BCI battery group
Group 58R battery size
A BCI group 58R battery is at most 255 mm long, 183 mm wide and 177 mm tall (10.04 × 7.2 × 6.97 in), according to the Battery Council International group chart.
| Maximum size | 255 × 183 × 177 mm |
|---|---|
| In inches | 10.04 × 7.2 × 6.97 |
| Terminal types | A |
| Polarity | Reversed (R): positive terminal on the opposite side from the base group |
| Cold cranking amps (OE range) | 540–580 A |
Cars whose manuals point to group 58R
None of the owner's manuals this site has read so far print group 58R. Most Japanese and Korean makers print a case size or capacity instead of a BCI group, so the battery label on the car is the better guide.
Measuring for a group 58R
To take a group 58R, the tray needs at least 255 mm (10.04 in) of length and 183 mm (7.2 in) of width inside the hold-down, and 177 mm (6.97 in) of height below the hood or any bracket, with room left for the cable ends. These are BCI maximums: a real group 58R battery can be a few millimetres smaller, never larger. Original-equipment batteries in this group were rated from 540 to 580 cold cranking amps, so the right rating depends on the car; match or exceed the rating on the battery you are replacing.

Positive numbers mean the other group is bigger than group 58R. A bigger case only fits if your tray and hold-down have that much spare room; measure inside the hold-down frame, not the old battery.
Fitting a group 58R
The group sets the case size, terminal position and hold-down. A battery from another group can only replace it when the length, width and height all fit the tray and the terminals land on the same sides. No other passenger-car group in the BCI chart has exactly the same case size and polarity. Use the tray fit checker to list every group that fits a measured space.
