Varta YTX5L-4 Powersports AGM Active (formerly Powersports AGM High Performance) 4Ah 75A 12V Motorcycle Battery
The Varta YTX5L-4 motorcycle battery (reference 504909007) is the 12 V, 4 Ah model delivering 75 A of cold cranking power (EN), from Varta's Powersports AGM Active (formerly Powersports AGM High Performance) range, designed for motorcycles, scooters, quads and personal watercraft. Its 113 × 70 × 105 mm dimensions and positive terminal on the right make it the exact replacement for the 4 Ah battery fitted as standard in many motorcycles.
In short: the Varta YTX5L-4 (4 Ah, 75 A, 113 × 70 × 105 mm, positive terminal on the right). Verified equivalent alternatives: Exide AGM12-5 and Exide ETX5L-BS.
- Direct replacement for the original motorbike, scooter or quad battery.
- Construction built to withstand the vibration typical of two-wheelers.
- Performs well in the cold and after periods of inactivity.
- High cranking peak in a compact, lightweight format.

Format and fitting of the Varta YTX5L-4
The Varta YTX5L-4 is made in the 113 × 70 × 105 mm format. The positive terminal on the right determines which side the cables sit on: it is the detail that causes the most buying mistakes, so it is worth checking before you order. It uses a B00 hold-down, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal positions before buying avoids the most common mistake when replacing a battery.
The Varta YTX5L-4 and the Powersports AGM Active range
The Powersports AGM Active range consists of AGM motorcycle batteries activated and charged at the factory, ready to fit. They combine the toughness of AGM technology with the convenience of immediate installation.
They are aimed at general motorcycle and scooter use, with reliable starting and no maintenance from day one.
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. This battery used to belong to Varta's Powersports AGM High Performance range; following the brand's change of commercial naming (2025), it now forms part of the new Powersports AGM Active series.
Why choose a Varta battery
Varta is a byword for reliability: original equipment in 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 combines more than a century of experience with the industrial production of Clarios: it is the battery many manufacturers fit as standard and one of the most recommended by workshops. Like every lead-acid battery, it is 100% recyclable.
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 YTX5L-4 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 YTX5L-4 model AGM? What does this technology offer?
Yes. The YTX5L-4 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 is the Varta YTX5L-4 battery installed in the vehicle?
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 our blog. 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 — with positive on the right 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 YTX5L-4 battery last?
Expected lifespan of the Varta YTX5L-4 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 113×70×105 mm — also written as 113x70x105 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.
On which side is the positive of the YTX5L-4 model?
Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.
Does this 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 YTX5L-4 fits 109 verified vehicle versions in our database.
Which batteries are equivalent to the Varta YTX5L-4?
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.
