240 at an Indy used a Interstate it has a better warranty.

If you buy a coding setup you can DIY it.(the registration and install)
If you buy the same battery at a store it runs around 160 to 180.
You should consider buying a battery tender as these cars are
battery hogs . A ctek 3300 is considered one of the the better ones.
This is really needed if you don't do much highway driving or leave the
car set for long periods you really need the battery teneder.
Also locking the car and getting the key fob away from it will cause it to go to
sleep mode faster and be less drain on the battery.
I think the replacement was a MTB92R/h8. Your original may or may not be different mine had a 92 amp hour capacity.
