## What it means that the SD-53.0 is lead-acid

- If your car has Start-Stop, the SD-53.0 is not the right one: it needs an EFB or an AGM.
- Cold cranking: 500 A (EN), equal to or higher than the original.
- Your current battery should say about 53 Ah; a little more is also fine.
- With the terminals facing you, the positive terminal of the SD-53.0 is on the right.
- The SD-53.0 needs 242 × 175 × 175 mm of space (European case size LB2): measure it with the hold-down clamp in place.
