Varta LL100LT · Marine battery 12.8V 100Ah Li-Ion

Varta LL100LT Professional Li-Ion Deep Cycle 100Ah 12.8V Battery

The Varta LL100LT battery is the 12.8 V, 100 Ah from the Professional Li-Ion Deep Cycle range, designed for motorhomes, boats and auxiliary power equipment. Its 278 × 175 × 190 mm dimensions and positive terminal on the right make it the exact replacement for the 100 Ah battery fitted as standard in many vehicles.

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

Applications of the Varta LL100LT battery

With 100 Ah, the Varta LL100LT 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 has a B13 hold-down.

Size and fitting of the Varta LL100LT

In format, the Varta LL100LT measures 278 × 175 × 190 mm (length × width × height). 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, 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 LL100LT and the Professional Li-Ion Deep Cycle range

The Professional Li-Ion Deep Cycle is Varta’s new lithium (LiFePO4) series for leisure and marine use: far lighter than lead, it withstands thousands of cycles and uses nearly all of its capacity in each discharge.

It is the premium choice for motorhomes and boats seeking maximum range and service life at minimum weight, with an integrated battery management system (BMS).

The chemistry is built for draining and recharging the battery many times over — the typical pattern in leisure and marine use — where an ordinary car battery would sulphate within weeks. It offers endurance for the on-board equipment and the cranking power to turn the engine over when the moment comes.

Why choose a Varta battery

Varta is a byword for reliability: original equipment in numerous European vehicles and one of the most proven brands on the market. Replacing your battery with a Varta restores OEM quality — the same performance as the factory-fitted unit — with the manufacturer's backing.

Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year.

Varta production combines automated lines with checks on 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 LL100LT 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.
