33YDH Laptop battery tips

Newly bought notebooks, the first three charges do not need to reach 12 hours, because the current laptop batteries have a management chip that can control the charging limit, when the battery is full, it will automatically cut off the charging function, thus protecting the battery life and avoiding overcharging.

It is not necessary to discharge completely before each charge, because this deep discharge will shorten the battery life. It is recommended to charge when the remaining 10% is left. In addition, when there is still more than 30% of the battery power, it is best not to charge, because the memory effect does exist. The power management software allows you to check the battery level at any time, and the Dell Inspiron 17 7778 7779 Series come with a battery indicator that allows you to check the remaining battery even without turning it on.

When plugging in AC power (connecting the power adapter), you don't need to remove the battery

, because most laptop batteries need to be charged below 90%, and the battery naturally discharges to this capacity takes two weeks to a month, so use it every day. Notebooks don't have to worry about repeated charging and unloading, not to mention the fact that emergency power outages are more damaging to data.

If you want to store unused batteries for a long time, you need to put them in a dry, low temperature environment while maintaining 40% of the remaining power in the battery. In addition, it is best to take out the battery once a month to ensure a good storage state and service life of the battery.

Reducing the brightness of your notebook screen can extend the life of your notebook and reduce the number of times it is charged.

Use some power management tools, such as the Power Assistant on the Dell Inspiron 17 7778 7779 Series, which can even monitor the energy consumption of each component in real time through the PMC circuit, and accurately summarize the company's status to the HPclient Configuration Manager software, and optionally Turn off the specified parts to extend battery life.
