## Description

## Varta D33 ProMotive SLI (formerly ProMotive HD) 66Ah 510A 12V Lorry Battery

12*V* Voltage
66*Ah* Capacity
510*A* Cold cranking
16,80*kg* Weight

The **Varta D33 lorry battery** is the **12 V**, **66 Ah** model with **510 A** of cold cranking power (EN) from Varta's **ProMotive SLI (formerly ProMotive HD)** range, intended for lorries, buses, large vans and machinery. It replaces the original battery with no modifications in lorries using the 278 × 175 × 190 mm format: the same 66 Ah capacity and the same terminal layout (positive on the right).
- Tolerance of the vibration of thousands of kilometres on the road.
- High cranking current for large-displacement diesel engines.
- Reliability through repeated starts and while powering cab equipment.
- Reinforced grids and casing for the harsh demands of haulage.

### Vehicles compatible with the Varta D33 battery

This battery is listed as compatible with more than 53 vehicles from manufacturers such as Carraro, Belarus, Antonio Carraro, Atlas, John Deere and Huerlimann. For anyone who needs to change the **battery in their Carraro** or Belarus, this Varta D33 reproduces the original specifications. Added to that list are models from Fendt, Sullair, Case, Büscher, Clayson, Hinomoto, RAMmax and Ama.

### Format and fitting of the Varta D33

The Varta D33 is made in the 278 × 175 × 190 mm format and weighs 16,80 kg. The positive terminal on the right 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 B13 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 D33 and the ProMotive SLI range

The **ProMotive SLI** series is Varta's starter line for professional transport, bringing the former ProMotive HD and SHD together under a single name. It is built to crank large-displacement diesel engines and to take the daily punishment of the lorry, the bus and construction machinery.
The key to this range is sheer sturdiness: reinforced plates and fixings that stand up to thousands of kilometres of vibration and to deep discharge cycles, keeping fleet downtime from starting failures to a minimum.
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. *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

A good share of the vehicles on Europe's roads left the factory with a Varta fitted: the brand has spent decades supplying the assembly lines of the leading car groups. Replacing with Varta means, in practice, giving the vehicle back the battery the manufacturer had in mind.
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 is Europe's leading maker of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand makes cannot always promise.

### Manufacturer's warranty

The Varta D33 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

### How is the Varta D33 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 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 D33 model?

Expected lifespan of the Varta D33 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 measurements of the D33 model?

Dimensions (length × width × height) are 278×175×190 mm — also written as 278x175x190 mm and correspond to the European L3 case size — 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.

### Does this 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 D33 fits 28 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.
