Varta M10 · Truck battery 12V 190Ah 1200A

Varta M10 ProMotive SLI (formerly ProMotive HD) 190Ah 1200A 12V Lorry Battery

The Varta M10 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. It replaces the original battery in lorries with the 513 × 223 × 223 mm format without any modifications: the same 190 Ah capacity and the same terminal layout (positive on the right).

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

Vehicles compatible with the Varta M10 battery

According to our database, the Varta M10 is fitted to more than 119 vehicles from brands such as Fiat, Allis-Chalmers, Challenger, International-Harvester, Ama and Benati, among others. It is a go-to option when you need a Fiat battery, an Allis-Chalmers one or any other model built around this same format. The compatibility list also includes models from Agrifill Toselli, Case, P&h, New Holland, Caterpillar, Bröyt, Hough and åkerman-Volvo.

Size and fitting of the Varta M10

The Varta M10 is made in the 513 × 223 × 223 mm format and weighs 44,99 kg. 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 B03 hold-down and a type 1 terminal, 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 M10 and the ProMotive SLI range

The ProMotive SLI range is Varta's starter line for industrial vehicles — lorries, buses and machinery — which in the new portfolio unifies the former ProMotive HD (Heavy Duty) and SHD (Super Heavy Duty). It offers a high cranking current for large-capacity diesel engines and a reinforced construction.

Its reinforced grids and separators cope with the vibration and cycling of long-distance haulage and of the most severe use, aiming for maximum service life and starting reliability in fleets that work long hours.

Compared with a passenger-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 putting in long days. 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

When a workshop recommends Varta it is not down to marketing: it is one of the brands with the lowest return rates in the sector, with an application coverage spanning practically the whole European vehicle parc, from the city car to the industrial vehicle.

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 M10 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.
