The Exide Mileage 60B24L SMF is the 2026 premium "Red Range" iteration of Exide’s maintenance-free batteries. While the standard Exide SMF is a reliable workhorse, the Mileage series is specifically engineered for high-usage vehicles (like private-hire cars or high-mileage commuters) and features a more robust internal grid structure to survive Singapore's extreme engine bay temperatures.
