The Varta YT7B-BS motorcycle battery (reference 507901012) is the 12 V, 7 Ah model with 120 A of cold cranking power (EN) from Varta's Powersports AGM range, designed for motorcycles, scooters, quads and personal watercraft.

- Construction built to withstand the vibration typical of two-wheelers.
- Direct replacement for the original motorbike, scooter or quad battery.
- High cranking peak in a compact, lightweight format.
- Performs well in the cold and after periods of inactivity.

Format and fitting of the Varta YT7B-BS
Its external dimensions are 150 × 66 × 94 mm and it weighs 2,8 kg. 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. Before replacing it, measure the space your current battery sits in: if it matches on all three dimensions and on the terminal layout, the swap is direct and needs no adapters.
The Varta YT7B-BS and the Powersports AGM range
The Powersports AGM range consists of sealed AGM motorcycle batteries, maintenance-free and ready to use, with immobilised electrolyte that makes them resistant to vibration and suitable for any mounting position.
They are the choice for modern motorcycles and scooters with on-board electronics, where the aim is zero maintenance and reliable starting with no leaks and no topping up with acid.
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.
Why choose a Varta battery
Varta is a byword for reliability: original equipment on numerous European vehicles and one of the most proven brands on the market. Replacing your battery with a Varta restores OEM quality — the same performance as the factory-fitted unit — with the manufacturer's backing.
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 is Europe's leading manufacturer of starter batteries: its production volume and its quality controls guarantee consistent reliability batch after batch, something own-brand makes cannot always promise.
Manufacturer's warranty
The Varta YT7B-BS 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.
