## Description

## Who the Exide EA456 is for

The Exide EA456 is made for petrol and diesel cars without automatic engine stop. The EA456 covers the daily routine of a car without automatic engine stop: cold starts, short trips and loads with the ignition off.
At 45 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. The EA456 belongs to the Exide EXIDE Premium range. [The full range of Exide batteries](https://bateriasonline.es/en/exide-batteries)

## Equivalents and alternatives to the Exide EA456

Batteries that fit the EA456's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the EA456.

| Model | Technology | Capacity | Cold cranking (EN) | Dimensions (mm) |
|---|---|---|---|---|
| Tudor TA456 | Lead-acid | 45 Ah | 390 A | 237 × 127 × 227 |
| Fulmen FA456 | Lead-acid | 45 Ah | 390 A | 237 × 127 × 227 |

| Long 46B24L-MF | | 45 Ah | – | 236 × 127 × 225 |
| Long 46B24L(S) | | 45 Ah | – | 238 × 129 × 227 |
| Long 46B24L(S)-MF | | 45 Ah | – | 236 × 127 × 225 |

## Lead-acid technology in the EA456

Inside, the EA456 is classic lead-acid: liquid electrolyte and lead plates. If the EA456 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Check this before ordering the Exide EA456

- If your car has Start-Stop, the EA456 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 390 A or less, the EA456 covers your engine.
- Your current battery should say about 45 Ah; a little more is also fine.
- Polarity of the EA456: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- The EA456 needs 237 × 127 × 227 mm of space (European case size B24): measure it with the hold-down clamp in place.

## Frequently asked questions about the Exide EA456

### EA456 or EB454: which one suits me?

Compared with the EA456, the Exide EB454 has 60 A less cranking power. The EA456 cranks harder; the EB454 is only a good option if your original battery says 330 A or less. Both measure 237 × 127 × 227 mm, so they fit the same tray.

### Can the Exide EA456 be used in a car with Start-Stop?

No. The EA456 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Exide EA456 weigh?

11.8 kg, with 45 Ah of capacity. For reference, the Exide EB454 (45 Ah) weighs 11.4 kg.

### Which battery is equivalent to the Exide EA456?

With the same dimensions, polarity and similar capacity you have the Tudor TA456, Fulmen FA456 and Deta DA456. As the EA456 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Exide EA456?

Case size B24: 237 × 127 × 227 mm. The EA456 fits any standard B24 battery tray such as the Tudor TA456.

### Which side is the positive terminal on the Exide EA456?

On the EA456, 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 new battery need to be registered in the car?

In cars with energy management (common since 2010) it is worth registering the battery in the control unit so it adjusts charging. In older cars you just connect it.
