BCI battery group
Group 24R battery size
A BCI group 24R battery is at most 260 mm long, 173 mm wide and 229 mm tall (10.24 × 6.81 × 9.02 in), according to the Battery Council International group chart.
| Maximum size | 260 × 173 × 229 mm |
|---|---|
| In inches | 10.24 × 6.81 × 9.02 |
| Terminal types | A and A2 |
| Polarity | Reversed (R): positive terminal on the opposite side from the base group |
| Cold cranking amps (OE range) | 585–585 A |
| JIS equivalents | 48D26L, 55D26L, 65D26L, 75D26L, 80D26L and 110D26L (BCI best fit) |
Cars whose manuals point to group 24R
None of the owner's manuals this site has read so far print group 24R. 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 24R
To take a group 24R, the tray needs at least 260 mm (10.24 in) of length and 173 mm (6.81 in) of width inside the hold-down, and 229 mm (9.02 in) of height below the hood or any bracket, with room left for the cable ends. These are BCI maximums: a real group 24R battery can be a few millimetres smaller, never larger. Original-equipment batteries in this group were rated from 585 to 585 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 24R. 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 24R
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.
