The Varta YT14B-BS motorcycle battery (reference 512903013) is the 12 V, 13 Ah model with 190 A of cold cranking power (EN) from Varta's Powersports AGM range, designed for motorcycles, scooters, quads and personal watercraft. With dimensions of 152 × 70 × 150 mm and the positive terminal on the left, it is the direct replacement for motorcycles fitted from the factory with a 13 Ah battery in this format.
- High cranking peak in a compact, lightweight format.
- Performs well in the cold and after periods of inactivity.
- Construction built to withstand the vibration typical of two-wheelers.
- Direct replacement for the original motorbike, scooter or quad battery.
Applications of the Varta YT14B-BS battery
The Varta YT14B-BS covers the needs of motorcycles, scooters, quads and personal watercraft with 13 Ah of capacity and a construction built for that use. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 4,7 kg and has a Y11 terminal.
Format and fitting of the Varta YT14B-BS
The Varta YT14B-BS is made in the 152 × 70 × 150 mm format and weighs 4,7 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 YT14B-BS and the Powersports AGM range
Varta's Powersports AGM series uses AGM technology (electrolyte absorbed in glass fibre): sealed, maintenance-free motorcycle batteries with very high vibration resistance that can be fitted in almost any position with no risk of spillage.
They are designed for today's motorcycles and scooters with plenty of electrical equipment, which demand reliable starting and zero maintenance throughout the battery's life.
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.
Why choose a Varta battery
Choosing Varta means sticking with the reference the vehicle manufacturer itself approved in the first place. Against own-brand batteries, the difference is not the purchase price but how many winters the battery lasts before leaving you stranded.
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 YT14B-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.

How to change the battery
Guide to replace your motorcycle battery in 10-15 minutes. Motorcycle batteries are light (2-5 kg) and usually need an 8 mm wrench.
Step 1. Prepare the vehicle
Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.
Step 2. Locate the battery compartment
On motorcycles it is usually under the seat, in the rear cowl or behind a side panel. Check the manual — access varies a lot between models.
Step 3. Disconnect the negative (−) terminal
Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery
Loosen the hold-down clamp or the straps that secure it. Lift the battery carefully — typical weight 2-5 kg. Check the terminals are not corroded before fitting the new one.
Step 6. Install the new battery
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
Step 7. Connect the cables
Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.
Step 8. Verify the engine starts
Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.
Frequently asked questions
Is the Varta YT14B-BS an AGM battery and what are the benefits of AGM?
Yes. The YT14B-BS from Varta uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for motorcycles with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
How do I change this battery step by step?
In most motorcycles it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On motorcycles with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the Varta YT14B-BS battery last?
Expected lifespan of the Varta YT14B-BS is 5 to 8 years in mild-climate motorcycle use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What size is this battery?
Dimensions (length × width × height) are 152×70×150 mm — also written as 152x70x150 mm — following the European DIN standard. Always measure the space in your motorcycle before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Will the Varta YT14B-BS battery fit my motorcycle?
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The YT14B-BS typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the YT14B-BS model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop motorcycles. See the "Equivalents" section to view recommended options at the same performance level.
