Make sure to charge it for 10-12 hours for the first three times. you won't need to use your cell phone batteries in the future. Use and protection Have you ever encountered such a situation: your mobile phone which has just been charged and is on standby turns off in an instant. This is because your cell phone's nickel-cadmium or nickel-metal hydride battery will produce a memory effect if it is recharged without being completely discharged several times, making the battery usable for increasingly shorter times between charges, and finally the battery will accept the charge. The battery capacity is damaged, resulting in the phenomenon that it is full when charged and exhausted when used. Even if the battery is used carefully, it is normal for its function to gradually decrease.ssively after a few years, which is why any rechargeable battery has its lifespan. The lifespan of NiCd batteries varies depending on the method of charging and discharging. Under normal circumstances, the battery can be used for more than 500 charge and discharge cycles, and the capacity after one year is about 75% of the maximum value. Currently, the most popular cell phone batteries on the market include high-efficiency lithium batteries and nickel metal hydride batteries. Nickel-metal hydride batteries have a high capacity and a higher discharge rate. After recharging, the battery capacity can be restored and is beneficial to the environment. High-efficiency lithium batteries, unlike other rechargeable batteries, do not lose capacity and have the characteristics of small size, light weight, no memory effect, low rateextremely low self-discharge and long life. The charging time of lithium batteries should not exceed the required 5-7 hours, and the charging time of nickel-cadmium batteries and nickel-metal hydride batteries should not exceed 24 hours. Battery life depends on the type of battery purchased. The standby time of lithium batteries can generally reach more than 50 hours, and the continuous call state can reach 4-7 hours. Nickel-cadmium battery and nickel-metal hydride battery can last more than 20 hours in standby state and can last 1-2 hours in continuous calling state. Nickel cadmium batteries and nickel metal hydride batteries should be fully charged before use and try to avoid recharging the batteries before a low voltage alarm occurs. The way to avoid the memory effect is to completely discharge the battery once a week,then recharge it. It would be better if this was done every time. The easiest way to discharge is to leave the handset on until the battery runs out and the phone turns off automatically. Battery contact points should also be cleaned frequently. You can use a pencil eraser to scrub the contact points with good results. Never place metallic conductors on the battery. A bunch of keys in the bag can cause a short circuit and damage the battery. Fourteen Must-Have Tips for Charging a Cell Phone Battery If you want 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 all affect the battery's usage time and lifespan. Here are the tipsThey are compiled by the author:
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 mobile phone battery is lithium ion, the first 3 to 5 charges are generally called the adjustment period and should be charged for more than 14 hours to ensure sufficient charge.Activate 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 smart fast chargersAutomated nts 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 and follow the instructions,otherwise the battery will be damaged or even dangerous.
6. Many users often leave their cell phones on while charging. In fact, it can easily harm the lifespan of the mobile phone, because during the charging process, the circuit board of the mobile phone heats up at that time. external call, instant reflux may occur. Electric current can damage the internal parts of the phone.
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 mobile phone is turned off for more than 7 days, the mobile phone battery should be completely discharged and fully charged before use.
8． Cell phone batteries all discharge automatically. When not in use, batteries nickel-metal hydride batteries discharge to about 1% of their remaining capacity each day, and lithium batteries discharge to 0.2% ~ 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 the phone is within the network coverage area, it is no longer able to receive and make calls when turned off and charging. At this time, you can use the missed call forwarding function of the mobile phone to transfer the mobile phone to the landline around you to avoid incoming calls from being lost. This method is also applicable when the mobile phone is not within network coverage. area where the signal is weak and cannot be connected temporarily.
10． Do not expose the battery to high temperatures or extreme cold.tense. For example, during the dog days of summer, you should not leave your phone in a car to expose it to the scorching sun or take it to an air-conditioned room and place; 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's best to charge at room temperature and not cover the phone with 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 cell phone battery has been left unused for too long, it is best to contact the cell phone maintenance department to request battery reconditioning. You can also use a voltage regulator yourselfDC ion to adjust the voltage to 5 ~ 6 V. and current to 500 ~ 600 mA and connect the battery in reverse. Note, touch and release, repeat at mostThree times is enough. After this treatment, 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 from the cell phone when not using it for a long time.
