Varta H4 · Truck battery 12V 100Ah 600A

Varta H4 ProMotive SLI (formerly ProMotive HD) 100Ah 600A 12V Lorry Battery

The Varta H4 lorry battery is the 12 V, 100 Ah model delivering 600 A of cold cranking power (EN), from Varta's ProMotive SLI (formerly ProMotive HD) range, designed for lorries, buses, large vans and machinery. Measuring 413 × 175 × 220 mm with the positive terminal on the left, it is the direct replacement for lorries that leave the factory with a 100 Ah battery in this format.

• 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.

Vehicles compatible with the Varta H4 battery

The Varta H4 is compatible with more than 33 vehicles: it is fitted as standard or as a replacement by makes such as Iseki, International-Harvester, Ford, Kobelco, Nissan and Kubota. For anyone who needs to change the battery in their Iseki or International-Harvester, this Varta H4 reproduces the original specifications. It also appears as a replacement in vehicles from Moll, Desta, Moroka, Tata and Ashok Leyland, among other manufacturers.

Format and fitting of the Varta H4

The Varta H4 is made in the 413 × 175 × 220 mm format and weighs 27.43 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 B00 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 H4 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

A good share of the vehicles on Europe's roads left the factory with a Varta fitted: the brand has been supplying the assembly lines of the major car groups for decades. Replacing with a Varta means, in practice, giving the vehicle back the battery its manufacturer had specified.

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.

More than 100 manufacturing parameters are checked on every Varta battery before it leaves the plant, a level of rigour that explains why so many workshops and manufacturers trust the brand as their first-choice replacement.

Manufacturer's warranty

The Varta H4 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.
