The “B MF M27” code helps users make the right choice in terms of technical compatibility such as case type and connection layout.
Its grey-colored case provides clear identification and emphasizes its position within the brand’s heavy-duty product group.
This battery is particularly suitable for:
Long-route commercial vehicles or heavy-duty vehicles
Vehicles with intensive service and electrical equipment
Systems with frequent stop-start operation and high cranking demand
Fleet managers or businesses looking to reduce maintenance workload
