## What to look at before buying the TB442

- The TB442 needs 207 × 175 × 175 mm of space (European case size LB1): measure it with the hold-down clamp in place.
- The TB442 has the positive terminal on the right: compare it with your current battery.
- Your current battery should say about 44 Ah; a little more is also fine.
- Cold cranking: 420 A (EN), equal to or higher than the original.
- If your car has Start-Stop, the TB442 is not the right one: it needs an EFB or an AGM.

## Inside the TB442: lead-acid technology

Inside, the TB442 is classic lead-acid: liquid electrolyte and lead plates. If the TB442 is left discharged for weeks it sulphates: a maintenance charger prevents this.
