Who the Varta A15 is for
The Varta A15 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 A15 in its Dynamic SLI line. More Varta batteries

Before ordering the A15, check this
- Measure the space: the A15 takes up 187 × 127 × 227 mm (European case size B19).
- With the terminals facing you, the positive terminal of the A15 is on the left.
- Your current battery should say about 40 Ah; a little more is also fine.
- The A15 delivers 330 A cold cranking (EN standard); do not go below what your original battery states.
- If your car has Start-Stop, the A15 is not the right one: it needs an EFB or an AGM.
Inside the A15: lead-acid technology
The A15 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.
Frequently asked questions about the Varta A15
Varta A15 or A12?
Compared with the A15, the Varta A12 has 5 Ah less, 10 A more cranking power and AGM technology. If your current battery says 340 A or more, choose the A12; if it says 330 A or less, the A15 is enough. Mind the space: the A12 measures 196 × 126 × 223 mm.
What is the difference between the Varta A15 and the A14?
They are the same battery with the terminals swapped: positive terminal on the left on the A15, positive terminal on the right on the A14. 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: 540 127 033 for the A15 and 540 126 033 for the A14.
What does the code 540 127 033 on the Varta A15 mean?
It is its ETN (European Type Number), also written 540127033. 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 (127) 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 A14, is 540 126 033: only the middle group changes.
Can the Varta A15 be used in a car with Start-Stop?
No. The A15 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM; in this same size there is the Varta A12.
How much does the Varta A15 weigh?
The A15 weighs 9.49 kg. For reference, the Varta A12 (35 Ah) weighs 11 kg.
Which battery is equivalent to the Varta A15?
With the same dimensions, polarity and similar capacity you have the Kronobat PB-40.1F. As the A15 is a conventional battery, an EFB or AGM of the same size also works.
What case size is the Varta A15?
Case size B19: 187 × 127 × 227 mm (Varta lists it as B19R). The A15 fits any standard B19 battery tray such as the Kronobat PB-40.1F.
