High-compression AGM technology for over 99% recombination efficiency.
Proprietary Fixed Orifice Plate Pasting technology for consistent performance.
Nano-carbon enhanced active material for improved cycle performance.
Heavy-duty copper terminals for ease of assembly and safety.
Advanced lead alloy for reduced grid corrosion.
Optional flame-retardant ABS container.
Safety one-way fireproof release venting system.

Standards and Compliances
The batteries comply with NEBS, EUROBAT "Long Life", BS 6290 PART 4, IEC 60896-21/22, Bellcore TR-NWT-000766, and ANSI TI: 330 standards.

Manufacturing and Safety
Advanced manufacturing technologies include automated sealing detection, computer-controlled acid filling, and temperature-controlled formation processes. Classified as non-hazardous for transport by surface, marine, and air.

Construction
Features calcium/tin lead alloy grids, a highly porous glass micro-fibre separator, and reinforced ABS housing for minimal resistance and optimal electrolyte absorption.

Electrical Specifications
Details on nominal voltage, capacity, short circuit current, internal resistance, terminal type, weight, and dimensions for various battery models.

Discharge Data
Comprehensive discharge data for different models, detailing discharge times at various voltages and temperatures.

Procedures
Recommended charging voltage is 2.27 V/cell, adjusted based on ambient temperature. Constant voltage charging is advised, with a float voltage range of 2.25VPC to 2.30VPC at 25°C, and an equalize voltage of 2.35VPC for 12 hours.

Temperature Compensation
Necessary for 0°C to 40°C, with adjustments of 3 mV/°C/cell above or below 25°C.

Recharging Time
Depends on charging current, provided for up to 50%, 70%, and 90% of capacity at 25°C with a charging voltage of 2.27 V/cell.

Self-Discharge
Includes a graph showing self-discharge in relation to storage temperature, indicating capacity retention over time.

Recommendations
Emphasizes constant voltage charging and temperature compensation to ensure optimal performance.

Standard Range VRLA CONSTRUCTION - AGM battery construction is as shown in the diagram below. The positive and negative grids are cast from a advantage low calcium / high tin lead alloy to reduce grid growth and corrosion. The active material is manufactured from best purity lead (99.994%) to minimize the negative effects of impurities. Separator is mat of random woven acid resistant glass fibers, which acts as sponge - soaking up and immobilizing the electrolyte whilst maintaining good acid to plate contact and availability during discharge. “U wrapping” is employed to eliminate the risk of...
