Yes they can be installed in any car or truck that has a good battery.
If the alternator is installed incorrectly, yes, it can drain the battery.
If the remote car starter stopped working after a new battery was installed in the remote, the remote needs to be reprogrammed. If the remote starter stopped working after a new battery was installed in the vehicle, the computer might need to be reset by disconnecting the battery for a few minutes.
No, not unless you installed a 6 volt battery instead of a 12 volt battery.
It is a good quality battery. I have one installed in my Toyota that is 5 years old.
The noise is difficult to diagnose over a forum, but if the battery is charged correctly, and is hissing as you put it, the starter motor may not be working correctly, get a second opinion from a garage
Sounds like you have an exhaust leak, try starting the car on jack stands then get under the car and check the gaskets for leaks
If your question is what may be a problem with a car that you have to change the battery after a new battery was installed a month ago? Then the alternator may be suspect and or a draw from the electrical system.
aranbanoo's mum will know..
I suggest you buy a new car battery replacement in http://www.laptops-battery.co.uk/.
dead cell in the battery or something is on that is pulling power from the battery.
If the battery was charged when you installed it, you do not have to drive the car at all. If not you should charge the battery and not use the cars alternator to charge it.
