Group size, terminal side, and whether the car needs an AGM battery.
Buying advice
Match the group size and terminal layout on the battery already in the car. Start-stop cars need AGM or EFB. Many BMWs must have the new battery registered with a scan tool before they will charge it.
Check before you buy: trims and mid-year changes can affect fit. Enter your VIN or registration at the retailer to confirm, and compare the OEM number on your old part.

Commonly listed group size for the E210 Corolla. Read the label on the battery in the car before ordering — CCA and terminal side still have to match.
