## Description

ProMotive SLI is the starting range for industrial vehicles: truck, bus, tractor and machinery. It groups what was previously sold as ProMotive HD and ProMotive SHD.

## Technology

They are built to withstand the continuous vibration of heavy transport: plates anchored with resin, reinforced grid and casing prepared for severe work. The capacity and starting current are much higher than those of a passenger car, because a large displacement diesel engine requires a much higher starting torque, especially in cold weather.

## Applications

- Long-haul trucks and tractor units
- Buses and coaches
- Tractors and agricultural machinery
- Public works machinery and special vehicles

## The range in figures

References 32
Capacity 45 – 225 Ah
Cold cranking 300 – 1400 A (EN)
Voltage 12 V
Technology PLOMO/ACIDO

## How to choose

In industrial vehicles, it is common to install two batteries in series to obtain 24 V. Always replace both at the same time and with the same reference: mixing a new battery with a worn one causes the old one to drag down the new one and shortens the life of both.

## Naming and equivalences

ProMotive SLI groups what was previously sold as VARTA ProMotive HD and VARTA ProMotive SHD. It is the reference starting battery for trucks, buses, and agricultural machinery.

## Frequently asked questions

### Which range replaces the VARTA ProMotive HD and SHD?

The VARTA ProMotive SLI. Both lines were unified in the 2026 portfolio; the equivalence is established by capacity and cranking current.

### Why does a truck have two batteries?

Because the electrical system works at 24 volts and is obtained by connecting two 12 V batteries in series. Both should always be replaced at the same time and with the same reference.

### Can I install a new battery alongside an old one?

It is not recommended. In a series connection, the more worn battery limits the set and drags the new one, thus shortening the life of both.

### What distinguishes a truck battery from a car battery?

The construction against vibration —anchored plates and reinforced casing— and a much higher cranking current, necessary to start a large displacement diesel engine in cold weather.
