Format and fitting of the Varta YT12B-BS
The Varta YT12B-BS is made in the 151 × 70 × 131 mm format and weighs 4,3 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. Checking the three dimensions and the terminal layout before buying avoids the most common mistake when replacing a battery.
The Varta YT12B-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.
Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year.
More than 100 manufacturing parameters are checked on every Varta battery before it leaves the plant, a level of rigour that explains why so many workshops and manufacturers trust the brand as their first-choice replacement.
Manufacturer's warranty
The Varta YT12B-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.

Frequently asked questions
Is the Varta YT12B-BS an AGM battery and what are the benefits of AGM?
Yes. AGM (Absorbent Glass Mat) technology, 12 Ah and 12 V: sealed lead-acid, with the electrolyte held in glass fibre. It tolerates heat better and handles more cycles than a conventional battery.
How should this motorcycle battery be charged?
With a 12 V motorcycle charger delivering at most 10 % of its capacity: 1.2 A for its 12 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.
Does it need maintenance?
No: being AGM, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time.
How long does the Varta YT12B-BS battery last?
As a rough estimate, the Varta YT12B-BS typically lasts 4 to 6 years, keeping it charged when the bike is not in use; it is a guide figure, not a guaranteed period. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance.
What are the measurements of the YT12B-BS model?
Its dimensions are 151×70×131 mm, also written 151x70x131 mm; the height already includes the terminals. Check the room available in your motorcycle, because a single millimetre too much can stop the clamp from closing.
What polarity does the Varta YT12B-BS battery have?
Polarity of the Varta YT12B-BS: positive on the left. Seen from the front, terminals towards you, the positive (+) is the post with the red ring. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering.
Is the YT12B-BS valid for my vehicle?
According to our data, 47 verified vehicle versions are compatible with the YT12B-BS. For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)).

Which batteries are equivalent to the Varta YT12B-BS?
A direct equivalent needs what this YT12B-BS offers: 151×70×131 mm, positive on the left, the same Ah and CCA and AGM technology. See the "Equivalents" section of this page for the recommended options at the same performance level.
Varta YT12B-BS or Exide ET12B-BS: which one to choose?
It has the same dimensions, voltage and technology as the YT12B-BS, although it is not a manufacturer-approved equivalent. Compared with the YT12B-BS it has 2 Ah less and 55 A of cold cranking less. It costs 31,20 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.
