VARTA® Promotive EFB is a specifically designed battery for high-performance commercial vehicles with heavy cycling use. Promotive EFB conforms to robust vibration resistance requirements, including end-of-frame installation. Its technological features ensures improved performance and roadworthy reliability. The innovative acid circulator effectively prevents acid stratification which is the common problem with deep cycling applications. Manufactured in Europe to highest quality standards, Promotive EFB will reliably power commercial fleets and dramatically reduce downtimes.
Vibration Resistant The hot melt renders the battery even more vibration resistant, because it saves the connectors from breaking. Additional connector fixations hold connectors and plates securely in place. Vibration resistance is even more enhanced – even on rough road conditions.
Extended cycle life Compared with a conventional battery.
EFB Technology Features Scrim is an additional polyester element between plate and separator. The scrim holds the active material in place inside the plate and avoids the erosion of mass. The result: enhanced deep cycle resistance and superior charge acceptance.
The glued fleece helps that the plates keep their proper position at all times and in every condition.
Acid Circulation The acid circulator avoids acid stratification. It’s a construction element that uses the natural movement of the vehicle to keep the acid inside the battery in constant circulation. The acid density stays at homogenous levels, which enhances charge acceptance and extends the overall battery life.
