Varta I11 ProMotive · Truck battery 6V 112Ah 510A

Varta I11 ProMotive SLI (formerly ProMotive HD) 112Ah 510A 6V Lorry Battery

The Varta I11 lorry battery is the 6 V, 112 Ah model delivering 510 A of cold cranking power (EN), from Varta's ProMotive SLI (formerly ProMotive HD) range, designed for lorries, buses, large vans and machinery. Measuring 260 × 175 × 236 mm with the positive terminal on the right, it is the direct replacement for lorries that leave the factory with a 112 Ah battery in this format.

In short: the Varta I11 (112 Ah, 510 A, 260 × 175 × 236 mm, positive terminal on the right). Verified equivalent alternatives: Varta K13 and Exide EU140-6.

• Withstands the vibration of thousands of kilometres on the road.
• High cranking current for large-capacity diesel engines.
• Dependable through repeated starts and while powering cab equipment.
• Reinforced grids and casing for the severe demands of haulage.

Applications of the Varta I11 battery

With 112 Ah, the Varta I11 is sized for lorries, buses, large vans and machinery, as a direct replacement for the original battery. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 16.500 kg and has terminal 1 and a B01 hold-down.

Format and fitting of the Varta I11

In format, the Varta I11 measures 260 × 175 × 236 mm (length × width × height) and weighs 16.500 kg. The positive terminal on the right determines which side the cables end up on: this is the detail behind more wrong purchases than any other, so it is worth checking before you order. It takes a B01 hold-down and terminal 1, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Varta I11 and the ProMotive SLI range

The ProMotive SLI is Varta's starter battery range for commercial and industrial vehicles; it consolidates the former ProMotive HD and SHD names into a single series organised by technology. It delivers high cold cranking current and a construction designed for the severe demands of heavy haulage.

It is the reliable replacement for lorries, buses, tractor units and machinery working long shifts: resistance to road vibration, tolerance of cycling and guaranteed starting even after weeks standing idle.

Commercial vehicles demand high cranking current and endurance against the vibration of thousands of kilometres. This series uses reinforced grids and a robust construction to cope with repeated starts of large diesel engines and with the draw of the cab's auxiliary equipment. This battery used to belong to Varta's ProMotive HD or ProMotive SHD range; following the brand's commercial renaming (2025), it now forms part of the new ProMotive SLI series.

Why choose a Varta battery

Choosing Varta means sticking with the reference the vehicle manufacturer itself signed off in the first place. Against own-brand batteries, the difference is not the purchase price but how many winters the battery lasts before it leaves you stranded.

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 makes cannot always promise.

Manufacturer's warranty

The Varta I11 battery comes with the official manufacturer warranty. An important warning for commercial vehicles: most lorries run two batteries connected in series (a 24 V installation). If you replace only one, the new battery ends up working alongside the old one — which has already lost capacity and has higher internal resistance — and that imbalance means one overcharges while the other falls short, shortens the life of the new unit and may be treated by the manufacturer as improper use, voiding the warranty. That is why it is always advisable to change both batteries at the same time.

Care and maintenance

In professional use, checking the state of charge and the battery hold-down regularly prevents breakdowns on the road. Vibration and the high temperatures of the engine bay are what shortens a battery's life most, so secure mounting is key. Keeping the terminals clean and tight and checking the charging system extends battery life in vehicles that clock up long hours. A well-maintained battery reduces the risk of downtime caused by a battery that will not start the engine.
