For caravans, motorhomes, and boats, this translates to enhanced reliability and performance. VARTA Professional Li-Ion batteries are designed for leisure settings to power essential onboard devices that ensure both essential functions and increased comfort, even during extended trips.
Conventional leisure batteries like VARTA Professional SLI are primarily designed for starting engines, while VARTA Professional AGM and VARTA Professional EFB batteries provide both starting power and energy supply for onboard systems. In contrast, VARTA Professional Li-Ion batteries focus exclusively on delivering reliable and efficient energy supplies for leisure applications.


Li-Ion batteries offer high depth of discharge and superior durability compared to lead-acid battery technology, providing a longer lifetime, although AGM batteries remain sufficient for most applications. This results in a significantly longer cycle life, making them a cost-effective choice over time.
Whether in freezing temperatures, daily comfort use, or long off-grid trips, mobile energy systems today must deliver more than ever.
This section explains how modern Li-Ion battery technology offers greater efficiency, safety, and durability, and how VARTA’s Professional Li-Ion battery performs reliably in real-life applications from cell chemistry to smart energy management.
VARTA’s Professional Li-Ion batteries are built using only Grade A prismatic LFP cells, ensuring consistent capacity, low internal resistance, and efficient energy delivery in both mobile and off-grid power systems. This results in lower heat generation, no dendrite formation, and high operational safety. Whether for caravans, motorhomes, solar storage systems, or marine battery use, VARTA’s Professional Li-Ion battery ensures high reliability and a longer service life - making it the preferred solution for modern, maintenance-free battery systems.
In harsh climates, staying powered is critical. Whether during mountain nights or icy coastal tours, VARTA Professional Li-Ion batteries deliver dependable output, even as temperatures drop. The Li-Ion battery with the code LL100LT suits smaller energy needs, while the LL150LT Professional Li-Ion battery supports more demanding off-grid adventures.
This makes VARTA Professional Li-Ion batteries ideal for winter camping, alpine touring, or year-round off-grid use; delivering safe, consistent performance when it matters most.
Whether you’re heading into the mountains, staying off-grid at a lakeside, or simply enjoying comfort on the road, real-world travel demands reliable energy. The following examples show how VARTA Professional Li-Ion batteries support everyday situations delivering the power needed to make mobile life feel just like home.
Two travelers are on a weekend trip in the Alps, far from any campsite hookups. Each morning, they fire up their high-wattage espresso machine using only their onboard battery. Thanks to the VARTA Professional Li-Ion system, the machine delivers a full brew-hot and fast-without draining the power supply.
After swimming in a mountain lake, a traveler uses a hair dryer inside the motorhome. The high current demand is no issue for VARTA’s Professional Li-Ion, which delivers consistent performance and avoids voltage drops that could shut down conventional batteries.
During summer travels through southern Europe, the onboard air conditioning runs continuously while parked. Unlike traditional batteries, the VARTA Professional Li-Ion supports partial state of charge (PSOC) operation and recharges quickly via solar or alternator, ensuring comfort even with limited charging windows.
