FAQs about the Yuasa YBX3077

What should I pay attention to regarding terminal arrangement?

The YBX3077 has circuit 1, which means the positive terminal is left (when the terminals are facing the viewer). Many standard batteries have the positive terminal on the right (circuit 0). Please always compare this with your old battery, as the cables in the car are often not long enough to change sides.

Does the battery fit my Fiat or Alfa?

Very often, yes. The dimensions (207 x 175 x 190 mm) and performance often match exactly the requirements for petrol small cars of these brands. What is always decisive, however, are the exact dimensions of the battery box and the terminal arrangement.

Is the battery suitable for start-stop?

No. The YBX3077 is a conventional wet battery. It must not be used in vehicles with start-stop automation, as it cannot withstand the high cycle demands. For that you need an EFB or AGM battery.

What does base strip B3 mean?

B3 means that the battery has a fastening strip with a height of 10.5 mm on its long sides (front and back). This is important if your battery is secured to the floor of the vehicle with clamps.
