PUNCH

The PUNCH technology makes it possible to produce a current conductor grid with increased frame strength and grid threads of a given thickness and shape by stamping the electrode grid. This significantly reduces the likelihood of operational defects such as short circuits and deformation of the electrodes. The surface of the threads of the electrode array has special roughness and structure, which makes it possible to improve the adhesion of the active mass to the surface of the electrodes and, thereby, significantly increase the efficiency of the battery. The dense assembly of electrode packages of a strictly specified thickness has a significant effect on improving electrical conductivity and increasing starting power. This technological solution increased the battery's resistance to deep discharges and, as a result, had a positive effect on increasing the battery life in difficult operating conditions with frequent discharge-charge cycles, typical for cars with a start-stop system.

MAIN ADVANTAGES OF A BATTERY MADE USING PUNCH TECHNOLOGY:

• increased battery life due to higher strength of current leads, as well as their increased resistance to corrosion.
• high starting power - PUNCH technology allows you to automate the application of a special highly porous active mass to electrodes, as well as ensure stability of the thickness of the electrode packages, which improves electrical conductivity even at subzero temperatures down to -40°C.
• batteries are not subject to overcharging - calcium doping of lead current leads (Ca/Ca technology) ensures the "self-switching" property; when the capacity reaches 95-97%, the battery switches to the "smooth recharging" mode.
• low level of self-discharge - calcium batteries have 3 times less than low-antimony batteries, which guarantees the possibility of long-term storage of the battery in a charged state.
• practically do not require maintenance - the effect of minimal boiling of water in calcium batteries puts them in the low-maintenance category. In practice, with a serviceable vehicle electrical system and subject to proper operation, the working level of electrolyte is maintained in the battery for at least 3 years.
