One battery is equivalent to another when it has the same voltage and polarity, the same dimensions (within 4 mm), a similar capacity (within 6 %) and the same or a better technology. The table gives you the Exide, Tudor, Fulmen and Deta equivalent for the 17 most searched-for Varta car batteries, plus the Bosch with the same ETN code for reference.

bateriasonline.es does not sell Bosch: that column is for reference only, based on matching ETN codes published in distributors' catalogues. If a match has not been verified, the cell is left empty. In brackets, the technology of the equivalent where it is better than the Varta's.

## How we pick each equivalent

We apply the same rules as on all our product pages ([explained here](https://bateriasonline.es/en/how-we-write-our-battery-datasheets)):
- **Same voltage** (12 V) and **same polarity**: the positive terminal on the same side.
- **Capacity** within 6 %: a 74 Ah E11 accepts equivalents from 70 to 78 Ah.
- **Cold cranking** between 90 % and 120 % of the original.
- **Length, width and height** within 4 mm, so it fits the tray and the hold-down.
- **Same or better technology:** a conventional battery can be replaced by an EFB or AGM; an EFB by an EFB or AGM; an AGM only by an AGM. For Start-Stop cars we only suggest Start-Stop batteries.

Where a brand offers several options, we show the one with the same technology and the closest capacity.

## How to read Exide, Tudor, Fulmen and Deta codes

Exide, Tudor, Fulmen and Deta share the same reference system. The first letter gives the brand and the second the technology:
- **E** = Exide, **T** = Tudor, **F** = Fulmen, **D** = Deta.
- **K** = AGM (for example EK720 or TK720) and **L** = EFB (EL700, TL700): these are the Start-Stop batteries.
- **A, B and C** = conventional lead-acid batteries (EA770, EB740, EC700).
- The digits give the approximate capacity (EB740 = 74 Ah); the last one marks variants such as polarity (the EB741 has the positive on the left). Always check the datasheet.

## And what do the Varta letters mean?

With Varta, the first letter does not indicate the technology: the E11, D24 and B18 are conventional batteries from the Dynamic SLI range; those starting with A (A6, A7, A8) are AGM, and those starting with N (N70, N80) are EFB. The safe way to compare is the 9-digit ETN code printed on the label.

## Frequently asked questions

### What is the ETN code and why is it useful for comparing brands?

The ETN (European Type Number) is a 9-digit code that sums up the battery's capacity, characteristics and format. Varta, Bosch and other manufacturers show it on their batteries and datasheets, so the same ETN means the same specification even if the brand changes.

### Can I fit a battery with more cold cranking amps?

Yes, as long as the dimensions and polarity are the same. The car only draws the current it needs, and slightly higher cold cranking gives you more margin in winter.

### Can I swap a conventional battery for an AGM or EFB?

Yes, it is an upgrade. What you should not do is the opposite on a Start-Stop car: if it has an AGM, the replacement must be AGM.

### Are Exide, Tudor, Fulmen and Deta the same battery?

They share a reference system and, on our datasheets, the same technical specs for each equivalent reference (for example EB740, TB740, FB740 and DB740). Each brand has its own range and warranty.

### Why don't you sell Bosch?

It is not part of our range. We include it only so you can find the equivalent if your current battery is a Bosch: look up its ETN and choose the Varta, Exide or Tudor in the same row.
