## Description

## The Exide EK720 at a glance

The Exide EK720 is a battery for cars with Start-Stop: it withstands many more starting and partial-discharge cycles than a conventional battery and powers the electronics every time the engine stops at the lights.

## Before ordering the EK720, check this

- Length, width and height of the EK720: 278 × 175 × 190 mm (European case size L3).
- The EK720 has the positive terminal on the right: compare it with your current battery.
- Your current battery should say about 72 Ah; a little more is also fine.
- Cold cranking: 760 A (EN), equal to or higher than the original.
- The EK720 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.

## What it means that the EK720 is AGM

The EK720 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.

## Frequently asked questions about the Exide EK720

### EK720 or EK620: which one suits me?

Compared with the EK720, the Exide EK620 has 10 Ah less and 80 A less cranking power. The EK720 cranks harder; the EK620 is only a good option if your original battery says 680 A or less. Mind the space: the EK620 measures 242 × 175 × 190 mm.

### Can the Exide EK720 be used in a car with Start-Stop?

Yes. As an AGM battery, the EK720 handles automatic engine stop and brake energy recovery, and it can replace an EFB of the same size.

### How much does the Exide EK720 weigh?

20.6 kg, with 72 Ah of capacity. For reference, the Exide EK620 (62 Ah) weighs 17.9 kg.

### Which battery is equivalent to the Exide EK720?

Only other AGM batteries with its dimensions and polarity: Fulmen FK720, Tudor TK720 and Deta DK720. Neither an EFB nor a conventional battery replaces the EK720. Its Bosch equivalent is the Bosch S5 A08, the same as for the Varta A7. Bosch is not part of our catalogue; we list it so you can compare.

### What case size is the Exide EK720?

Case size L3: 278 × 175 × 190 mm. The EK720 fits any standard L3 battery tray such as the Fulmen FK720.

### Which side is the positive terminal on the Exide EK720?

On the EK720, the positive terminal is on the right with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.

### Which charger does the Exide EK720 need?

A charger with an AGM mode that limits voltage to about 14.4-14.7 V. Never an old unregulated charger: overcharging dries out an AGM beyond repair.
