Can you charge an 11 volt laptop battery with a 12 volt power supply?
It is generally not recommended to charge a laptop battery with a power supply that has a higher voltage than what is specified for the battery. Using a 12-volt power supply to charge an 11-volt laptop battery can potentially damage the battery or the device it powers. It's best to use a power supply with the correct voltage for your laptop battery, which is usually specified on the battery itself or in the device's manual. If you're unsure, it's best to consult with a professional or manufacturer to avoid any potential harm to your device.
Assume that I do not have the funds to purchase a new - proper - power supply. Can you tell me common places I could reliably find cheap, used power supplies?
