## Lead-acid technology in the I9

Inside, the I9 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.

## Varta I9 vs I18, J1 and G1

How the I9 compares with Varta batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta I9 (this one) | 120 Ah | 780 A | 349 × 175 × 236 | right | 29.01 kg |
| Varta I18 | 110 Ah | 680 A | 349 × 175 × 236 | right | 28.71 kg |
| Varta J1 | 125 Ah | 720 A | 349 × 175 × 285 | right | 30.43 kg |
| Varta G1 | 90 Ah | 540 A | 347 × 173 × 234 | right | 25.2 kg |

- Varta I18: 10 Ah less, 100 A less cranking power, the same dimensions.
- Varta J1: 5 Ah more, 60 A less cranking power, a different height (285 mm instead of 236 mm). It only fits if there is room for 285 mm of height.
- Varta G1: 30 Ah less, 240 A less cranking power, the same dimensions.

## Equivalents and alternatives to the Varta I9

Batteries that fit the I9's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the I9.

## Check this before ordering the Varta I9

- Cold cranking: 780 A (EN), equal to or higher than the original.
- Your current battery should say about 120 Ah; a little more is also fine.
- With the terminals facing you, the positive terminal of the I9 is on the right.
- Measure the space: the I9 takes up 349 × 175 × 236 mm.

## Frequently asked questions about the Varta I9

### I9 or I18: which one suits me?

Compared with the I9, the Varta I18 has 10 Ah less and 100 A less cranking power. The I9 cranks harder; the I18 is only a good option if your original battery says 680 A or less. Both measure 349 × 175 × 236 mm, so they fit the same tray.

### Varta I9 or J1: what changes?

Mainly the height: the I9 is 236 mm tall and the Varta J1 285 mm, with the same length and width. In capacity and cranking power, the J1 offers 125 Ah and 720 A against 120 Ah and 780 A. Before choosing between the I9 and the J1, measure the free height of the battery compartment with the cover or bonnet closed.

### What does the code 620 047 078 on the Varta I9 mean?

It is its ETN (European Type Number), also written 620047078. The first three digits (620) encode voltage and capacity: 12 V and 120 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (047) identifies the specific model within that capacity, and the last three digits (078) multiplied by 10 give the cold cranking current: 780 A.

### How much does the Varta I9 weigh?

29.01 kg, with 120 Ah of capacity. For reference, the Varta I18 (110 Ah) weighs 28.71 kg.

### Which battery is equivalent to the Varta I9?

With the same dimensions, polarity and similar capacity you have the Exide EF1202, Tudor TF1202 and Fulmen FF1202. As the I9 is a conventional battery, an EFB or AGM of the same size also works.

### Which side is the positive terminal on the Varta I9?

On the I9, 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.

### Which charger does the Varta I9 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.
