Uninterruptable Power Supplies (UPS) provide vital backup power supply for mission critical applications and ensure the continuity of system and data center operation. When a UPS operates during a power outage, the batteries provide DC power that maintains inverter operations to support critical loads. Studies have shown that data loss from power issues is often greater than from virus attacks. IDC Research found that 33% of all server failures are due to power problems. As the importance of a reliable UPS solution for critical loads grows, it becomes increasingly crucial to safeguard against battery failure.
After a UPS is in operation, the UPS battery is the heart of the UPS in terms of availability and reliability. According to some studies, around 60% of datacenter operation downtime is caused by battery failure. Hence the continuity of battery operation is essential to UPS service availability. To ensure operation continuity, Delta UPSs are equipped with intelligent battery management to safeguard the battery and prolong UPS lifespan.
The following points demonstrate the importance of battery management:
Overcharge and deep discharge protection
Overcharging the battery can result in the battery drying out, while deep discharge may shorten your battery life. Users can set the auto discharging time to prolong battery life
Battery Temperature Compensation
The temperature compensation function can monitor battery temperature continuously and maintain an optimal temperature to extend the UPS battery life and achieve maximum performance.
Continuous Battery Monitoring
The auto or manual battery tests can be performed to detect any performance issues or problems in advance. The UPS LCD/LED panel shows the battery’s condition and its capacity in percentage format. The UPS alarm beeps to signal a remaining battery capacity warning while the UPS is in battery mode.
Remote Management
The UPS can connect to a LAN network with an SNMP card or UPSentry 2012 and InsightPower Manager Software to access and display vital information such as battery status, battery measurement, battery cabinet and replacement date on remote workstations. The easy management functionality can prevent premature battery failure, and enhance its service life and reduce battery investment.
Precautions for Battery Installation and Maintenance
In addition to using the Intelligent Battery Management system to detect malfunctions, users should take the following precautions for battery installation and regular maintenance:
- Only use the same type of batteries from the same supplier. Never use old, new, and different Ah batteries at the same time.
- The number of batteries must meet the UPS requirement.
- Do not connect the batteries in reverse.
- Keep the batteries away from fire. A battery may explode.
- The battery can present the risks of electrical shock and short circuiting the current.
- When a UPS is running for the first time, charge the UPS for at least 6-8 hours to ensure the batteries are fully charged before operation.
- Check the battery pack condition upon receiving it from the supplier to avoid any damage from expansion, collision, or leakage.
- Store the batteries in a cool and dry location.
- Avoid installing the batteries near the server room heat spot.
- Fasten the screws when connecting the batteries.
- The best temperature for battery operation is between 19°C to 22°C.
- Conduct regular maintenance.
Without a good maintenance plan or management system, batteries may fail much earlier than you expect. Delta’s innovative Intelligent Battery Management system detects battery failures in advance to protect the continuous operation of critical applications. Maximize the reliability and optimal performance of your UPS and minimize your UPS battery investment.
