Format and fitting of the Varta YTX14L-BS
Its external dimensions are 150 × 87 × 146 mm. The positive terminal on the right 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 YTX14L-BS and the Powersports AGM Active range
The Powersports AGM Active series is Varta's AGM line for motorcycles that arrives activated and charged from the outset: it fits straight on, with no acid to add and no charging before use. It combines the robustness of AGM (resistance to vibration and to deep discharge) with maximum 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 starting 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 forms part of the new Powersports AGM Active series.
Why choose a Varta battery
A good share of the vehicles on Europe's roads left the factory with a Varta fitted: the brand has been supplying the assembly lines of the leading car groups for decades. Replacing with a Varta is, in practice, giving the vehicle back the battery its manufacturer intended.
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 YTX14L-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.
