No, the Nintendo DS lite charger is not the same as the Nintendo DSi charger
If it is an automatic charger let it charge until the charger shuts off.
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.
Yes.
The Samsung has a special car charger built just for it, that will work great while traveling.
It's the same car so it will work as long as you make some changes like motor mounts, tranny exchange, and you will need the wiring harness and computer off the donor car.
they work off the engine vacuum through hoses.
If the battery has a defective cell it might not allow the car to start with a charger. Have the battery tested.
None, since they are wired to the car.
Charger.
