BCI battery group
Group 93 battery size
A BCI group 93 battery is at most 353 mm long, 175 mm wide and 175 mm tall (13.9 × 6.89 × 6.89 in), according to the Battery Council International group chart.
| Maximum size | 353 × 175 × 175 mm |
|---|---|
| In inches | 13.9 × 6.89 × 6.89 |
| Terminal types | A1 and A2 |
| Polarity | Standard layout for this group |
| Cold cranking amps (OE range) | 600–800 A |
| DIN / EN equivalent | T8 / LBN5 (BCI best fit) |
Cars whose manuals point to group 93
None of the owner's manuals this site has read so far print group 93. 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 93
To take a group 93, the tray needs at least 353 mm (13.9 in) of length and 175 mm (6.89 in) of width inside the hold-down, and 175 mm (6.89 in) of height below the hood or any bracket, with room left for the cable ends. These are BCI maximums: a real group 93 battery can be a few millimetres smaller, never larger. Original-equipment batteries in this group were rated from 600 to 800 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 93. 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 93
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.
