Varta L3 · Truck battery 12V 190Ah 1200A

Varta L3 ProMotive SLI (formerly ProMotive HD) 190Ah 1200A 12V Lorry Battery

The Varta L3 lorry battery is the 12 V, 190 Ah model delivering 1200 A of cold cranking power (EN) from Varta's ProMotive SLI (formerly ProMotive HD) range, designed for lorries, buses, large vans and machinery. Its 513 × 223 × 223 mm dimensions and positive terminal on the left make it the exact replacement for the 190 Ah battery fitted as standard in many lorries.

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

Vehicles compatible with the Varta L3 battery

This battery is listed as compatible with more than 124 vehicles from manufacturers such as Fiat, Case, Bolinders - Volvo, Huerlimann, Bröyt and Gueldner. For anyone who needs to change the battery in their Fiat or Case, this Varta L3 reproduces the original specifications. It also appears as a replacement in vehicles from Atlas, International-Harvester, Stavostroj, Bourgoin, Paget (valmet), Fortschritt, Ponsse and Utos, among other manufacturers.

Size and fitting of the Varta L3

In terms of format, the Varta L3 measures 513 × 223 × 223 mm (length × width × height). The positive terminal on the left 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 B03 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 L3 and the ProMotive SLI range

The ProMotive SLI series is Varta's starter line for professional transport, gathering the former ProMotive HD and SHD under a single name. It is built to crank large-capacity diesel engines and to take the daily punishment of lorries, buses and construction machinery.

The key to this range is ruggedness: reinforced plates and mountings that resist thousands of kilometres of vibration and deep discharge cycles, keeping fleet downtime from starting failures to a minimum.

An industrial vehicle demands a high cranking current and the stamina to shrug off the vibration of thousands of kilometres. This series uses reinforced grids and a rugged construction to handle repeated starts of large diesel engines and 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 forms part of the new ProMotive SLI series.

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 batteries are made under the Clarios group with German technology and quality controls that make them one of the best-selling choices in Europe. As a lead battery, it is 100% recyclable through any collection point.

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 L3 battery comes with the official manufacturer warranty. One important warning for industrial vehicles: most lorries carry two batteries wired 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; that imbalance leaves one overcharged and the other short, shortens the life of the new unit, and the manufacturer may treat it as misuse and void 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 the factors that shorten its life the 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 no-start.
