## Lead-acid technology in the M7

Inside, the M7 is classic lead-acid: liquid electrolyte and lead plates. If the M7 is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Varta M7 vs M12 and M18: differences

Torn between the M7 and another similar Varta? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Weight |
|---|---|---|---|---|
| Varta M7 (this one) | 180 Ah | 1,100 A | 513 × 223 × 223 | 44.99 kg |
| Varta M12 | 180 Ah | 1,400 A | 513 × 223 × 223 | 46.42 kg |
| Varta M18 | 180 Ah | 1,000 A | 513 × 223 × 223 | 41.76 kg |

- Varta M12: the same capacity, 300 A more cranking power, the same dimensions.
- Varta M18: the same capacity, 100 A less cranking power, the same dimensions.

- Length, width and height of the M7: 513 × 223 × 223 mm.

## Frequently asked questions about the Varta M7

### M7 or M12: which one suits me?

Compared with the M7, the Varta M12 has 300 A more cranking power. If your current battery says 1,400 A or more, choose the M12; if it says 1,100 A or less, the M7 is enough. Both measure 513 × 223 × 223 mm, so they fit the same tray.

### What does the code 680 033 110 on the Varta M7 mean?

It is its ETN (European Type Number), also written 680033110. The first three digits (680) encode voltage and capacity: 12 V and 180 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (033) identifies the specific model within that capacity, and the last three digits (110) multiplied by 10 give the cold cranking current: 1,100 A.

### How much does the Varta M7 weigh?

44.99 kg, with 180 Ah of capacity. For reference, the Varta M12 (180 Ah) weighs 46.42 kg.

### Which battery is equivalent to the Varta M7?

With the same dimensions, polarity and similar capacity you have the Kronobat HD-180.4, Exide EG1803 and Kronobat SHD-180.3. As the M7 is a conventional battery, an EFB or AGM of the same size also works.

### Which charger does the Varta M7 need?

An automatic lead-acid charger with cut-off or maintenance mode, rated at 10 to 20% of its capacity in amps. If it is a vented type, check the electrolyte level and top up only with distilled water.
