What is the lifespan of the hybrid battery in a Corolla?

[Josie]

The lifespan of the hybrid battery in the FAW Toyota Corolla Hybrid is 20 years. The battery requires regular cleaning: Use a damp cloth to wipe the exterior of the battery, removing dust, oil stains, white powder, and other contaminants that may cause leakage from the panel and terminals (positive and negative poles). Regular cleaning prevents the accumulation of white acidic corrosion powder on the terminals, thereby extending the battery's lifespan. Battery inspection: Focus on two key metrics: voltage and starting current. It is best to perform the inspection when the vehicle is cold (overnight is ideal). The voltage must be above 12V; if it falls below 12V, replacement is necessary. As for the starting current, under normal circumstances, it does not decrease with the battery's lifespan. Therefore, as long as the cold voltage remains above 12V, there is no significant impact on vehicle usage.
