Volt Polska Gel VPRO Solar batteria 12V 220Ah

The Volt Polska Gel VPRO Solar 12V 220Ah Battery is a high-performance deep-cycle gel battery designed for demanding solar PV systems, UPS, emergency power, and telecommunications applications. With a nominal capacity of 220Ah (C100) and 200Ah (C20), this maintenance-free, sealed VRLA battery delivers reliable power over a long service life of 10-12 years at 20°C. Its advanced gel technology ensures leak-proof operation, low self-discharge (<3% per month), and excellent cycle life (~1200 cycles at 50% DOD).

Advantages

This battery offers exceptional durability and safety. The gel electrolyte eliminates spillage and reduces internal resistance (<3.5 mΩ), enabling efficient charging and discharging. It supports high charging currents up to 66A and operates reliably in temperatures from -20°C to 50°C. The ABS housing provides robust protection, while the valve-regulated design prevents gas buildup.

Suitable for

• Solar photovoltaic (PV) systems
• Uninterruptible power supplies (UPS)
• Emergency backup power
• Telecommunications equipment
• Off-grid and renewable energy storage
