1st you need to find & buy the proper battery size for your Toyota Corolla which you can find good info on the Toyota website. At the same time please bear in mind that there are only 3 battery manufacturers in the entire USA -- I recommend either Costco Wholesale, Walmart or like BJ's Wholesale which sells Exide.
Besides (i) price the other 2 factors distinguishing each battery are: (i) cold cranking amps (ii) free replacement battery which is normally 30 or 36 months on a 84 to 100 month battery.
Again the Toyota website besides telling an owner what is the appropriate Toyota's manufacturer's battery size has step-by-step instructions and just be sure you wear old clothes and take your time once you have all the tools in front of you.
Hope the Above Info Helps!
