Varta LFS52 Professional Starter 52Ah 470A 12V Battery

The Varta LFS52 battery is the 12 V, 52 Ah model delivering 470 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 207 × 175 × 190 mm format without any modifications: the same 52 Ah capacity and the same terminal layout (positive on the right).

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

Applications of the Varta LFS52 battery

With 52 Ah, the Varta LFS52 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 12,400 kg and has a type 1 terminal and a B13 hold-down.

Size and fitting of the Varta LFS52

The Varta LFS52 is made in the 207 × 175 × 190 mm format and weighs 12,400 kg. The positive terminal on the right 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 B13 hold-down and a type 1 terminal, 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 LFS52 and the Professional Starter range

The Professional Starter range consists of pure starter batteries for leisure and marine use, built to give marine engines and recreational vehicles a powerful, dependable start.

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

Unlike deep-cycle or dual-purpose batteries, this range is optimised for one thing only: delivering all its power at the moment of cranking, even with a cold engine or after a season moored up.

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 seasons when it sees less use. 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.
