"Left" and "right" can be the same thing, depending on if the posts are next to you or on the other side. The way I used to remember the post layout for my Chrysler vehicles is "I need this battery right away". While standing in front of the battery, or holding it in front of me, the posts are "away" from me, meaning on the far side, then the positive post is on the right, hence, "right away".
All battery manufacturers offer their batteries with both post layouts. For many years, Chrysler, GM, and most other car manufacturers used the same standard layout. Only Ford was the oddball with the posts reversed. Batteries were sold by group size, like "24" or "27", and batteries for Fords were labeled "24F" or "27F".
Today there is no standard or common size, post layout, or mounting method. There's too many variations to put one of each style on display. The easiest way to get the right battery is to look on the charts in the stores, or ask one of the salespeople. That will insure the new battery will fit in the space provided, will mount solidly to prevent vibration and movement, and the posts will be in the right locations.
You'll also want to compare the "cold cranking amps" for your old and new batteries. New vehicles typically come with batteries with more than enough power for that vehicle's needs, but not much extra. Most replacement batteries will advertise more cold cranking amps, but you pay more for that extra power that you are likely to never need. It's sufficient too buy a new battery that has the same cold cranking amps, or has just a little more.
