Varta LFS105M Professional Starter 105Ah 800A 12V Battery

The Varta LFS105M battery is the 12 V, 105 Ah model delivering 800 A of cold cranking power (EN), from Varta's Professional Starter from Varta, designed for starting marine engines and recreational vehicles in demanding conditions. With dimensions of 330 × 172 × 240 mm, it is the direct replacement for vehicles fitted from the factory with a 105 Ah battery in this format.

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

Applications of the Varta LFS105M battery

The Varta LFS105M covers the needs of starting marine engines and recreational vehicles in demanding conditions with 105 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 has a B01 hold-down.

Format and fitting of the Varta LFS105M

Its outer dimensions are 330 × 172 × 240 mm. It uses a B01 hold-down, the system that anchors it to the vehicle's battery tray. Before replacing it, measure the space your current battery occupies: if it matches on all three dimensions and on terminal position, the swap is direct and needs no adapters.

The Varta LFS105M 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 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 labels cannot always promise.

Manufacturer's warranty

The Varta LFS105M 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.
