1 . Should I Remove the Laptop Battery For A Desktop Replacement Laptop?
Q: I have a laptop at home which I use as a desktop replacement. As such, 99% of the time the laptop is being used it is plugged in. I wonder if I should remove the laptop battery so that it is not permanently being charged, or does the laptop cut off the current to the battery once it is fully charged? I do unplug the laptop when I turn it off.
A: When using a laptop as a desktop replacement, the battery should not be left in for long periods of time. The laptop will over time discharge the battery. Remove the laptop battery - making sure that it is charged to 40% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it.

2. How long does it take for a laptop battery to charge? Its new, I want to fully charge it.
For your first use, you must fully drain the laptop battery until the laptop goes into hibernation. After that plug in your charger and allow it charge for 12 hours or depending on what the technician has told you. 12 hours is the max and you can use it while charging. I'm not saying it would take 12 hours to charge rather it is the first charge to really awaken the ions after a long time. It's good to charge new Compaq presario v4000 laptop battery for three times at first. After that it will take less than 2 hours to fully charge your laptop battery.
This is recommended so that the laptop battery will heat up for the time allowing ions to reawaken.
