## Description

## Varta G1 ProMotive SLI (formerly ProMotive HD) 90Ah 540A 12V Lorry Battery

12*V* Voltage
90*Ah* Capacity
540*A* Cold cranking
25.2*kg* Weight

The **Varta G1 lorry battery** is the **12 V**, **90 Ah** model delivering **540 A** of cold cranking power (EN), from Varta's **ProMotive SLI (formerly ProMotive HD)** range, designed for lorries, buses, large vans and machinery. Its 347 × 173 × 234 mm dimensions and positive terminal on the right make it the exact replacement for the 90 Ah battery fitted as standard in many lorries.
- Dependable through repeated starts and while powering cab equipment.
- Reinforced grids and casing for the severe demands of haulage.
- Withstands the vibration of thousands of kilometres on the road.
- High cranking current for large-capacity diesel engines.

### Applications of the Varta G1 battery

With 90 Ah, the Varta G1 is sized for lorries, buses, large vans and machinery, as a direct replacement for the original battery. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 25.2 kg and has terminal 1 and a B00 hold-down.

### Format and fitting of the Varta G1

In format, the Varta G1 measures 347 × 173 × 234 mm (length × width × height) and weighs 25.2 kg. The positive terminal on the right determines which side the cables end up on: this is the detail behind more wrong purchases than any other, so it is worth checking before you order. It takes a B00 hold-down and terminal 1, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space left by the current battery must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down would have to change.

### The Varta G1 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 high cold cranking current and a construction designed for the severe demands of heavy haulage.
It is the reliable 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 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 working long shifts. *This battery used to belong to Varta's **ProMotive HD** or **ProMotive SHD** range; following the brand's commercial renaming (2025), it now forms part of the new **ProMotive SLI** series.*

### Why choose a Varta battery

Varta is a byword for reliability: original equipment in a great many 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 it.
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 G1 battery comes with the **official manufacturer warranty**. An important warning for commercial vehicles: most lorries run **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 — and that imbalance means one overcharges while the other falls short, shortens the life of the new unit and may be treated by the manufacturer as improper use, **voiding 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 what shortens a battery's 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 downtime caused by a battery that will not start the engine.

## Frequently asked questions

### How is the Varta G1 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 right 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 G1 model?

Expected lifespan of the Varta G1 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 G1 model?

Dimensions (length × width × height) are 347×173×234 mm — also written as 347x173x234 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 G1 model?

Polarity: positive on the right. 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.

### Will the Varta G1 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 G1 fits 3 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.
