## Description

## The Varta A7 at a glance

The Varta A7 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. In a Start-Stop car, the A7 keeps the radio, climate control and lights running with the engine off without losing capacity.
At 70 Ah it is the usual size for compact diesels and mid-size petrol saloons. Varta lists the A7 in its Dynamic AGM line. [The full range of Varta batteries](https://bateriasonline.es/en/varta-batteries)

## Varta A7 vs A8 and A6: which one to choose?

The real differences between the A7 and the closest Varta models:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta A7 (this one) | 70 Ah | 760 A | 278 × 175 × 190 | right | 20.3 kg |
| Varta A8 | 60 Ah | 680 A | 242 × 175 × 190 | right | 17.29 kg |
| Varta A6 | 80 Ah | 800 A | 315 × 175 × 190 | right | 22.56 kg |

- The Varta E39 is the previous name of this battery: Varta replaced it with the A7, keeping the same technology, capacity, cranking power and dimensions.
- Varta A8: 10 Ah less, 80 A less cranking power, a different case (242 × 175 × 190 mm).
- Varta A6: 10 Ah more, 40 A more cranking power, a different case (315 × 175 × 190 mm).

## What to look at before buying the A7

- Measure the space: the A7 takes up 278 × 175 × 190 mm (European case size L3).
- Polarity of the A7: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Capacity of the A7: 70 Ah; the same as your current battery or slightly more is fine.
- Check the EN amps on your battery: if it says 760 A or less, the A7 covers your engine.
- The A7 is AGM: it replaces an AGM or an EFB of the same size. You can swap an EFB for an AGM, but not an AGM for an EFB.

## AGM technology in the A7

The A7 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.

## Frequently asked questions about the Varta A7

### A7 or A8: which one suits me?

Compared with the A7, the Varta A8 has 10 Ah less and 80 A less cranking power. The A7 cranks harder; the A8 is only a good option if your original battery says 680 A or less. Mind the space: the A8 measures 242 × 175 × 190 mm.

### Does the Varta A7 replace the Varta E39?

Yes. The E39 is the previous name of this battery: Varta renamed it A7, with the same AGM technology, 70 Ah, 760 A cold cranking and a 278 × 175 × 190 mm case. If your car had an E39, the A7 is its direct replacement.

### What does the code 570 901 076 on the Varta A7 mean?

It is its ETN (European Type Number), also written 570901076. The first three digits (570) encode voltage and capacity: 12 V and 70 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (901) identifies the specific model within that capacity, and the last three digits (076) multiplied by 10 give the cold cranking current: 760 A.

### Can the Varta A7 be used in a car with Start-Stop?

Yes. As an AGM battery, the A7 handles automatic engine stop and brake energy recovery, and it can replace an EFB of the same size.

### How much does the Varta A7 weigh?

20.3 kg, with 70 Ah of capacity. For reference, the Varta A8 (60 Ah) weighs 17.29 kg.

### Which battery is equivalent to the Varta A7?

Only other AGM batteries with its dimensions and polarity: Fulmen FK700, Deta DK700 and Exide EK720. Neither an EFB nor a conventional battery replaces the A7. Its Bosch equivalent is the Bosch S5 A08 (same ETN code 570 901 076). Bosch is not part of our catalogue; we list it so you can compare.

### What case size is the Varta A7?

Case size L3: 278 × 175 × 190 mm (Varta lists it as H6/L3). The A7 fits any standard L3 battery tray such as the Fulmen FK700.
