The most common type of car battery in Malaysia is the lead-acid battery, particularly the 12V SLI (Starting, Lighting, Ignition) battery. This type of battery dominates the market due to its high cost-performance ratio, stable high-current output capability, and mature recycling system. Mainstream brands such as Unified Battery and GP Battery (a subsidiary of GPA Holdings) have become consumers' preferred choice owing to their long lifespan and low-maintenance characteristics. Lead-acid batteries demonstrate significant adaptability advantages in traditional internal combustion engine vehicles, with their technology being optimized for tropical climates-featuring enhanced vibration-resistant designs and heat-resistant electrolyte formulations. Notably, while the development of electric vehicles has led to a gradual increase in the adoption rate of lithium-ion batteries in premium models, lead-acid batteries currently maintain approximately 60% of the automotive battery market share. Their prices typically range from 200 to 600 Malaysian Ringgit, depending on capacity and brand premium. Consumers are advised to regularly check the electrolyte level and maintain clean terminals to prolong battery life.
