The Varta A14 at a glance
The Varta A14 is a starter battery for cars without Start-Stop: it delivers the current the starter motor needs and then powers lights, control units and audio with the engine off. Its job is to start the engine in the cold with margin to spare and keep the car's electronics powered.
At 40 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. Varta lists the A14 in its Dynamic SLI line. More Varta batteries

Equivalents and alternatives to the Varta A14
Same dimensions and polarity as the A14, with similar capacity and cranking power; as a conventional battery, the A14 can also be replaced by an EFB or AGM of the same size if you want more cycles.
| Model | Technology | Capacity | Cold cranking (EN) | Dimensions (mm) |
|---|---|---|---|---|
| Kronobat PB-40.0T | Lead-acid | 40 Ah | 330 A | 187 × 127 × 227 |
| Kronobat PB-40.0F | Lead-acid | 40 Ah | 330 A | 187 × 127 × 227 |
What it means that the A14 is lead-acid
The A14 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the A14 needs no special registration: just connect it.
What to look at before buying the A14
- If your car has Start-Stop, the A14 is not the right one: it needs an EFB or an AGM.
- Cold cranking: 330 A (EN), equal to or higher than the original.
- Capacity of the A14: 40 Ah; the same as your current battery or slightly more is fine.
- Polarity of the A14: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- The A14 needs 187 × 127 × 227 mm of space (European case size B19): measure it with the hold-down clamp in place.
Frequently asked questions about the Varta A14
Varta A14 or B23?
Compared with the A14, the Varta B23 has 5 Ah more and 30 A less cranking power. The A14 cranks harder; the B23 is only a good option if your original battery says 300 A or less. Mind the space: the B23 measures 220 × 135 × 225 mm.
What is the difference between the Varta A14 and the A15?
They are the same battery with the terminals swapped: positive terminal on the right on the A14, positive terminal on the left on the A15. 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: 540 126 033 for the A14 and 540 127 033 for the A15.
What does the code 540 126 033 on the Varta A14 mean?
It is its ETN (European Type Number), also written 540126033. The first three digits (540) encode voltage and capacity: 12 V and 40 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (126) identifies the specific model within that capacity, and the last three digits (033) multiplied by 10 give the cold cranking current: 330 A. Its twin with the positive terminal on the other side, the Varta A15, is 540 127 033: only the middle group changes.
Can the Varta A14 be used in a car with Start-Stop?
No. The A14 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM.
How much does the Varta A14 weigh?
The A14 weighs 9.49 kg. For reference, the Varta B23 (45 Ah) weighs 10.7 kg.
Which battery is equivalent to the Varta A14?
With the same dimensions, polarity and similar capacity you have the Kronobat PB-40.0T and Kronobat PB-40.0F. As the A14 is a conventional battery, an EFB or AGM of the same size also works.
What case size is the Varta A14?
Case size B19: 187 × 127 × 227 mm. The A14 fits any standard B19 battery tray such as the Kronobat PB-40.0T.
