No other group in the BCI table comes within 10 mm (0.4 in) of group 49 on all three sides: look for group 49 itself.
Before you buy a group 49 battery
- Read the group number on the label of the battery in your car, or in the owner's manual: it should say 49.
- A group with an "R" after the number has its terminals reversed: do not swap one for the other without checking where your cables reach.
- Choose cold cranking amps (CCA) at least as high as the original, especially for cold winters.
- Group 49 has top posts: the new battery must match, and the hold-down must fit the box.
- Most stores take the old battery back for recycling, often against a core charge.
