When choosing a car battery in Malaysia, lead-acid batteries and lithium-ion batteries are the two mainstream technologies, each with its applicable scenarios. Lead-acid batteries dominate the market due to their cost-effectiveness and mature technology, being particularly suitable for SLI (Starting, Lighting, Ignition) systems in traditional fuel vehicles. Their advantages include high power output and low cost. For example, 12V products from brands like GS Yuasa and Deka AGM are widely used in motorcycles and four-wheeled vehicles. While lithium-ion batteries are more expensive, they offer higher energy density, faster charging, and longer lifespan, making them better suited for electric vehicles or high-end models. For instance, the lithium iron phosphate battery in the Perodua QV-E delivers a range of 445km and can reach 50% charge in 30 minutes with fast charging. For conventional fuel vehicle users, lead-acid batteries remain an economical choice, whereas electric vehicle users or those seeking high performance may opt for lithium-ion batteries. With government initiatives promoting electrification and declining lithium battery technology costs, their market share may grow. However, lead-acid batteries currently maintain advantages in serviceability and compatibility.
