With lithium ion batteries this actually should not kill them, the batteries have built in items to prevent them from charging in a range. Bascially even if you have your laptop plugged in 24/7 it should only charge when the battery drops below a certain voltage, if its not pulling current from the battery the voltage will not drop.
Most lithium ion-batteries have 200-400 charge cycles, that means if it has to charge every day it will only last a year.
The reason for batteries exploding is due to the hotter processors used in newer computers, and the relation to the battery, which if it reaches a certain temperature insulating material can melt and cuase a short. Every case so far the system was on and not able to get ventilation.
The odds of dying in a car accident is 1 in 5000, the odds of having your laptop explode so far would be 1 in 5,000,000. (6 laptops blew up, 30 million dell laptops in use right now) If it did blow up you could have one heck of a lawsuit.
However this is a design flaw using the wrong types of materials.
Ever leave your laptop on a bed turned on? it will get quite warm if the intake fans are on the bottom and unable to get air.
Another issue causing heat is when the fan fails, then the laptop will shut down but not before it gets extremely hot.
