Group 35 battery size

Same box, other group numbers

• Group 25: 9.06 x 6.89 x 8.86 in, different terminal layout (BCI figure 10, not 11).

Same box does not mean same battery: if the terminals are on the other side, the cables may not reach.

Before you buy a group 35 battery

• Read the group number on the label of the battery in your car, or in the owner's manual: it should say 35.
• 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.
• 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 35 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.
