Why leaving li-ion batteries plugged in kills them? I don't know. I didn't say that it is related to memory effect, but I have experienced it in cell phones. The only charger I would leave batteries in overnight is an IDX or similar charger. IDX has an FAQ for battery care (previous link), but they don't mention leaving them in the charger, yeah or neah.

Over time, after repetitive use of your laptop on LENOVO IdeaPad Y570d Battery power, laptop batteries do become degraded and their maximum charge decreases.

Eventually, especially if you keep your laptop computer for many years, you may find your battery doesn't hold as much charge as they used to and you may have to purchase a replacement laptop battery.
