Varta LFS120 Professional Starter 120Ah 780A 12V Battery

The Varta LFS120 battery is the 12 V, 120 Ah model delivering 780 A of cold cranking power (EN), from Varta's Professional Starter range, designed for starting marine engines and recreational vehicles in demanding conditions. It replaces the original battery in vehicles with the 349 × 175 × 236 mm format without any modifications: the same 120 Ah capacity and the same terminal layout (positive on the left).

• Reliable starting of marine engines and recreational vehicles, in the cold too.
• Direct replacement for the original starter battery in boating and leisure use.
• Optimised for starting in demanding conditions: maximum power at the moment of cranking.
• Rugged construction, resistant to vibration and to the marine environment.

Applications of the Varta LFS120 battery

With 120 Ah, the Varta LFS120 is sized for starting marine engines and recreational vehicles in demanding conditions, as a direct replacement for the original battery. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 30.91 kg and has a B00 hold-down.

Format and fitting of the Varta LFS120

In terms of format, the Varta LFS120 measures 349 × 175 × 236 mm (length × width × height) and weighs 30.91 kg. The positive terminal on the left 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 LFS120 and the Professional Starter range

The Professional Starter range consists of pure starter batteries for leisure and boating, built to give marine engines and recreational vehicles powerful, reliable starting.

Unlike cycling or dual-purpose batteries, they are optimised for starting rather than for powering equipment over long periods: the choice when all you need is to fire up the engine with confidence.

Their construction prioritises peak current and resistance to the marine environment (vibration, damp and salt) rather than the ability to run equipment for hours: that is what the deep-cycle and dual-purpose ranges are for.

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 application coverage spanning practically the entire European fleet, from the city car 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 is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand labels cannot always promise.

Manufacturer's warranty

The Varta LFS120 battery comes with the official manufacturer warranty.

Care and maintenance

In leisure applications, avoiding discharges below 50% of capacity multiplies the number of cycles the battery will deliver. A suitable charger and, where possible, a solar regulator keep it healthy through the quieter seasons. To extend its life, recharge it as soon as possible after each discharge and never leave it flat over the winter. A trickle charger is the best investment for getting many cycles out of it.
