Varta F6 Dynamic SLI · Car battery 90Ah 720A

Varta F6 Dynamic SLI (formerly Black Dynamic) 90Ah 720A 12V Car Battery

The Varta F6 car battery is the 12 V, 90 Ah model delivering 720 A of cold cranking power (EN), from Varta's Dynamic SLI (formerly Black Dynamic) range, designed for cars with conventional starting, without a Start-Stop system. Measuring 353 × 175 × 190 mm with the positive terminal on the right, it is the direct replacement for cars that leave the factory with a 90 Ah battery in this format.

In short: the Varta F6 (90 Ah, 720 A, 353 × 175 × 190 mm, positive terminal on the right). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size. Verified equivalent alternatives: Exide EC900 and Tudor TC900.

• Long service life with normal use and a charging system in good order.
• Maintenance-free lead-acid technology: no topping up with water.
• Direct replacement for the original battery in cars without Start-Stop.
• Reliable cold starting thanks to its high cranking current.

Format and fitting of the Varta F6

The Varta F6 is made in the 353 × 175 × 190 mm format and weighs 21.1 kg. The positive terminal on the right determines which side the cables end up on: this is the detail behind more wrong purchases than any other, so it is worth checking before you order. It takes a B13 hold-down and terminal 1, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Varta F6 and the Dynamic SLI range

The Dynamic SLI series (blue label) is Varta's lead-acid line for cars with conventional starting, without Start-Stop. It succeeds the Blue, Silver and Dynamic SLI ranges and keeps the calcium-silver grid technology that ensures low self-discharge and reliable cold starting, with no maintenance required.

Aimed at the bulk of the car and van fleet, it offers Varta's classic balance of starting power and durability at a sensible price: the logical replacement for the original battery in a car without Start-Stop.

This series uses lead-acid technology with plates optimised for a good balance between starting power and service life. It is the natural replacement when your car has no Start-Stop and came with a standard battery from the factory: the same thinking, without paying over the odds for a chemistry you do not need. This battery used to belong to Varta's Dynamic SLI, Dynamic SLI or Dynamic SLI range; following the brand's commercial renaming (2025), it now forms part of the new Dynamic SLI series.

Why choose a Varta battery

When a workshop recommends Varta it is not doing so out of marketing: it is one of the brands with the lowest return rates in the sector, and its application coverage takes in practically the whole European fleet, from the small hatchback to the commercial vehicle.

Varta combines more than a century of experience with Clarios's industrial production: it is the battery many manufacturers choose as standard and one of the most recommended by workshops. Like any lead-acid battery, it is 100% recyclable.

Varta is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand makes cannot always promise.

Manufacturer's warranty

The Varta F6 battery comes with the official manufacturer warranty.

Care and maintenance

To get the most out of it, keep the alternator in good order and avoid leaving lights or accessories on with the engine switched off. Repeated very short journeys are its worst enemy: they stop the battery from recharging fully and shorten its life. If the car is going to stand for weeks, it is worth disconnecting a terminal or fitting a trickle charger so that it does not discharge below the safe threshold. Checking that the terminals are clean and properly tightened also helps it start first time.
