## Description

## Where the Exide EN900 fits

The Exide EN900 is a battery for boats: engine starting or on-board service, depending on its design, with resistance to damp and hull vibration. With 140 Ah, the EN900 suits boats that had a battery of that capacity.
The EN900 belongs to the Exide EXIDE MARINA START range. [See all Exide batteries](https://bateriasonline.es/en/exide-batteries)

## Inside the EN900: lead-acid technology

The EN900 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the EN900 needs no special registration: just connect it.

## Exide EN900 vs ER660 and ET950: differences

What sets the EN900 apart from its neighbours in the Exide range:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Weight |
|---|---|---|---|---|
| Exide EN900 (this one) | 140 Ah | 800 A | 513 × 189 × 223 | 34.1 kg |
| Exide ER660 | 140 Ah | 750 A | 513 × 189 × 223 | 37.3 kg |
| Exide ET950 | 135 Ah | 700 A | 513 × 189 × 223 | 39.5 kg |

- Exide ER660: the same capacity, 50 A less cranking power, the same dimensions.
- Exide ET950: 5 Ah less, 100 A less cranking power, the same dimensions.

## Equivalents and alternatives to the Exide EN900

Batteries that fit the EN900's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the EN900.

| Model | Technology | Capacity | Cold cranking (EN) | Dimensions (mm) |
|---|---|---|---|---|
| Varta LFD140 | Lead-acid | 140 Ah | 800 A | 513 × 189 × 223 |
| Varta LED140 | EFB | 140 Ah | 800 A | 513 × 189 × 223 |

## Check this before ordering the Exide EN900

- Check the EN amps on your battery: if it says 800 A or less, the EN900 covers your engine.
- Capacity of the EN900: 140 Ah; the same as your current battery or slightly more is fine.
- Length, width and height of the EN900: 513 × 189 × 223 mm.

## Frequently asked questions about the Exide EN900

### EN900 or ER660: which one suits me?

Compared with the EN900, the Exide ER660 has 50 A less cranking power. The EN900 cranks harder; the ER660 is only a good option if your original battery says 750 A or less. Both measure 513 × 189 × 223 mm, so they fit the same tray.

### How much does the Exide EN900 weigh?

34.1 kg, with 140 Ah of capacity. For reference, the Exide ER660 (140 Ah) weighs 37.3 kg.

### Which battery is equivalent to the Exide EN900?

With the same dimensions, polarity and similar capacity you have the Varta LFD140, Varta LED140 and Exide ER660. As the EN900 is a conventional battery, an EFB or AGM of the same size also works.

### How do I look after the boat battery in winter?

Leave it 100% charged, disconnected or on a marine maintenance charger. A battery that spends the winter half-discharged loses capacity permanently.
