Can you charge an 11 volt laptop battery with a 12 volt power supply?
user
Probably. Electronics can often survive double the voltage of what they are rated for, but it is not recommended!

Can anything bad happen to the laptop?
user
Yes, charging a battery with a higher voltage may lead to several problems, such as overcharging, short-circuits, reduced battery life, swelling, leakage, and in severe cases, even explosions.
