✅ Basic Positioning: An upgraded flooded lead-acid battery, positioned between standard MF maintenance-free batteries and AGM batteries. It is mainly designed for passenger cars with auto start-stop systems.
✅ Core Advantages
Thicker plates and upgraded paste formula for positive plates. Much better cycle resistance than ordinary lead-acid batteries, capable of handling frequent high-current loads during start-stop cycles.
Large electrolyte reserve with good heat dissipation, excellent high-temperature resistance, suitable for installation in the high-temperature engine bay.
Cost-effective, lower purchase cost than AGM start-stop batteries.
Good charge acceptance, faster to recharge than standard maintenance-free batteries.
✅ Limitations
Inferior deep-discharge resistance compared with AGM batteries. Not suitable for vehicles with long standby power consumption or heavy modified on-board electrical equipment.
Not recommended for vehicles with extremely frequent start-stop operation or hybrid vehicles.
Still a flooded-type battery. NOT to be installed upside down.
✅ Application Scenarios
Fuel vehicles equipped with factory auto start-stop systems and originally fitted with EFB batteries; start-stop vehicles exposed to high engine bay temperatures where AGM batteries are out of budget.
