Should the battery be removed if the laptop well be idle for several months??
Welcome to the community
If you will not use your laptop for extended periods of time, you can remove the battery from the laptop. Make sure you will place the battery in a well ventilated place. Make sure it will not be exposed to heat or high temperatures, since the battery's worst enemy is the heat. Hope this helps.

It is always advisable for any electronic component to remove the batteries if the device is not going to be used for a long time. For your computer, make sure to turn it off and remove the AC Adaptor and then remove the battery and make sure to store it in a cool and dry place away from direct sun light.
