## Description

## The Varta B19 at a glance

The Varta B19 is made for petrol and diesel cars without automatic engine stop. If your car has no Start-Stop and had a 45 Ah battery, the B19 is a direct replacement.
At 45 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. In the Varta catalogue, the B19 belongs to the Dynamic SLI line. [See all Varta batteries](https://bateriasonline.es/en/varta-batteries)

## Varta B19 vs C22, B20 and B18

How the B19 compares with Varta batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta B19 (this one) | 45 Ah | 400 A | 207 × 175 × 190 | right | 11.46 kg |
| Varta C22 | 52 Ah | 470 A | 207 × 175 × 190 | right | 12.02 kg |
| Varta B20 | 45 Ah | 400 A | 207 × 175 × 190 | left | 11.46 kg |
| Varta B18 | 44 Ah | 440 A | 207 × 175 × 175 | right | 10.91 kg |
| Varta C30 | 54 Ah | 530 A | 207 × 175 × 190 | right | 12.59 kg |

- Varta C22: 7 Ah more, 70 A more cranking power, the same L1 case.
- If the positive terminal of your battery is on the other side, the one you need is the Varta B20 (positive terminal on the left).
- Varta B18: 1 Ah less, 40 A more cranking power, a different height (175 mm instead of 190 mm, LB1). It is the option if your battery tray cannot take the 190 mm height of the B19.
- Varta C30: 9 Ah more, 130 A more cranking power, the same L1 case.

## Equivalents and alternatives to the Varta B19

Same dimensions and polarity as the B19, with similar capacity and cranking power; as a conventional battery, the B19 can also be replaced by an EFB or AGM of the same size if you want more cycles.

|---|---|---|---|---|
| Kronobat SD-45.0 | Lead-acid | 45 Ah | 400 A | 207 × 175 × 190 |
| Exide EC440 | Lead-acid | 44 Ah | 360 A | 207 × 175 × 190 |

## Inside the B19: lead-acid technology

Inside, the B19 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 B19

- If your car has Start-Stop, the B19 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 400 A or less, the B19 covers your engine.
- With 45 Ah, the B19 replaces an original battery of that capacity or slightly less.
- Polarity of the B19: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Length, width and height of the B19: 207 × 175 × 190 mm (European case size L1).

## Frequently asked questions about the Varta B19

### Varta B19 or C22?

Compared with the B19, the Varta C22 has 7 Ah more and 70 A more cranking power. If your current battery says 470 A or more, choose the C22; if it says 400 A or less, the B19 is enough. Both measure 207 × 175 × 190 mm, so they fit the same tray.

### What is the difference between the Varta B19 and the B20?

They are the same battery with the terminals swapped: positive terminal on the right on the B19, positive terminal on the left on the B20. 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: 545 412 040 for the B19 and 545 413 040 for the B20.

### Varta B19 or B18: what changes?

Mainly the height: the B19 is 190 mm tall (L1) and the Varta B18 175 mm (LB1), with the same length and width. In capacity and cranking power, the B18 offers 44 Ah and 440 A against 45 Ah and 400 A. Before choosing between the B19 and the B18, measure the free height of the battery compartment with the cover or bonnet closed.

### What does the code 545 412 040 on the Varta B19 mean?

It is its ETN (European Type Number), also written 545412040. The first three digits (545) encode voltage and capacity: 12 V and 45 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (412) identifies the specific model within that capacity, and the last three digits (040) multiplied by 10 give the cold cranking current: 400 A. Its twin with the positive terminal on the other side, the Varta B20, is 545 413 040: only the middle group changes.

### Can the Varta B19 be used in a car with Start-Stop?

No. The B19 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Varta B19 weigh?

The B19 weighs 11.46 kg. For reference, the Varta C22 (52 Ah) weighs 12.02 kg.

### Which battery is equivalent to the Varta B19?

With the same dimensions, polarity and similar capacity you have the Kronobat SD-45.0, Exide EC440 and Tudor TC440. As the B19 is a conventional battery, an EFB or AGM of the same size also works.
