- Reliability through repeated starts and while powering cab equipment.
- Reinforced grids and casing for the harsh demands of haulage.

### Vehicles compatible with the Varta C40 battery

This battery is listed as compatible with more than 388 vehicles from manufacturers such as Volvo, Mercedes-Benz, Scania, Iveco, DAF and MAN. If you are after a **battery for a Volvo** or Mercedes-Benz in these dimensions, the C40 is one of the usual replacement references. It also appears as a replacement in vehicles from BMC, Fap, Leyland, Renault, Ginaf, Dennis, Steyr and Tatra, among other manufacturers.

### Format and fitting of the Varta C40

The Varta C40 is made in the 518 × 276 × 242 mm format and weighs 57,96 kg. The positive terminal on the left determines which side the cables end up on: it is the detail that causes the most buying mistakes, so it is worth checking before you order. It uses 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 error when replacing a battery.

### The Varta C40 and the ProMotive EFB range

The **ProMotive EFB** range uses reinforced EFB technology for commercial transport with frequent starts and a heavy electrical draw. It stands up to the cycling of professional use far better than a conventional battery.
It is the middle-ground solution for lorries and large vans: more durability than standard lead without the cost of AGM, ideal for delivery work and routes with plenty of stops.
A commercial vehicle demands a high cranking current and endurance against the vibration of thousands of kilometres. This series uses reinforced grids and rugged construction to cope with repeated starts of large diesel engines and with the draw of auxiliary cab equipment.

### Why choose a Varta battery

Choosing Varta means sticking with the reference the vehicle manufacturer itself approved in the first place. Against own-brand batteries, the difference is not in the purchase price but in how many winters the battery lasts before leaving you stranded.
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.
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 C40 battery comes with the **official manufacturer warranty**. One important warning for commercial vehicles: most lorries carry **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; that imbalance means one is overcharged while the other falls short, it 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, periodically checking the state of charge and the battery hold-down prevents breakdowns out on the road. Vibration and the high temperatures of the engine bay are the factors that shorten its 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 stoppages caused by a failure to start.

## Frequently asked questions

### Is the C40 model EFB? Which trucks need it?

Yes. The C40 is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. Withstands more cycles than a conventional but fewer than an AGM. Fitted to trucks with basic Start-Stop (no regenerative braking). More affordable than an equivalent AGM, lifespan 4-6 years.

### Is the Varta C40 battery suitable for Start-Stop?

Yes. As EFB technology it is designed for Start-Stop vehicles. EFB batteries cover basic Start-Stop (no regenerative braking). EFB is recommended for basic Start-Stop; AGM is recommended when regenerative braking is also present, thanks to its higher cycle capability. It works straight out of the box — on most modern vehicles registering the battery via OBD is recommended so the alternator automatically applies the optimal charging profile.

### How do I change this battery step by step?

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 this page. 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 — 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 C40 model?

Expected lifespan of the Varta C40 is 4 to 6 years in basic Start-Stop truck use. 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 measurements of the C40 model?

Dimensions (length × width × height) are 518×276×242 mm — also written as 518x276x242 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.

### Will the Varta C40 battery fit my truck?

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 C40 fits 320 verified vehicle versions in our database.

### Which interchangeable batteries are there for this one?

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.

### What exactly is an EFB battery like the Varta C40?

An EFB (Enhanced Flooded Battery) is a flooded lead-acid battery reinforced with plate additives (carbon and polyethylene) and thicker grids. It withstands twice the cycles of a conventional battery and handles deep discharges better, but less than an AGM. It is the original fitment on trucks with basic Start-Stop (no regenerative braking): Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG, Ford EcoBoost. If your truck came with EFB from the factory, this is the correct battery — upgrading to AGM is optional (marginal improvement). If it came with AGM, EFB may fall short: better fit AGM. The Varta C40 is original and meets EN 50342-6.

### Do I need to register the Varta C40 on the truck after installation?

On most trucks it is not strictly necessary — the alternator detects the new battery and adapts the charge automatically. It is recommended to register the battery via OBD so that the alternator applies the optimal charging profile from the first minute and extends the battery life as much as possible (especially on brands with sophisticated BMS: BMW, Mercedes, Audi, Volvo, Land Rover). Any workshop with an OBD scanner (~10-15 € labour) does it in 5 minutes. DIY apps: VCDS / Carista (VAG), Bimmercode (BMW), iCarsoft. If you do not register, the truck will still start correctly — the alternator just takes a few days to adjust the profile. The Varta C40 ships factory-charged at 80-90% so you can use it straight after fitting.
