- Deta DK111: 4 Ah less, 50 A less cranking power, a different case (150 × 90 × 130 mm).

## What it means that the DK151 is AGM

The DK151 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. Being sealed, the DK151 can be fitted in the boot or under a seat with no risk of spills.

## What to look at before buying the DK151

- Length, width and height of the DK151: 150 × 90 × 145 mm.
- Polarity of the DK151: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 15 Ah; a little more is also fine.
- Cold cranking: 200 A (EN), equal to or higher than the original.
