Ritar HR Series Lead-Acid Batteries
High-Rate Discharge Batteries for UPS & Critical Power Applications
The Ritar HR Series is a high-rate discharge valve-regulated lead-acid battery range engineered for applications where reliable backup power and high-current discharge performance are essential.
Designed with reinforced grids and specially formulated active materials, HR Series batteries provide stable performance during demanding discharge conditions. The series is particularly suitable for UPS and EPS systems, data centers, emergency power systems, telecommunications infrastructure and other critical power applications.
For high-load applications, the HR Series provides higher power output than conventional battery ranges while maintaining reliable standby performance.
Key Features
High-Rate Discharge Performance
Optimized for applications requiring high current during short-duration backup events, making the HR Series particularly suitable for UPS systems and critical power infrastructure.
Extended Design Life
The HR Series offers a design life of approximately 8–15 years at 25°C, depending on the model and operating conditions.
High Power Density
The battery construction is optimized to deliver increased power output in high-rate discharge applications, supporting demanding UPS loads and reducing the space required for battery installations.
Advanced AGM Technology
A high-pressure AGM separator design helps reduce internal resistance and provides controlled assembly pressure, contributing to stable performance and improved battery durability.
Wide Operating Temperature
The HR Series is designed for operation from approximately -20°C to 60°C, allowing it to perform reliably across a wide range of environmental conditions.
Durable Battery Construction
The battery case is manufactured using impact-resistant ABS material, with optional flame-retardant construction available for applications requiring enhanced fire-safety characteristics.
