have an 05 tl still on its original battery but its starting to fade. my question is what is the correct battery size for my car. the oem battery says its a 24f but when i research batteries online i always get back a size of group 35. just wanna make sure i get proper fitment. thanks in advance.

 

I was in the same boat last fall. I picked up a group 35 at Costco (their code 3) for something like $65 after core deposit refund. So far, so good. If you are plain stock (no large aftermarket electronics) and don't have to have a particular brand you'll be fine.
