Lithium-ion batteries have been widely used in digital products and new energy vehicles.
Regarding laptop batteries, mobile phone batteries, camera batteries, MP3/MP4/PSP lithium-ion batteries:
1. Regardless of whether the battery is new or not, it can be unplugged and used once fully charged. Generally, it takes 2-4 hours to fully charge. Do not charge for 8 to 12 hours or more, as that is considered overcharging, which is harmful to the battery.
2. When your phone displays a low battery warning, you should start charging it as soon as possible, rather than waiting until it's completely out of power.
3. Lithium-ion batteries do not require any special activation method; they are activated before leaving the factory. Insisting on using the widely circulated method of "activating with three 12-hour long charges for the first three times" will actually be ineffective.
In the field of new energy vehicles, current electric vehicle lithium-ion battery chargers all use a three-stage charging process: constant voltage stage, constant current stage, and trickle charging stage. The first two stages are crucial for charging. After these stages, the battery is basically fully charged, and the indicator light will turn green, indicating the start of the trickle charging stage. To protect the battery, do not disconnect the power at this time; continue charging for 1-2 hours to effectively extend battery life. However, once the light turns green, do not exceed 8 hours.
In addition, it is important to note that lithium-ion batteries should not be activated during the initial stage of new battery use. In daily use, simply charge the battery normally when it is out of power. Continuously using the battery until it is completely dead or low in power before recharging will actually affect the battery's lifespan.
In general, the initial charging time for a lithium-ion battery can be determined based on the actual battery capacity. Many people charge their lithium-ion batteries for 8 or 9 hours on the first charge, which is completely unnecessary. Charging a lithium-ion battery for an extended period does not improve the phone's durability.
Most mobile phones nowadays are smartphones with large screens and fast battery drain. Even with high-capacity lithium-ion batteries, phones need to be charged daily if used for extended periods. People whose phones drain quickly should carry a power bank or spare battery.
