## Quick description

Varta J2 (ETN 625 014 072, also written J 2 or 625014072): truck battery with 12 V, 125 Ah and 720 A cold cranking current, measuring 349 × 175 × 285 mm, with the positive terminal on the left. If yours has the positive terminal on the right, you need the Varta J1.

## Description

## Where the Varta J2 fits

The Varta J2 is a starter battery for trucks, tractors and machinery: high capacity, robust terminals and a build that withstands vibration and the starts of large engines. It is built to resist constant vibration and long shifts.
Varta lists the J2 in its Promotive SLI line. [The full range of Varta batteries](https://bateriasonline.es/en/varta-batteries)

## Inside the J2: lead-acid technology

The J2 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.

## Varta J2 vs I5, J1 and G2: which one to choose?

What sets the J2 apart from its neighbours in the Varta range:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta J2 (this one) | 125 Ah | 720 A | 349 × 175 × 285 | left | 30.43 kg |
| Varta I5 | 110 Ah | 680 A | 347 × 173 × 234 | left | 26.8 kg |
| Varta J1 | 125 Ah | 720 A | 349 × 175 × 285 | right | 30.43 kg |
| Varta G2 | 90 Ah | 540 A | 347 × 173 × 234 | left | 25.2 kg |

- Varta I5: 15 Ah less, 40 A less cranking power, a different case (347 × 173 × 234 mm).
- If the positive terminal of your battery is on the other side, the one you need is the Varta J1 (positive terminal on the right).
- Varta G2: 35 Ah less, 180 A less cranking power, a different case (347 × 173 × 234 mm).

## Equivalents and alternatives to the Varta J2

Batteries that fit the J2's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the J2.

## Before ordering the J2, check this

- Cold cranking: 720 A (EN), equal to or higher than the original.
- Your current battery should say about 125 Ah; a little more is also fine.
- The J2 has the positive terminal on the left: compare it with your current battery.
- The J2 needs 349 × 175 × 285 mm of space: measure it with the hold-down clamp in place.

## Frequently asked questions about the Varta J2

### J2 or I5: which one suits me?

Compared with the J2, the Varta I5 has 15 Ah less and 40 A less cranking power. The J2 cranks harder; the I5 is only a good option if your original battery says 680 A or less. Mind the space: the I5 measures 347 × 173 × 234 mm.

### Varta J2 or J1: what is the difference?

Only the polarity: the J2 has the positive terminal on the left and the J1 the positive terminal on the right. Capacity (125 Ah), cranking power and dimensions are identical. That is why their ETNs only differ in the middle group: 625 014 072 for the J2 and 625 012 072 for the J1.

### What does the code 625 014 072 on the Varta J2 mean?

It is its ETN (European Type Number), also written 625014072. The first three digits (625) encode voltage and capacity: 12 V and 125 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (014) identifies the specific model within that capacity, and the last three digits (072) multiplied by 10 give the cold cranking current: 720 A. Its twin with the positive terminal on the other side, the Varta J1, is 625 012 072: only the middle group changes.

### How much does the Varta J2 weigh?

30.43 kg, with 125 Ah of capacity. For reference, the Varta I5 (110 Ah) weighs 26.8 kg.

### Which battery is equivalent to the Varta J2?

With the same dimensions, polarity and similar capacity you have the Exide EG1251, Tudor TG1251 and Fulmen FG1251. As the J2 is a conventional battery, an EFB or AGM of the same size also works.

### What does HD or vibration resistance mean on a truck battery?

That the plates are fixed to withstand intense vibration (EN 50342 V3/V4). It is essential in construction, agriculture and long-haul transport.
