Format and fitting of the Varta YTX7A-4

The Varta YTX7A-4 is made in the 150 × 87 × 95 mm format. The positive terminal on the left determines which side the cables end up on: it is the detail behind most mistaken purchases, so it is worth checking before ordering. It uses a B00 hold-down, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal layout before buying avoids the most common mistake when replacing a battery.

The Varta YTX7A-4 and the Powersports AGM Active range

The Powersports AGM Active range consists of AGM motorcycle batteries activated and charged at the factory, ready to fit. They pair the toughness of AGM technology with the convenience of immediate installation.

They are aimed at general motorcycle and scooter use, with reliable starting and no maintenance from day one.

Unlike a car battery, what matters here is power density in a minimal size and resistance to vibration. It is the direct substitute for the original motorcycle battery, with the advantage of reliable starting even in the cold and after periods of inactivity. This battery used to belong to Varta's Powersports AGM High Performance range; following the brand's change of commercial naming (2025), it forms part of the new Powersports AGM Active series.

Why choose a Varta battery

When a workshop recommends Varta it is not down to marketing: it is one of the brands with the lowest return rates in the sector, with an application coverage spanning practically the whole European fleet, from the small hatchback to the commercial vehicle.

Varta batteries are made under the Clarios group with German technology and quality controls that make them one of the best-selling choices in Europe. As a lead battery, it is 100% recyclable through any collection point.

Varta's production combines automated lines with verification of more than 100 parameters per unit; that traceability is what underpins its reputation for reliable starting throughout the battery's life.

Manufacturer's warranty

The Varta YTX7A-4 battery comes with the official manufacturer warranty.

Care and maintenance

If the bike goes unused for long spells, a trickle charger greatly extends the battery's life and prevents sulphation. Storing it somewhere dry and checking the terminals at the start of each season helps it start first time. Motorcycle batteries suffer in the cold and when left idle: in winter, a maintenance charger stops the battery from discharging completely. With this care, it will typically deliver well over several years of service.
