## Before ordering the DC904, check this

- Measure the space: the DC904 takes up 306 × 173 × 222 mm (European case size D31).
- The DC904 has the positive terminal on the right: compare it with your current battery.
- Capacity of the DC904: 90 Ah; the same as your current battery or slightly more is fine.
- Check the EN amps on your battery: if it says 680 A or less, the DC904 covers your engine.
- If your car has Start-Stop, the DC904 is not the right one: it needs an EFB or an AGM.
