## Before ordering the DB741, check this

- Measure the space: the DB741 takes up 278 × 175 × 190 mm (European case size L3).
- Polarity of the DB741: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 74 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 680 A or less, the DB741 covers your engine.
- If your car has Start-Stop, the DB741 is not the right one: it needs an EFB or an AGM.

## What it means that the DB741 is lead-acid

Inside, the DB741 is classic lead-acid: liquid electrolyte and lead plates. If the DB741 is left discharged for weeks it sulphates: a maintenance charger prevents this.
