## Quick description

The Varta E46 (ETN 575 500 073, also written E 46 or 575500073) is a Start-Stop battery (EFB) with 12 V, 75 Ah and 730 A cold cranking current, case size LB4 (315 × 175 × 175 mm), with the positive terminal on the right.

## Description

## Where the Varta E46 fits

The Varta E46 is a battery for cars with Start-Stop: it withstands many more starting and partial-discharge cycles than a conventional battery and powers the electronics every time the engine stops at the lights. It takes repeated discharges without losing capacity the way a conventional battery would.
At 75 Ah it sits in the range of compact and mid-size diesels, SUVs and MPVs. Varta lists the E46 in its Dynamic EFB line. [The full range of Varta batteries](https://bateriasonline.es/en/varta-batteries)

## Varta E46 vs N80 and A6

Torn between the E46 and another similar Varta? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta E46 (this one) | 75 Ah | 730 A | 315 × 175 × 175 | right | 20.55 kg |
| Varta N80 | 80 Ah | 800 A | 315 × 175 × 190 | right | 21.13 kg |
| Varta A6 | 80 Ah | 800 A | 315 × 175 × 190 | right | 22.56 kg |

- Varta N80: 5 Ah more, 70 A more cranking power, a different case (315 × 175 × 190 mm).
- Varta A6: 5 Ah more, 70 A more cranking power, a different case (315 × 175 × 190 mm), AGM technology.

## Part numbers and codes for the Varta E46

The E46 is listed under these codes on labels, in garages and in catalogues:

## Equivalents and alternatives to the Varta E46

As the E46 is an EFB, only EFB or AGM batteries of the same size and polarity are listed: you can step up to AGM, but not down to a conventional battery.

| Model | Technology | Capacity | Cold cranking (EN) | Dimensions (mm) |
|---|---|---|---|---|
| Exide EL752 | EFB | 75 Ah | 730 A | 315 × 175 × 175 |
| Kronobat PE-75-EFB | EFB | 75 Ah | 730 A | 315 × 175 × 175 |
| Tudor TL752 | EFB | 75 Ah | 730 A | 315 × 175 × 175 |
| Fulmen FL752 | EFB | 75 Ah | 730 A | 315 × 175 × 175 |
| Deta DL752 | EFB | 75 Ah | 730 A | 315 × 175 × 175 |

## Before ordering the E46, check this

- Length, width and height of the E46: 315 × 175 × 175 mm (European case size LB4).
- Polarity of the E46: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Capacity of the E46: 75 Ah; the same as your current battery or slightly more is fine.
- The E46 delivers 730 A cold cranking (EN standard); do not go below what your original battery states.
- The E46 is an EFB: it suits cars that had an EFB or a conventional battery. If yours had an AGM, fit another AGM.

## EFB technology in the E46

The E46 is an EFB: flooded lead-acid with reinforced plates and separators for Start-Stop. It can be replaced by an AGM, but an AGM must never be replaced by an EFB.

## Frequently asked questions about the Varta E46

### E46 or N80: which one suits me?

Compared with the E46, the Varta N80 has 5 Ah more and 70 A more cranking power. If your current battery says 800 A or more, choose the N80; if it says 730 A or less, the E46 is enough. Mind the space: the N80 measures 315 × 175 × 190 mm.

### What does the code 575 500 073 on the Varta E46 mean?

It is its ETN (European Type Number), also written 575500073. The first three digits (575) encode voltage and capacity: 12 V and 75 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (500) identifies the specific model within that capacity, and the last three digits (073) multiplied by 10 give the cold cranking current: 730 A.

### Can the Varta E46 be used in a car with Start-Stop?

Yes, the E46 is an EFB: it suits Start-Stop without brake energy recovery, or cars that already had an EFB. If your car left the factory with an AGM, fit another AGM.

### How much does the Varta E46 weigh?

20.55 kg, with 75 Ah of capacity. For reference, the Varta N80 (80 Ah) weighs 21.13 kg.

### Which battery is equivalent to the Varta E46?

In EFB or AGM, with its dimensions and polarity: Exide EL752, Kronobat PE-75-EFB and Tudor TL752. A conventional battery does not replace the E46.

### What case size is the Varta E46?

Case size LB4: 315 × 175 × 175 mm (Varta lists it as T7/LB4). The E46 fits any standard LB4 battery tray such as the Exide EL752.

### Which side is the positive terminal on the Varta E46?

On the E46, 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.
