With the increasing use of laptops, the maintenance of laptop lithium-ion batteries has also attracted attention. Many people are unfamiliar with the lithium-ion batteries in laptops and do not know how to use and maintain them. Below, we will explain how to properly charge a laptop lithium-ion battery.
Avoid letting the battery completely drain before recharging, as this puts significant stress on the battery and can cause damage. A better approach is to charge when the battery level is around 20-30%. In fact, laptop lithium-ion batteries have a limited number of times they can be completely drained and recharged; fully draining them before recharging will significantly shorten their lifespan. Additionally, the battery should be charged in a relatively dry environment, and heat should be a major enemy of battery health.
The use of mobile phone batteries is different from that of laptop batteries. Many people may judge based on their own experience with mobile phone batteries that laptop lithium-ion batteries should also be completely drained before recharging, but this idea is incorrect.
Should laptop batteries be stored fully discharged or fully charged? Storing a fully discharged battery for an extended period can cause the cells to lose activity and may even trigger the control circuit's self-locking mechanism, rendering it unusable. Storing a fully charged battery for an extended period poses safety risks. The ideal storage method is to use the battery down to about 40% and then store it in a cool, dry place at approximately 20 degrees Celsius. Ideally, the battery should be used once a month to ensure it's in good condition without completely draining and damaging it.
