- Temperature Range: Operates from -40°C to +70°C, optimal below 45°C.
- Grid Design and Paste Formation optimized for long life and low self-discharge.

Specifications
Detailed specifications for various models include nominal voltage, capacity, dimensions, weight, terminal type, internal resistance, maximum charge current, and short circuit current.

Discharge Data
Includes detailed discharge ampere and watt data at 25°C for different battery models, showing performance across various discharge times and voltages.

Overview
The document provides technical specifications and performance data for the Unilyte Range VRLA batteries, including performance curves for different models under various voltage conditions.

Specifications
Performance data for several battery models (UN 2-500, UN 2-600, UN 2-800, UN 2-1000, UN 2-1500) at different voltages (1.67V, 1.70V, 1.75V, 1.80V, 1.85V, 1.90V) is listed, with capacity measured in Ah across various discharge rates.

Performance Data
Presented in tabular form, showing the capacity of each model at different voltages. For example, at 1.67V, the UN 2-500 model has a capacity of 2038 Ah, while the UN 2-1500 model has a capacity of 6112 Ah.

Key Observations
The data indicates that as voltage decreases, battery capacity increases, consistent across all models, suggesting lower voltage conditions allow for higher capacity utilization.
