There's no reason to remove the battery, as it won't charge anymore, or be used as it reaches 100%. Laptops, cell phones, etc are all smart enough to not over-charge the battery. I am absolutely convinced people overthink their battery usage. At most, I'd say to drain the battery down every so often, and then charge it back up fully, but even that is becoming less and less important, as the batteries don't usually exhibit memory functions anymore. I'm not sure why you'd think the battery would become damanged when it was plugged in. If so, most business users would damage their batteries all the time.
