When it comes to an uninterruptible power supply (UPS), the battery is one of the most important subsystems but can be one of the hardest to understand. In this eBook, we have provided a breakdown of the role batteries play in a UPS.

Along with a refresher on the fundamentals of a UPS, we’ll be looking at battery management, battery configuration and charging, as well as installation, environmental and safety considerations.

This eBook is for you, the hands-on, technically-oriented people in a business. To ensure we have a shared understanding of the terminology being used, we’ve included a glossary at the end.

Providing clean, quality uninterrupted power means having properly installed, monitored and managed batteries. A UPS is the heart of a data center’s backup power, and a single battery cell within a UPS battery string can create a risk of downtime for data center operations.

Regular maintenance of your batteries is critical to make sure you have backup power when you need it, and avoid the costs and other negative implications of a battery-related outage.
