperatures or intense cold. For example, in summer days, it should not be placed in a car to resist the scorching sun or in an air-conditioned room. In a place with direct air conditioning. When charging, it is normal for the battery to be a little warm, but it should not withstand the “suffering” of high temperatures.vees. 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 battery life treatment. 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 must be stopped once they are fully charged, otherwise the perfBattery life will be affected by heat or overheating. 14. Lithium-ion batteries must use a special charger, otherwise they may fail to 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.
The size, voltage and working principle of the two are different.
1. Size:
Although 18650 and AA batteries look similar, the sizes of the two are actually different: 18mm in diameter and 650mm in length. The model number of the AA battery is 14500, with a diameter of 14mm and a length of 500mm.
2. Voltage:
Lithium battery voltage is usually around 3.5-4.0V, the most common is 3.7V, while AA battery voltage is 1.5V (non-rechargeable). ) Or 1.2 V (rechargeable).
3. Principle of foOperation:
These two batteries are essentially different in terms of capacity and material, so their internal chemical reactions are completely different.
18650 lithium batteries can be divided into 18650 lithium ion batteries, 18650 lithium iron phosphate batteries and 18650 nickel metal hydride batteries; while AA batteries include nickel metal hydride rechargeable batteries, nickel cadmium rechargeable batteries and alkaline zinc. manganese batteries (referred to as “alkaline batteries”), ordinary zinc-manganese acid batteries (referred to as “ordinary batteries”), etc.
