Before you buy a group 140R battery

• Read the group number on the label of the battery in your car, or in the owner's manual: it should say 140R.
• The "R" means the terminals are reversed compared with the same number without R: the positive post is on the other side.
• Choose cold cranking amps (CCA) at least as high as the original, especially for cold winters.
• Measure your battery tray and the room above it, then compare with the size printed for the exact battery you pick, not only with the group number.
• Group 140R 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.
