EFB technology(Enhanced Flooded Battery)
The EFB (Enhanced Flooded Battery) technology utilizes thicker plates, compared to a conventional battery, stacked in a microfiber film. The plates always keep more active components on the surface due to their wet nature. This technology allows for an increased number of charge-discharge cycles and resistance to deep discharges.
The enhanced charge capacity enables quicker compensation of discharges while the vehicle is in motion. An EFB battery is perfectly suitable for a car equipped with the "START-STOP" system, but it can also be used for vehicles with high energy consumption.
"Megatex" manufactures automotive and commercial EFB batteries under the brand name "A-mega".
Hybrid technology Ca+ with a cast grid
• Unique vibration resistance on any road surface.• 100% maintenance-free - low water consumption thanks to a unique paste formula.• High resistance to deep discharges (high-tech alloys containing divalent metals).• Long service life.• Low self-discharge.• Use of high-quality electrolyte.
The unique paste formula used in the production of commercial batteries enables high cranking performance, stability of characteristics throughout the entire service life, and high durability.
Ca/Ca technology witha perforated grid
• High corrosion resistance.• Serviceability.• High cranking current.• Low self-discharge.• Low water consumption.
This technology is used for the production of automotive batteries models M3 and M2.
Ca/Ca technology with a cast grid, also known as Gravity Calcium Cast inside.
• 100% maintenance-free - low water consumption.• Low self-discharge.• High cranking currents.• Long service life.
The technology is patented by "Megatex" LLC.It is used for the production of automotive batteries models M5 and M7.
