The rising automotive production is expected to fuel the growth of the starting, lighting, and ignition (SLI) battery market. Automotive production refers to the entire process of designing, manufacturing, and assembling vehicles, including cars, trucks, and motorcycles. This production is on the rise as growing consumer demand for personal vehicles prompts manufacturers to ramp up output to meet market needs efficiently. SLI batteries are essential in this process, ensuring the reliable functioning of starting, lighting, and ignition systems in vehicles, while their consistent performance enhances vehicle efficiency and minimizes downtime, contributing to smoother manufacturing and operation. For instance, in March 2024, the European Automobile Manufacturers' Association (ACEA) reported that global car production reached around 76 million units in 2023, reflecting a significant 10.2% increase compared to the previous year. This growth in automotive production is directly driving demand for SLI batteries.

Companies in the SLI battery market are focusing on advancing high-performance automotive batteries to meet the increasing demand for efficient energy storage solutions. Starting power car batteries are designed to provide a strong surge of current to ensure rapid engine ignition, delivering dependable starting performance while also supporting the vehicle's electrical systems. For example, in July 2024, Exide Industries Ltd., an India-based battery manufacturer, introduced advanced Absorbent Glass Mat (SLI-AGM) batteries for cars. These batteries are engineered to offer higher starting power, longer lifespan, and improved reliability across all driving conditions. They feature superior vibration resistance, faster recharge capability, and enhanced cold-start performance, and are designed to be maintenance-free, providing consistent power even in extreme conditions.

In April 2022, Gridtential Energy, a U.S.-based provider of Silicon Joule bipole battery technology, partnered with Camel Energy to advance automotive innovation with sustainable, high-performance silicon hybrid batteries. This collaboration aims to develop advanced start-stop batteries for internal combustion, low-voltage electric, and mild-hybrid vehicles. Utilizing Gridtential’s Silicon Joule technology, the batteries will offer higher power, lighter weight, improved charge acceptance, and longer lifespan compared to traditional batteries. Camel Energy, based in the U.S., specializes in manufacturing SLI batteries.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid rise in U.S. tariffs and the subsequent trade frictions in spring 2025 are having a major impact on the electrical and electronics sector, with semiconductors, display panels, and rare-earth metals (essential for batteries and motors) subject to steep duties. Consumer electronics brands face profit erosion, as competitive markets limit their ability to pass costs to buyers. Industrial electronics manufacturers, meanwhile, grapple with delayed projects due to shortages of tariff-impacted components like printed circuit boards. Companies are responding by relocating assembly to tariff-exempt countries, increasing inventory buffers, and redesigning products to reduce dependency on restricted materials.
