Overview
Kunter Battery specializes in lead-acid battery technology, widely used in China's automotive and industrial sectors. The brand offers both flooded and valve-regulated lead-acid (VRLA) designs, with capacities ranging from small motorcycle batteries to large stationary units for renewable energy systems. Manufactured with advanced plate alloy technology, Kunter batteries demonstrate improved charge acceptance compared to conventional designs. The company holds ISO 9001 certification and supplies original equipment manufacturers (OEMs) in addition to aftermarket distribution channels.
Physical and Chemical Properties
Kunter batteries utilize lead dioxide (PbO₂) positive plates and sponge lead (Pb) negative plates immersed in sulfuric acid electrolyte (H₂SO₄). During discharge, both plates convert to lead sulfate (PbSO₄) while the electrolyte loses density. The AGM (Absorbent Glass Mat) variants immobilize the electrolyte in fiberglass separators, enabling maintenance-free operation and reduced gas emission. Gel-type models use silica-thickened electrolyte for enhanced deep-cycle performance in solar applications. Standard models achieve 300-500 cycles at 80% depth of discharge.
Main Applications
Automotive applications constitute approximately 60% of Kunter's production, particularly for start-stop vehicles in China's domestic market. Their batteries feature enhanced cyclic durability to withstand frequent engine restarts. Industrial applications include uninterrupted power supply (UPS) systems for telecom base stations, where Kunter's 2V/12V series batteries offer 5-8 years service life. Renewable energy storage solutions employ specialized deep-cycle models with thicker plates for photovoltaic systems, particularly in off-grid rural electrification projects.
Safety and Storage
Proper ventilation is mandatory during charging to prevent hydrogen gas accumulation. Kunter's VRLA models incorporate pressure relief valves that reseal at 2-6 psi, reducing electrolyte loss while maintaining safety. Long-term storage requires periodic topping charges every 3-6 months to prevent sulfation. Batteries should be kept at 40-70% state of charge if stored below 0°C to avoid electrolyte freezing. Always disconnect negative terminals first during installation/removal to minimize short-circuit risks.
B2B Procurement Guide
Industrial buyers should specify: 1) Voltage (6V/12V/24V systems), 2) Capacity (Ah at 20-hour rate), 3) Terminal type (Asian/European/American standards), and 4) Case dimensions for compatibility. Bulk purchases (100+ units) typically secure 8-12% discounts, with MOQs varying by model. Lead times average 15-30 days for custom configurations. Third-party testing reports for IEC 60896-21/22 compliance are available upon request. Consider FOB China port pricing versus CIF terms for international shipments.
