The battery in my car is fucked and needs to be replaced. How easy is it to change it yourself? I haven't done much stuff on cars but I'm not afraid of DIY stuff.
The battery looks like it is very accessible and that all it takes is to unscrew a few bolts.
At some auto parts stores the employees will help you replace the battery. I wouldn't know without seeing your car, but if it looks easy it probably is. Just make sure the new one is fully secured.
