Hermetic Extra Power Batteries

Extra powered line for fully equipped cars.

Open Parts batteries quality is guaranteed by compliance with ISO/TS 16949 standard.

Quality of components

Open Parts starter batteries stand for power and reliability thanks to the high number of plates and the advanced manufacturing technology.
The plates processed with the use of 99.998% pure lead without alloys ensure a higher power level in extreme weather conditions.
The use of expanded metal Ca/Ca technology guarantees cold starts, greater number of charge/discharge cycles, and lower water consumption.

Longer life

In battery cover there is a thermo-welded labyrinth that recovers part of the acid solution that evaporates, directing it back inside the cells in liquid form, reducing its consumption and increasing battery life.

Higher power

Hermetic Extra Power batteries differ from the other batteries in the range because they feature even more plates within the cells, for higher pickup levels and therefore more power delivered to the car.
