The battery life of 48V mild hybrid systems is typically 3 to 5 years, which can be extended to over 5 years with proper use and maintenance. For some luxury brand models, the battery life can even approach the lifespan of the entire vehicle. In contrast, the battery life of traditional hybrid models (such as the Toyota Camry Hybrid or Honda Accord Hybrid) generally ranges from 8 to 15 years, depending on the battery type, driving habits, and environmental conditions. Nickel-metal hydride batteries in hybrid vehicles usually last 8 to 15 years, while lithium-ion batteries can last 10 to 20 years. However, the actual lifespan is significantly affected by charging and discharging strategies (shallow charging and discharging can extend life), thermal management systems (liquid cooling is superior to air cooling), and extreme temperatures. For example, high-temperature environments will accelerate capacity degradation. Regarding replacement costs, the mainstream price range for 48V mild hybrid batteries is 8,000 to 30,000 Malaysian Ringgit, with higher prices for luxury brand models. The replacement cost of traditional hybrid batteries is approximately 3,000 to 5,000 US dollars (equivalent to about 14,000 to 23,000 Malaysian Ringgit). Brands like Toyota also offer warranties of up to 10 years or 240,000 kilometers. It is recommended to replace batteries through official channels to ensure compatibility and perform regular maintenance to optimize battery performance, such as avoiding frequent short-distance starts/stops or parking in high-temperature environments.
