• Direct replacement for the original motorbike, scooter or quad battery.
• Construction built to withstand the vibration typical of two-wheelers.

Applications of the Varta YT7B battery

Designed for motorcycles, scooters, quads and personal watercraft, the Varta YT7B is a direct replacement when you need its same 6 Ah capacity and format. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a B00 hold-down.

Format and fitting of the Varta YT7B

Its external dimensions are 150 × 66 × 93 mm. The positive terminal on the left determines which side the cables end up on: it is the detail that causes the most purchasing mistakes, so it is worth checking before ordering. It uses a B00 hold-down, the system that secures it to the vehicle's battery tray. For the replacement to be a direct fit, the space taken by your current battery must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

The Varta YT7B and the Powersports AGM Active range

The Powersports AGM Active series is Varta's AGM motorcycle line that arrives activated and charged from the factory: it fits straight on, with no acid to add and no charging before use. It combines the ruggedness of AGM (resistance to vibration and to deep discharge) with the greatest possible ease of installation.

In the new portfolio it also absorbs the former high-performance versions (AGM High Performance), so it covers everything from general use to large-capacity, custom and trail bikes with heavy cranking demands.

On two wheels, vibration and extreme temperatures take a heavy toll on the battery. This range reinforces the internal plate mounting and seals the unit to withstand that use, delivering the instant burst of cranking power a motorbike or quad engine needs after weeks standing idle. This battery used to belong to Varta's Powersports AGM High Performance range; following the brand's change of commercial naming (2025), it now forms part of the new Powersports AGM Active series.

Varta combines more than a century of experience with the industrial production of Clarios: it is the battery many manufacturers fit as standard and one of the most recommended by workshops. Like every lead-acid battery, it is 100% recyclable.

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 YT7B 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.
