Varta N9 · Truck battery 12V 225Ah 1150A

Varta N9 ProMotive SLI (formerly ProMotive HD) 225Ah 1150A 12V Lorry Battery

The Varta N9 lorry battery is the 12 V, 225 Ah model delivering 1150 A of cold cranking power (EN) from Varta's ProMotive SLI (formerly ProMotive HD) range, designed for lorries, buses, large vans and machinery. Measuring 518 × 276 × 242 mm and with the positive terminal on the left, it is the direct replacement for lorries that leave the factory with a 225 Ah battery in this format.

In short: the Varta N9 (225 Ah, 1150 A, 518 × 276 × 242 mm, positive terminal on the left). Verified equivalent alternatives: Exide EG2253 and Tudor TG2253.

• 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 N9 battery

The Varta N9 is compatible with more than 462 vehicles: it is fitted as standard or as a replacement by brands such as Volvo, Scania, Iveco, Mercedes-Benz, DAF and MAN. For anyone who needs to change the battery in their Volvo or Scania, this Varta N9 reproduces the original specifications. It also appears as a replacement in vehicles from BMC, Fap, Renault, Leyland, Ginaf, Dennis, Steyr and Tatra, among other manufacturers.

Size and fitting of the Varta N9

In terms of format, the Varta N9 measures 518 × 276 × 242 mm (length × width × height) and weighs 62 kg. 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 B00 hold-down and a type 1 terminal, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space your current battery occupies must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will have to change.

The Varta N9 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 a high cold cranking current and a construction designed for the severe demands of heavy haulage.

It is the dependable 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 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

Varta is a byword for reliability: original equipment in numerous European vehicles and one of the most proven brands on the market. Replacing your battery with a Varta restores OEM quality — the same performance as the factory-fitted unit — with the manufacturer's backing.

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.

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 N9 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.
