Full Gel Lead
The Haze HZY12-33EV battery represents a professional lead-acid solution with Full Gel technology, designed for industrial applications and electric vehicles that require high performance and constant reliability. Designed to guarantee up to 700 charge cycles , it ensures operational continuity and stable performance even in the most intensive uses. The compact dimensions of 19.6 x 13.1 x 16 cm make installation simple and versatile, perfect for small spaces. The design allows for safe operation in a temperature range of -20°C to +50°C , ensuring stability and operability even in critical environments. Completely Made in Italy , this battery stands out for its quality and reliability, confirming itself as an ideal choice for professionals and operators in the sector.

The Haze HZY12-33EV uses the latest-generation Full Gel technology, with immobilized electrolyte, Amersil microporous separators, and Degussa amorphous silica gelling agent. This construction guarantees complete absence of leaks and a higher level of safety than traditional lead-acid batteries. The flat plates with a kneaded grid and the use of ultra-pure lead allow for reliable performance even during intensive work cycles.

Designed for continuous industrial use, the battery offers a capacity of 28.3 Ah (C5) and 36.4 Ah (C20) , ensuring constant energy supply over time. The internal architecture is optimized to sustain up to 700 charging cycles , ensuring stable voltage and uniform performance throughout its entire operating life.
Measuring 19.6 x 13.1 x 16 cm and weighing 10.4 kg , the HZY12-33EV is easily installed even in limited spaces. Left-hand positive polarity and F-M6 pins ensure quick and secure connections, compatible with most industrial electrical systems, reducing assembly time and simplifying integration.


The battery supports precise charging parameters: float between 2.27 and 2.3 VPC , cyclic charging between 2.35 and 2.4 VPC and maximum voltage of 2.4 VPC , with ripple less than 3.5% . Safety is ensured by an EPDM vent valve and epoxy- sealed terminals, preventing electrolyte leaks and increasing reliability even in the most demanding applications.
Made entirely in Italy , the HZY12-33EV uses a high-strength ABS container and lead-calcium-tin alloy grids. Careful selection of materials and high production standards ensure solidity, chemical stability, and long-lasting performance, making this battery a reliable choice for professional and industrial applications.
