## Description

## Varta N12 ProMotive SLI (formerly ProMotive HD) 200Ah 950A 6V Lorry Battery

6*V* Voltage
200*Ah* Capacity
950*A* Cold cranking
31*kg* Weight

The **Varta N12 lorry battery** is the **6 V**, **200 Ah** model delivering **950 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 403 × 175 × 238 mm format without any modifications: the same 200 Ah capacity and the same terminal layout (positive on the right).
- 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.

### Applications of the Varta N12 battery

The Varta N12 covers the needs of lorries, buses, large vans and machinery with 200 Ah of capacity and a construction built for that use. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 31 kg and has a type 20 terminal and a B11 hold-down.

### Size and fitting of the Varta N12

The Varta N12 is made in the 403 × 175 × 238 mm format and weighs 31 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 B11 hold-down and a type 20 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 N12 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.
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 N12 battery comes with **a 1-year official warranty** from the manufacturer. 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 do I verify this battery is the right one?

Three ways: 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 for the N12; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET).

### How is the Varta N12 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.

### How many months of warranty does the N12 truck model cover?

This battery includes 1 year of official manufacturer warranty against manufacturing defects. It covers internal electrical failures and abnormal capacity drops. It does NOT cover misuse (sulfation from heavy duty without proper recharge, alternator overcharge, etc.). On confirmed defect after technical inspection, we replace the N12 at no cost.

### When will I receive the N12 model?

In mainland Spain and Portugal it arrives in 24 h if you order before 17:00 and the battery is in stock — it leaves the same day and arrives the next business day. Afternoon or weekend orders ship the next business day. For Balearics, Canaries and other EU destinations, allow 2-5 days. Shipping cost is calculated in the cart based on destination and service (standard, express, cash on delivery). Tracking number is sent by email + SMS as soon as the parcel ships.

### Can I return the Varta N12 battery if it doesn't fit or doesn't work?

Yes. You have 14 days from delivery to return it. In mainland Spain and Portugal returns are FREE — we cover the return shipping cost via prepaid label. In other EU countries the return shipping cost is the customer's. It must arrive in its original packaging with no signs of installation. If it was defective, the warranty covers replacement even after the 14-day period.

### Where can I buy the Varta N12 battery?

At baterias.com — authorised distributor with real stock, 24h delivery in mainland Spain and Portugal if you order before 17:00, and full manufacturer warranty. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). Secure payment by card, Bizum, PayPal or bank transfer. If you choose at-home installation, our technician will take the used battery and dispose of it through an authorised collection point.

### What is the service life of the N12 model?

Expected lifespan of the Varta N12 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 N12 model?

Dimensions (length × width × height) are 403×175×238 mm — also written as 403x175x238 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.

### What is the weight of the N12 model?

It weighs 31 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre).

### How many amps does the Varta N12 battery have?

Nominal capacity 200 Ah[?cca: and [cold-cranking amps 950 A]] at 6 V. Ah measure the total energy available (autonomy); CCA (also written A in cold or EN under the European standard) measure the instantaneous power to crank the starter motor. A battery with more CCA starts better in winter; one with more Ah keeps accessories on for longer.

### 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 9:00–18:00 CET). The N12 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Varta N12?

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.

### Is the N12 model better than its equivalents from other brands?

This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section.
