Varta J10 · Truck battery 12V 130Ah 1000A

Varta J10 ProMotive SLI (formerly ProMotive HD) 130Ah 1000A 12V Lorry Battery

The Varta J10 lorry battery is the 12 V, 130 Ah model delivering 1000 A of cold cranking power (EN), from Varta's ProMotive SLI (formerly ProMotive HD) range, designed for lorries, buses, large vans and machinery. It replaces the original battery in lorries with the 514 × 175 × 210 mm format without any modifications: the same 130 Ah capacity and the same terminal layout (positive on the left).

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

Vehicles compatible with the Varta J10 battery

The Varta J10 is compatible with more than 557 vehicles: it is fitted as standard or as a replacement by makes such as Fendt, Fiat, John Deere, Massey Ferguson, Claas and Fiatallis. For anyone who needs to change the battery in their Fendt or Fiat, this Varta J10 reproduces the original specifications. Added to that list are models from Volvo, Liebherr, International-Harvester, Zetor, Case, Khd, Sperry New Holland and Komatsu. It has been cross-checked against 17 original equipment references from different manufacturers.

Format and fitting of the Varta J10

In format, the Varta J10 measures 514 × 175 × 210 mm (length × width × height) and weighs 35.46 kg. The positive terminal on the left 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 B03 hold-down and terminal 1, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space left by the current battery must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down would have to change.

The Varta J10 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.

Compared with a car battery, this range is calibrated for severe, continuous use: greater mechanical strength and more tolerance of cycling and of the knocks of the road. It is the correct replacement for a lorry, bus or machine working long shifts. 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

Varta is an original equipment (OEM) supplier to a good share of Europe's car manufacturers: many cars leave the factory with a Varta fitted. Buying a replacement means, in most cases, refitting the original battery with the same quality and the brand's official warranty.

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 J10 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.
