## Description

## Varta YTX7A-4 Powersports AGM Active (formerly Powersports AGM High Performance) 6Ah 90A 12V Motorcycle Battery

JIS code YTX7A-4
12*V* Voltage
6*Ah* Capacity
90*A* Cold cranking

The **Varta YTX7A-4 motorcycle battery** (reference 506909009) is the **12 V**, **6 Ah** model with **90 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. It replaces the original battery in motorcycles with the 150 × 87 × 95 mm format without any modifications: the same 6 Ah capacity and the same terminal layout (positive on the left).
- 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.

The compatibility list also includes models from Daelim, Peugeot, Benzhou, Aprilia Motorcycles, MBK, Honda, Keeway and Sachs. Not sure whether it is the right one for your bike? Check in seconds by entering your **registration** in our finder.

### Format and fitting of the Varta YTX7A-4

The Varta YTX7A-4 is made in the 150 × 87 × 95 mm format. 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. 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 YTX7A-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 pair 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 forms part of the new **Powersports AGM Active** series.*

### 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.
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'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 YTX7A-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 YTX7A-4 model AGM? What does this technology offer?

Yes. The YTX7A-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 do I fit the YTX7A-4 model in my motorcycle?

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.

### What is the service life of the YTX7A-4 model?

Expected lifespan of the Varta YTX7A-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 are the dimensions of the Varta YTX7A-4 battery?

Dimensions (length × width × height) are 150×87×95 mm — also written as 150x87x95 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 YTX7A-4 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 YTX7A-4 fits 148 verified vehicle versions in our database.

### Which batteries are equivalent to the Varta YTX7A-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.
