## Varta K11 vs J10 and I2: which one to choose?

Torn between the K11 and another similar Varta? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta K11 (this one) | 143 Ah | 900 A | 508 × 174 × 205 | right | 36.5 kg |
| Varta J10 | 130 Ah | 1,000 A | 514 × 175 × 210 | – | 35.46 kg |
| Varta I2 | 110 Ah | 760 A | 514 × 175 × 210 | – | 30.9 kg |

- Varta J10: 13 Ah less, 100 A more cranking power, a different case (514 × 175 × 210 mm).
- Varta I2: 33 Ah less, 140 A less cranking power, a different case (514 × 175 × 210 mm).

## Lead-acid technology in the K11

Inside, the K11 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.

## Check this before ordering the Varta K11

- The K11 needs 508 × 174 × 205 mm of space: measure it with the hold-down clamp in place.
- The K11 has the positive terminal on the right: compare it with your current battery.
- Your current battery should say about 143 Ah; a little more is also fine.
- Cold cranking: 900 A (EN), equal to or higher than the original.

## Frequently asked questions about the Varta K11

### K11 or J10: which one suits me?

Compared with the K11, the Varta J10 has 13 Ah less and 100 A more cranking power. If your current battery says 1,000 A or more, choose the J10; if it says 900 A or less, the K11 is enough. Mind the space: the J10 measures 514 × 175 × 210 mm.

### What does the code 643 107 090 on the Varta K11 mean?

It is its ETN (European Type Number), also written 643107090. The first three digits (643) encode voltage and capacity: 12 V and 143 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (107) identifies the specific model within that capacity, and the last three digits (090) multiplied by 10 give the cold cranking current: 900 A.

### How much does the Varta K11 weigh?

36.5 kg, with 143 Ah of capacity. For reference, the Varta J10 (130 Ah) weighs 35.46 kg.

### Which battery is equivalent to the Varta K11?

With the same dimensions, polarity and similar capacity you have the Exide EG1402, Tudor TG1402 and Fulmen FG1402. As the K11 is a conventional battery, an EFB or AGM of the same size also works.

### Which side is the positive terminal on the Varta K11?

On the K11, 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.

### Are truck batteries fitted in pairs?

Almost always, in series for 24 V. Replace them in matched pairs: mixing a new one with an old one unbalances charging and shortens the new one's life.
