Product catalog summary

Overview: The EverExceed Solar Gel Range VRLA batteries are designed for renewable energy applications, offering reliability and minimal maintenance due to their valve-regulated, gelled electrolyte design. They are particularly suited for frequent deep cycles.

Specifications: These batteries operate between -40°C and +70°C, with an ideal range of +20°C to +35°C. They can be stored for up to 12 months at 25°C, with storage time decreasing as temperature increases. Available in 6 and 12 volts, they feature a lead calcium tin plate alloy and a sulfuric acid thixotropic gel electrolyte.

Benefits: The batteries are maintenance-free with sealed construction, reducing corrosion and extending service life. They have a low self-discharge rate of less than 2% per month and meet IEC 60896-21/22 & IEC 61427 standards.

Innovative Features: Key features include a VRLA deep cycle design, thixotropic gel electrolyte, glass micro-fiber separator, and thick positive plate design, making them spill-proof and leak-proof with low internal pressure and gassing.

Applications: Suitable for photovoltaic/solar systems, cathodic protection, navigation aids, telecommunications, remote monitoring, and power backup.

Charging Instructions: Proper charging is essential. For 12 volts, float charging voltage should be 13.5-13.8 volts, and equalization charge voltage 14.1-14.4 volts at 25°C. For 6 volts, float charging voltage should be 6.75-6.9 volts, and equalization charge voltage 7.05-7.2 volts at 25°C.

Electrical Specifications & Dimensions: Detailed specifications include voltage, capacity, terminal type, internal resistance, weight, and dimensions. For instance, the ES26-12G model has a capacity of 26.0 Ah at 12 volts, with dimensions of 166mm x 175mm x 126mm.

Discharge Capacity and Amps Data: Extensive tables provide discharge capacity and amps data at 25°C for various models, with discharge times from 1 to 100 hours.

Performance Data: The document details cycling ability, showing cycles at different capacity withdrawals (20%, 50%, 80%, 100%) and the constant charging voltage required for optimal performance.

Temperature Impact: Graphs illustrate how ambient temperature affects battery capacity, crucial for understanding performance variations.

Recommendations: Maintain a constant charging voltage to keep the battery fully charged during standby and cyclic operations, considering ambient temperature effects on capacity.

Conclusion: EverExceed's Solar Gel Range VRLA batteries are optimized for high cycling applications, with specific discharge and charging parameters ensuring performance across various conditions.
