## Exide ET550 vs EN750 and EP600

How the ET550 compares with Exide batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide ET550 (this one) | 80 Ah | 600 A | 278 × 175 × 190 | right | 20.7 kg |
| Exide EN750 | 74 Ah | 680 A | 278 × 175 × 190 | right | 16.7 kg |
| Exide EP600 | 70 Ah | 760 A | 278 × 175 × 190 | right | 20.6 kg |

- Exide EN750: 6 Ah less, 80 A more cranking power, the same L3 case.
- Exide EP600: 10 Ah less, 160 A more cranking power, the same L3 case, AGM technology.

## What it means that the ET550 is lead-acid

Inside, the ET550 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.

## Before ordering the ET550, check this

- Length, width and height of the ET550: 278 × 175 × 190 mm (European case size L3).
- Polarity of the ET550: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Your current battery should say about 80 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 600 A or less, the ET550 covers your engine.

20.7 kg, with 80 Ah of capacity. For reference, the Exide EN750 (74 Ah) weighs 16.7 kg.

### What case size is the Exide ET550?

Case size L3: 278 × 175 × 190 mm. The ET550 fits any standard L3 battery tray.

### Which side is the positive terminal on the Exide ET550?

On the ET550, 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.
