## Check this before ordering the Varta A17

- Length, width and height of the A17: 207 × 175 × 175 mm (European case size LB1).
- Polarity of the A17: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- With 41 Ah, the A17 replaces an original battery of that capacity or slightly less.
- The A17 delivers 360 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the A17 is not the right one: it needs an EFB or an AGM.

## Inside the A17: lead-acid technology

Inside, the A17 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.

## Frequently asked questions about the Varta A17

### Varta A17 or B18?

Compared with the A17, the Varta B18 has 3 Ah more and 80 A more cranking power. If your current battery says 440 A or more, choose the B18; if it says 360 A or less, the A17 is enough. Both measure 207 × 175 × 175 mm, so they fit the same tray.

### What does the code 541 400 036 on the Varta A17 mean?

It is its ETN (European Type Number), also written 541400036. The first three digits (541) encode voltage and capacity: 12 V and 41 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (400) identifies the specific model within that capacity, and the last three digits (036) multiplied by 10 give the cold cranking current: 360 A.

### Can the Varta A17 be used in a car with Start-Stop?

No. The A17 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.

### How much does the Varta A17 weigh?

The A17 weighs 10.68 kg. For reference, the Varta B18 (44 Ah) weighs 10.91 kg.

### Which battery is equivalent to the Varta A17?

With the same dimensions, polarity and similar capacity you have the Kronobat SD-41.0B, Exide EC412 and Tudor TC412. As the A17 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Varta A17?

Case size LB1: 207 × 175 × 175 mm (Varta lists it as T4/LBN1). The A17 fits any standard LB1 battery tray such as the Kronobat SD-41.0B.
