## Exide EK500 vs EK454: differences

The real differences between the EK500 and the closest Exide models:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide EK500 (this one) | 50 Ah | 570 A | 207 × 175 × 190 | right | 15 kg |
| Exide EK454 | 45 Ah | 380 A | 237 × 127 × 227 | right | 13.5 kg |

- Exide EK454: 5 Ah less, 190 A less cranking power, a different case (237 × 127 × 227 mm).

## What it means that the EK500 is AGM

The EK500 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.

## Before ordering the EK500, check this

- Measure the space: the EK500 takes up 207 × 175 × 190 mm (European case size L1).
- Polarity of the EK500: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Capacity of the EK500: 50 Ah; the same as your current battery or slightly more is fine.
- Check the EN amps on your battery: if it says 570 A or less, the EK500 covers your engine.
