Varta LFS105N Professional Dual Purpose 105Ah 800A 12V Battery

The Varta LFS105N battery is the 12 V, 105 Ah model delivering 800 A of cold cranking power (EN) from Varta's Professional Dual Purpose range, designed for motorhomes, boats and auxiliary power equipment. It replaces the original battery in vehicles with the 330 × 175 × 240 mm format without any modifications: the same 105 Ah capacity.

• Ideal for motorhomes, marine use and domestic power on board.
• Dual cycle: it both cranks the engine and powers auxiliary equipment.
• More endurance on board than a conventional starter battery.
• Tolerates deep discharges and repeated recharging without degrading.

Applications of the Varta LFS105N battery

With 105 Ah, the Varta LFS105N is sized for motorhomes, boats and auxiliary power equipment, as a direct replacement for the original battery. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 26,9 kg and has a type 1 terminal and a B00 hold-down.

Size and fitting of the Varta LFS105N

The Varta LFS105N is made in the 330 × 175 × 240 mm format and weighs 26,9 kg. It uses a B00 hold-down and a type 1 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 Varta LFS105N and the Professional Dual Purpose range

The Professional Dual Purpose range consists of dual-purpose batteries: they serve both to crank the engine and to power the on-board services, a balance conceived for leisure and marine use.

They are the answer when you want a single battery that starts reliably and at the same time sustains equipment draw with the engine off, without going as far as the extreme cycling of a deep cycle unit.

Unlike a pure starter battery, this range tolerates deep discharges and repeated recharging without degrading: exactly what a motorhome or a boat that draws power with the engine off needs. It therefore combines cranking and domestic duty in a single dual-cycle battery.

Why choose a Varta battery

Manufactured by Clarios to German standards, Varta is one of the world's benchmark brands in starter batteries and an OEM supplier to the leading car makers. Choosing it as a replacement guarantees specifications equal to or better than the originals.

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's production combines automated lines with verification of more than 100 parameters per unit; that traceability is what underpins its reputation for reliable starting throughout the battery's life.

Manufacturer's warranty

The Varta LFS105N 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 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.
