How do I take care of and charge my Lenovo L21D4PE3 battery correctly?

  • If you mainly use your laptop while it’s connected to mains, you should remove your battery and only charge it every one to two months.
  • Don’t fully discharge your Lenovo L21D4PE3 battery, because this can lead to a depth discharge. Charge the battery again, when between five and seven percent of charge remain.
  • If possible charge your battery while the notebook is turned off. The optimal temperature for batteries is between 10 and 30°C, this range is usually exceeded in a powered-on notebook.
  • If you have multiple batteries for your device, rotate between them.
  • After being uncharged for a while, the Lenovo L21D4PE3 battery needs about two to three complete charge cycles to reach its full capacity again.
  • Avoid high temperatures for example due to direct sunlight or being left in a hot car. High temperatures increase the self-discharging rate.
  • Rechargeable Lithium-Ion batteries, which are found in nearly all modern electronics, have a limit of somewhere between 500 to 1000 charge cycles. However, turning your laptop on and off while plugged in is one charge cycle. This is why we recommend removing the battery when using the device plugged in for a longer time.
  • Furthermore, it would be optimal to never fully charge or discharge your L21D4PE3 battery, but rather to keep it between 20% 80% charge.

Some manufacturers integrate a L21D4PE3 battery protection function in their notebooks. This function only allows charging up to 80% capacity to prolong he lifespan of the battery.

On the contrary for many modern devices the opposite is true, it is best to keep the charge between 20% and 80%. This is due to the sensitivity of Lithium-Ion batteries to depth discharge and overcharge. However, in most devices control electronics prevent the user from making any grave mistakes. For example, Apple implements a function which charges the battery as fast as possible up to 80% but charging slows down a lot after that. This conserves the lifespan of the battery at the cost of charge time.

One thing that should be avoided though is leaving your device plugged in for many days in a row. The Lenovo L21D4PE3 battery should be discharged once in a while to move the ions inside.
