1. You need to pay attention when using the Macbook for the first time. It is recommended to fully charge before use. The official explanation is: "When you use your newly bought portable computer for the first time, remember to fully charge it, and then run the software update to ensure that your computer is equipped with the latest software."
2. On the issue of complete charge and discharge cycle, a charge cycle refers to using up all the electricity of the battery, but it is not the same as charging once. For example, you can listen to the iPod for several hours every day, use only half of the power and then fully charge it. If you are still like this the next day, it can only be counted as one charging cycle, not two, so it may take you several days to complete a cycle.
3. Whether the battery must be fully charged at one time and then used for cleaning and charging. The charging density of lithium-ion batteries is higher than that of nickel-cadmium or nickel-hydrogen batteries. Because lithium is the lightest metal, it means that its battery is lighter and has a longer battery life. You can charge lithium-ion batteries at any time, unlike Ni-MH batteries or Ni-Cd batteries, which need to be fully discharged or charged to achieve the best performance. Over time, crystals will be formed on the electrodes of nickel batteries, making the batteries unable to be fully charged. At this time, a complicated and complete discharge procedure must be carried out.
4. Laptops will be idle for more than half a year. Take out the battery and keep 50% charge. If the storage capacity is zero, the battery will not be able to withstand any charging due to overdischarge. On the contrary, if a fully charged battery is stored for a long time, it will lose part of the battery capacity, thus shortening the battery life. Please store the removed battery at a suitable temperature.
5. Temperature: The optimal temperature of the battery is 22 degrees, which is generally controlled at 10-35 degrees. If it is lower or higher than this temperature, the battery will be damaged.
6. Keeping the lithium-ion battery properly charged and discharged can prolong the battery life. Keeping the charge of lithium-ion battery at 10%~90% is beneficial to protect the battery. This means that it is not necessary to reach the maximum value when charging the batteries of digital products such as mobile phones and notebook computers.
7. Digital products equipped with lithium-ion batteries are exposed to sunlight or stored in high-temperature cars. It is best to turn off these products, because if the working temperature exceeds 60 degrees Celsius, lithium-ion batteries will accelerate aging. The charging temperature range of lithium battery is 0~45 degrees Celsius, and the discharging temperature range of lithium battery is 0~60 degrees Celsius.
8. If the mobile phone battery needs to be recharged every day, the reason may be that the battery is defective or should be "retired". For the laptop owner, if the plug is inserted for a long time, it is best to take out the battery (the high heat generated by the computer during use is not good for the laptop battery).
9. Under normal circumstances, 50% of the electricity is most conducive to the storage of lithium-ion batteries.
