When it comes to power outages, little can be more costly to data centers than unforeseen downtime. According to the Uptime Institute’s most recent report: 54% of data centers reported outage costs over $100,000 USD. 16% of data centers reported outage costs over $1,000,000 USD. In order to avoid costly outages, it’s vital to ensure the health of the backup battery system that is required to perform when power is lost. Be ready for any negative occurrence with 24/7/365 remote battery monitoring and make sure your system is ready to perform as needed when called upon. If not, you run the risk of finding out there is a battery failure after it’s too late and a costly outage is inevitable.
