What is a cheap battery i can buy for my X? I don't want anything heavy duty or light weight. I am selling the car and i just a battery that will start and last for the new owner.

 

Any battery that fits will likely start the car.

 

Any battery will work. I would just get whatever is local.

 

Doesn't the battery have to be sealed since it is in the engine bay?

 

I think you mean trunk, and yes. Either sealed (AGM preferably) or OEM with the special venting. Basically any AGM battery will start the car. You can check Crutchfield or Sonic Electronix for batteries. AGM batteries can even be mounted on their side.

I'll be swapping my battery soonish (a week or so) and could sell you my OEM battery for cheap.

 

A Lightweight AGM battery is available at Pep Boys, the 51 group size should fit 4 year free replacement guarantee as well.
