How do I take care of and charge my HP N39857-005 battery correctly?

If you mainly use your laptop while it's connected to mains, you should remove your HP N39857-005 battery and only charge it every one to two months.
Don't fully discharge your 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 HP N39857-005 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 N39857-005 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 HP N39857-005 battery when using the device plugged in for a longer time.
Furthermore, it would be optimal to never fully charge or discharge your N39857-005 battery, but rather to keep it between 20% 80% charge.

Some manufacturers integrate a N39857-005 battery protection function in their notebooks. This function only allows charging up to 80% capacity to prolong he lifespan of the battery.
