## Before ordering the A4, check this

- Length, width and height of the A4: 394 × 175 × 190 mm (European case size L6).
- With the terminals facing you, the positive terminal of the A4 is on the right.
- With 105 Ah, the A4 replaces an original battery of that capacity or slightly less.
- Check the EN amps on your battery: if it says 950 A or less, the A4 covers your engine.
- The A4 is AGM: it replaces an AGM or an EFB of the same size. You can swap an EFB for an AGM, but not an AGM for an EFB.

## What it means that the A4 is AGM

Inside, the A4 has glass fibre separators (AGM) that hold the electrolyte. The A4 needs a charger with an AGM mode that does not exceed 14.7 V.

## Frequently asked questions about the Varta A4

### A4 or A5: which one suits me?

Compared with the A4, the Varta A5 has 10 Ah less and 100 A less cranking power. The A4 cranks harder; the A5 is only a good option if your original battery says 850 A or less. Mind the space: the A5 measures 353 × 175 × 190 mm.

### Does the Varta A4 replace the Varta H15?

Yes, the A4 is the reference Varta offers instead of the H15.

### What does the code 605 901 095 on the Varta A4 mean?

It is its ETN (European Type Number), also written 605901095. The first three digits (605) encode voltage and capacity: 12 V and 105 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (901) identifies the specific model within that capacity, and the last three digits (095) multiplied by 10 give the cold cranking current: 950 A.

### Can the Varta A4 be used in a car with Start-Stop?

Yes. As an AGM battery, the A4 handles automatic engine stop and brake energy recovery, and it can replace an EFB of the same size.
