Where the Varta A13 fits
The Varta A13 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. If your car has no Start-Stop and had a 40 Ah battery, the A13 is a direct replacement.
At 40 Ah it is a small size: the usual choice for petrol superminis and city cars with little equipment. Varta lists the A13 in its Dynamic SLI line. More Varta batteries

Before ordering the A13, check this
- If your car has Start-Stop, the A13 is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 330 A or less, the A13 covers your engine.
- Your current battery should say about 40 Ah; a little more is also fine.
- Polarity of the A13: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Measure the space: the A13 takes up 187 × 140 × 227 mm.
