There is no difference in a truck battery or a car battery unless you are talking about a semi. As long as the battery fits, it the same voltage, and has sufficient CCA (cold cranking amps) it will work in a truck or car.
Car battery life is determined by the model of the battery, not the car or truck in which it operates.
Yes
yes
No, at most it is damaging property.
Car battery charges can check the damage done to the actual battery but to the entire car is another story
no. It can overheat the battery, damaging it.Here is a separate answer: I just charged a 12v car battery using a 110v DC Welder set on 10 amps, and putting out 50v. I had to check the battery every 30 minutes for overheating, which it did not. I know this is not recommended as I risk damaging the car's electrical system and the battery, but I was in a pinch.I only charged it for 1.5 hours, and there is a substantial risk that the battery will explode. I disconnected the terminals at the welder to avoid igniting the hydrogen that forms around the battery during the process.Other risks include overcharging the battery because chargers designed for 12v drop to a trickle when the battery is fully charged, avoiding damage to the battery.
Anytime you make modifications to the a vehicle from how the manufacturer orginally made the car you have the possibility of damaging it.
Yes, putting a sticker on someone's car without their permission can be considered vandalism, as it involves defacing or damaging someone else's property.
Putting a DVD player in your car will have a mild, but unsubstantial effect on your battery's voltage output.
Short answer: Yes - MaybeLong answer: Yes, if that batter will fit in the car's battery tray, and has the posts or side terminals in the correct place. additionally you will want to ensure that it is a 12volt battery and not a 18 or 24 volt battery (depending on what you mean by truck). You will also want to look at both batteries and see if you can see the CCA # this is the Cold Cranking Amps, make sure that the "truck battery" is equal or exceeds the Car battery.
There is no fool proof way. Get a new battery if putting it on a slow charger does not work.
Check fuses.
