EPS™ General Series VRLA Battery 

The EPS™ series offers 5 years full maintenance free design life. With optimum design
and good reliability, this series is highly suited for security and alarm systems, UPS systems,
emergency light systems and other small backup applications.

Maintenance & Cautions 

• Ensure all batteries operating in a series based connection are not charged excessively;
• Ensure all batteries operating in a series based connection are not discharged excessively;
• Batteries must be charged with the correct voltage;
• Recharge capacity will be 1.1 - 1.15 times the discharge capacity;
• Effect of temperature on cycle charge voltage: -5mV/degrees per cell;
• It is imperative the battery is always in an upright position and never on its side.
