For example I leave my battery in since I don't want my machine to reboot if the AC power drops out.
Another owner may want to "save the battery" and will live with the reboot.
-> So isn't the right question "What do you want?"
Hi, I have a possible buyer. I want to give him the correct information about the battery. It takes about 4 hours to charge the battery when it's not in use. Should I tell the buyer to disconnect the battery after using it or keep it plugged in and charged?
