Where the Varta J1 fits
The Varta J1 turns heavy diesel engines and powers cabs with high consumption. The J1 is fitted alone or in pairs, in series, for the 24 V system of many trucks.
In the Varta catalogue, the J1 belongs to the Promotive SLI line. See all Varta batteries
What it means that the J1 is lead-acid
Inside, the J1 is classic lead-acid: liquid electrolyte and lead plates. If the J1 is left discharged for weeks it sulphates: a maintenance charger prevents this.
Varta J1 vs I18, J2 and I9: differences
The real differences between the J1 and the closest Varta models:
| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta J1 (this one) | 125 Ah | 720 A | 349 × 175 × 285 | right | 30.43 kg |
| Varta I18 | 110 Ah | 680 A | 349 × 175 × 236 | right | 28.71 kg |
| Varta J2 | 125 Ah | 720 A | 349 × 175 × 285 | left | 30.43 kg |
| Varta I9 | 120 Ah | 780 A | 349 × 175 × 236 | right | 29.01 kg |
| Varta G1 | 90 Ah | 540 A | 347 × 173 × 234 | right | 25.2 kg |
- Varta I18: 15 Ah less, 40 A less cranking power, a different case (349 × 175 × 236 mm).
- Varta J2: identical to the J1 except for the positive terminal, which is on the other side (positive terminal on the left).
- Varta I9: 5 Ah less, 60 A more cranking power, a different height (236 mm instead of 285 mm). It is the option if your battery tray cannot take the 285 mm height of the J1.

Check this before ordering the Varta J1
- Check the EN amps on your battery: if it says 720 A or less, the J1 covers your engine.
- Your current battery should say about 125 Ah; a little more is also fine.
- With the terminals facing you, the positive terminal of the J1 is on the right.
- The J1 needs 349 × 175 × 285 mm of space: measure it with the hold-down clamp in place.
Frequently asked questions about the Varta J1
Varta J1 or I18?
Compared with the J1, the Varta I18 has 15 Ah less and 40 A less cranking power. The J1 cranks harder; the I18 is only a good option if your original battery says 680 A or less. Mind the space: the I18 measures 349 × 175 × 236 mm.
What is the difference between the Varta J1 and the J2?
They are the same battery with the terminals swapped: positive terminal on the right on the J1, positive terminal on the left on the J2. Look at your current battery with the terminals facing you and pick the one that matches. That is why their ETNs only differ in the middle group: 625 012 072 for the J1 and 625 014 072 for the J2.
Varta J1 or I9: what changes?
Mainly the height: the J1 is 285 mm tall and the Varta I9 236 mm, with the same length and width. In capacity and cranking power, the I9 offers 120 Ah and 780 A against 125 Ah and 720 A. Before choosing between the J1 and the I9, measure the free height of the battery compartment with the cover or bonnet closed.
What does the code 625 012 072 on the Varta J1 mean?
It is its ETN (European Type Number), also written 625012072. 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 (012) 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 J2, is 625 014 072: only the middle group changes.
How much does the Varta J1 weigh?
The J1 weighs 30.43 kg. For reference, the Varta I18 (110 Ah) weighs 28.71 kg.
Which battery is equivalent to the Varta J1?
With the same dimensions, polarity and similar capacity you have the Exide EG1250, Tudor TG1250 and Fulmen FG1250. As the J1 is a conventional battery, an EFB or AGM of the same size also works.
Which charger does the Varta J1 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.
