## Quick description

## Description

## Who the Exide EK620 is for

The Exide EK620 is designed for automatic engine stop and regenerative braking. In a Start-Stop car, the EK620 keeps the radio, climate control and lights running with the engine off without losing capacity.
At 62 Ah it is the usual size for compact diesels and mid-size petrol saloons. The EK620 belongs to the Exide EXIDE AGM range. [See all Exide batteries](https://bateriasonline.es/en/exide-batteries)

## What it means that the EK620 is AGM

Inside, the EK620 has glass fibre separators (AGM) that hold the electrolyte. It is fitted in cars with advanced Start-Stop and in deep-cycle equipment.

## What to look at before buying the EK620

- The EK620 is AGM: it replaces an AGM or an EFB of the same size. You can swap an EFB for an AGM, but not an AGM for an EFB.
- The EK620 delivers 680 A cold cranking (EN standard); do not go below what your original battery states.
- Capacity of the EK620: 62 Ah; the same as your current battery or slightly more is fine.
- Polarity of the EK620: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- The EK620 needs 242 × 175 × 190 mm of space (European case size L2): measure it with the hold-down clamp in place.
