If there is any charge left in the battery, connecting it the wrong way should blow the fuse in the charger before any damage is done.
Motors, heaters and lamps will not be affected.
Electronics, such as radios, cds, and engine management systems however, do not like reverse polarity and will blow the semiconductors inside, if reverse connected.
Most properly designed and constructed car electronics, have protection on their power supply lines, to stop devastating destruction caused by reverse polarity. This is usually a reverse connected diode across the power input lines.
Connected properly, the diode does not conduct and has no effect. Conncted in reverse and the diode will conduct, putting a short across the line and hopefully blowing a fuse to protect it. (crowbar protection).
So, you may get away with it. But it is not advised.
It may of may not.
Connecting a battery charger backwards to a battery will likely kill the battery, depending on how long the power is attached.
Yes, an 18 volt charger can damage a 14 volt battery. This is because the wattage for the battery needs to be equal to the wattage of the charger.

no, but it will damage the battery.
Sorry, but that is not likely to work. Both the voltage and amperage provided by a charger for a laptop battery will not be correct for a car battery. It is likely that you will damage the charger.
No
Yes
No, the battery will be overcharged and battery damage will occur if it is done.
No you should not do that. It will damage the battery and the battery will explode.
A car battery charger is too powerful for that size battery and will damage it. Check out this charger http://www.replacementupsbattery.com/Product_pages/wka12v1000.html Hope that helps!
"Sparking" When Connecting a BatteryWhen sparks occur on connecting a battery [IF the cables are connected to the proper terminals and in the proper order] is an indication that some of the electricity using devices [clock, computers, etc.] in the vehicle's electrical system are drawing electrical current.IF the battery cables are being connected properly, this sparking is normal, causes no damage, and is nothing to be concerned about.
NO, you can damage it.
