Varta YB12A-B Powersports SLI Freshpack 12Ah 160A 12V Motorcycle Battery
The Varta YB12A-B motorcycle battery (reference 512015012) is the 12 V, 12 Ah model with 160 A of cold cranking power (EN) from Varta's Powersports SLI Freshpack range, designed for motorcycles, scooters, quads and personal watercraft. It replaces the original battery in motorcycles with the 136 × 82 × 162 mm format without any modifications: the same 12 Ah capacity and the same terminal layout (positive on the left).
- 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.
Applications of the Varta YB12A-B battery
With 12 Ah, the Varta YB12A-B is sized for motorcycles, scooters, quads and personal watercraft as a direct replacement for the original battery. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 4,46 kg and has a Y6 terminal.
Format and fitting of the Varta YB12A-B
Its external dimensions are 136 × 82 × 162 mm and it weighs 4,46 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 YB12A-B and the Powersports SLI Freshpack range
The Powersports SLI Freshpack is Varta's classic starter line for two-wheelers, with lead-acid technology and dry delivery with the acid packed separately to guarantee freshness until activation at the workshop.
It covers the bulk of motorbikes, scooters and quads fitted with a conventional battery: punchy starting, resistance to the vibrations of sporty riding and direct replacement of the original battery.
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
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.
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.
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 YB12A-B 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.

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?
Yes: it is a conventional lead-acid battery. Check the electrolyte level from time to time and, if it drops, top up with distilled water to the mark.
What is the service life of the YB12A-B model?
As a rough estimate, the Varta YB12A-B typically lasts 3 to 5 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 dimensions of the Varta YB12A-B battery?
Measure your motorcycle's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 136x82x162 mm. Height is measured to the top of the terminals.
Which side is the positive terminal on this battery?
Polarity of the Varta YB12A-B: positive on the left. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Seen from the front, terminals towards you, the positive (+) is the post with the red ring.
Does this battery fit my motorcycle?
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)). According to our data, 4 verified vehicle versions are compatible with the YB12A-B. If our table and the motorcycle handbook disagree, go with what the manufacturer says.
Which batteries are equivalent to the Varta YB12A-B?
A direct equivalent needs what this YB12A-B offers: 136×82×162 mm, positive on the left, the same Ah and CCA and conventional technology. The "Equivalents" section of this page gathers the recommended options with equivalent performance.
Varta YB12A-B or Varta YB12A-A: which one to choose?
Sister reference of the YB12A-B, practically identical on paper. Compared with the YB12A-B it has the same Ah and cranking power. It costs 24,90 € less. Choose by price and availability: in real use you will not notice a difference.
Varta YB12A-B or Motobatt MB12U: which one to choose?
Same case and same fitting as the YB12A-B, from Motobatt. Compared with the YB12A-B it has 3 Ah more. It costs 41,70 € more. If you want to save or the YB12A-B is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty.
