Varta B49-6 6V 8Ah 40A is a sealed motorcycle battery ready to fit, with the JIS reference your mechanic recognises at a glance. Vibration-resistant, keeps voltage during the winter off-season and cranks first time when you take it out for a ride.

The Varta B49-6 motorcycle battery (reference 008011004) is the 6 V, 8 Ah model delivering 40 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 91 × 83 × 160 mm format without any modifications: the same 8 Ah capacity and the same terminal layout (positive on the left).
The Varta B49-6 covers the needs of motorcycles, scooters, quads and personal watercraft with 8 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 1,4 kg and has a Y6 terminal and a B00 hold-down.
In terms of format, the Varta B49-6 measures 91 × 83 × 160 mm (length × width × height) and weighs 1,4 kg. The positive terminal on the left determines which side the cables run to: it is the detail that causes the most buying mistakes, so it is worth checking before ordering. It uses a B00 hold-down and a Y6 terminal, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space your current battery occupies must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will have to change.
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.
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.
Choosing Varta means going with the reference the car manufacturer itself signed off on in its day. 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 is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand makers cannot always assure.
The Varta B49-6 battery comes with the official manufacturer warranty.
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.

See all 4 compatible vehiclesGuide to replace your motorcycle battery in 10-15 minutes. Motorcycle batteries are light (2-5 kg) and usually need an 8 mm wrench.
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.
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.
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.
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
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.
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
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.
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.
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.
Expected lifespan of the Varta (B49-6) is 4 to 6 years in regular motorcycle use without 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.
Dimensions (length × width × height) are 91×83×161 mm — also written as 91x83x161 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.
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 (B49-6) fits 4 verified vehicle versions in our database.
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.
