## Exide AGM12-5 vs AGM12-4 and ETX4L-BS: which one to choose?

How the AGM12-5 compares with Exide batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide AGM12-5 (this one) | 4 Ah | 70 A | 115 × 70 × 105 | right | 1.8 kg |
| Exide AGM12-4 | 3 Ah | 50 A | 115 × 70 × 85 | right | 1.2 kg |
| Exide ETX4L-BS | 3 Ah | 50 A | 115 × 70 × 85 | right | 1.5 kg |

- Exide AGM12-4: 1 Ah less, 20 A less cranking power, a different case (115 × 70 × 85 mm).
- Exide ETX4L-BS: 1 Ah less, 20 A less cranking power, a different case (115 × 70 × 85 mm).

## Check this before ordering the Exide AGM12-5

- Length, width and height of the AGM12-5: 115 × 70 × 105 mm.
- Polarity of the AGM12-5: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- With 4 Ah, the AGM12-5 replaces an original battery of that capacity or slightly less.
- Check the EN amps on your battery: if it says 70 A or less, the AGM12-5 covers your engine.

## Frequently asked questions about the Exide AGM12-5

### AGM12-5 or AGM12-4: which one suits me?

Compared with the AGM12-5, the Exide AGM12-4 has 1 Ah less and 20 A less cranking power. The AGM12-5 cranks harder; the AGM12-4 is only a good option if your original battery says 50 A or less. Mind the space: the AGM12-4 measures 115 × 70 × 85 mm.

### How much does the Exide AGM12-5 weigh?
