## Description

## Varta M9 ProMotive SLI (formerly ProMotive HD) 170Ah 1000A 12V Lorry Battery

12*V* Voltage
170*Ah* Capacity
1000*A* Cold cranking
45,1*kg* Weight

The **Varta M9 lorry battery** is the **12 V**, **170 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. Measuring 513 × 223 × 223 mm and with the positive terminal on the left, it is the direct replacement for lorries that leave the factory with a 170 Ah battery in this format.
- Reliability through repeated starts and when powering cab equipment.
- Reinforced grids and casing for the severe demands of haulage.
- Tolerance of the vibration of thousands of kilometres on the road.
- High cranking current for large-capacity diesel engines.

### Vehicles compatible with the Varta M9 battery

According to our database, the Varta M9 is fitted to more than 494 vehicles from brands such as Fiat, Case, Fendt, Carraro, Valmet and Valtra, among others. It is a go-to option when you need a **Fiat battery**, a Case one or any other model built around this same format. The compatibility list also includes models from Zetor, Same, Case International, Lamborghini, Steyr, Hurlimann, Volvo and Bolinders - Volvo.

### Size and fitting of the Varta M9

The Varta M9 is made in the 513 × 223 × 223 mm format and weighs 45,1 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 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 M9 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

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 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 M9 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.

## Frequently asked questions

### How is the Varta M9 battery installed in the vehicle?

In most trucks it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — with positive on the left match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### What is the service life of the M9 model?

Expected lifespan of the Varta M9 is 4 to 6 years in regular truck use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What are the dimensions of the Varta M9 battery?

Dimensions (length × width × height) are 513×223×223 mm — also written as 513x223x223 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### On which side is the positive of the M9 model?

Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

### Is the M9 valid for my vehicle?

Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The M9 fits 290 verified vehicle versions in our database.

### Which batteries are equivalent to the Varta M9?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop trucks. See the "Equivalents" section to view recommended options at the same performance level.
