High Performance Valve-Regulated Lead-Acid Battery OPZV Series
At Felicity, we specialize in energy storage solutions that combine safety, durability, and stable performance. Our line of lead-acid batteries, particularly our OPZV series of valve-regulated lead-acid batteries, is designed to provide stable power for solar installations, backup systems, and hybrid energy applications. Each lead-acid battery is meticulously designed for reliable operation while minimizing maintenance, making it an ideal choice for both residential and commercial environments.
Features and Usage
Felicitysolar’s OPzV series valve-regulated lead-acid batteries utilize stationary GEL cells and tubular plate technology for superior performance and high reliability.
- Designed and manufactured in accordance with DIN standards, these batteries utilize die-casting positive grid and a proprietary active material formulation.
- They offer a float charge design life of over 20 years at 25°C, far exceeding DIN standards and making them suitable for cycling under extreme operating conditions.
- Easy Installation: The lead-acid batteries can be installed in a cabinet or rack and connected to an inverter, charge controller, creating a reliable GEL solar or hybrid system.
Advantages from a User Perspective
From the perspective of managing energy systems, our lead acid battery and valve regulated lead acid battery products offer several key benefits:
Longevity: These lead-acid batteries are designed for deep-cycle use, maintaining stable capacity even through 20 years of daily charge and discharge cycles.
Consistent Output: Stable voltage delivery ensures reliable performance for appliances and equipment.
Flexibility: Perfect for solar energy storage, emergency power, and hybrid energy systems using multiple valve regulated lead acid batteries.
Minimal Maintenance: No regular watering or complex upkeep is required.
The following data from the FL-OPZV 500AH 2V, part of our OPZV series valve-controlled lead-acid battery, provides a more obvious understanding of these advantages:
- Capacity: 500Ah @ 10 hour rate, 1.80V per cell @ 25°C
- Maximum discharge current: 2000A (5 seconds)
- Internal resistance: Approximately 0.65mΩ
- Maximum charge current: 100A
- Terminals: Threaded insert and bolt (F10-M8)
In practice, we deploy lead acid batteries and valve regulated lead acid batteries in homes, small businesses, and telecom systems. Their sealed design and tolerance for temperature fluctuations make them adaptable to different climates and conditions.
