## Exide EB4L-B vs AGM12-5, AGM12-4 and ETX4L-BS: differences

Torn between the EB4L-B and another similar Exide? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide EB4L-B (this one) | 4 Ah | 50 A | 120 × 70 × 95 | right | 1.6 kg |
| Exide AGM12-5 | 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 ETX5L-BS | 4 Ah | 70 A | 115 × 70 × 105 | right | 1.9 kg |

- Exide AGM12-5: the same capacity, 20 A more cranking power, a different case (115 × 70 × 105 mm), AGM technology.
- Exide AGM12-4: 1 Ah less, the same cranking power, a different height (85 mm instead of 95 mm), AGM technology. It is the option if your battery tray cannot take the 95 mm height of the EB4L-B.
- Exide ETX4L-BS: 1 Ah less, the same cranking power, a different height (85 mm instead of 95 mm), AGM technology. It is the option if your battery tray cannot take the 95 mm height of the EB4L-B.
- Exide ETX5L-BS: the same capacity, 20 A more cranking power, a different case (115 × 70 × 105 mm), AGM technology.

## What to look at before buying the EB4L-B

- The EB4L-B needs 120 × 70 × 95 mm of space: measure it with the hold-down clamp in place.
- The EB4L-B has the positive terminal on the right: compare it with your current battery.
- Capacity of the EB4L-B: 4 Ah; the same as your current battery or slightly more is fine.
- Cold cranking: 50 A (EN), equal to or higher than the original.

## Frequently asked questions about the Exide EB4L-B

### EB4L-B or AGM12-5: which one suits me?

Compared with the EB4L-B, the Exide AGM12-5 has 20 A more cranking power and AGM technology. If your current battery says 70 A or more, choose the AGM12-5; if it says 50 A or less, the EB4L-B is enough. Mind the space: the AGM12-5 measures 115 × 70 × 105 mm.

### Exide EB4L-B or AGM12-4/ETX4L-BS: what changes?

Mainly the height: the EB4L-B is 95 mm tall and the Exide AGM12-4 85 mm, with the same length and width. In capacity and cranking power, the AGM12-4 offers 3 Ah and 50 A against 4 Ah and 50 A. The Exide ETX4L-BS is 85 mm tall, with 3 Ah and 50 A. Before choosing between the EB4L-B and the AGM12-4, measure the free height of the battery compartment with the cover or bonnet closed.

### How much does the Exide EB4L-B weigh?

1.6 kg, with 4 Ah of capacity. For reference, the Exide AGM12-5 (4 Ah) weighs 1.8 kg.

### Which battery is equivalent to the Exide EB4L-B?

With the same dimensions, polarity and similar capacity you have the Varta YB4L-B and Fulbat FB4L-B. As the EB4L-B is a conventional battery, an EFB or AGM of the same size also works.

### Which side is the positive terminal on the Exide EB4L-B?

On the EB4L-B, 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.

### Does the Exide EB4L-B come charged and ready to fit?

Sealed AGM and gel batteries leave the factory charged and ready. Conventional ones with a separate acid pack are activated when filled and should be charged before fitting.

## Inside the EB4L-B: lead-acid technology

The EB4L-B is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.
