What is a 12V Server Rack Battery and How Does It Work?
A 12V server rack battery is a specialized rechargeable battery designed to provide backup power to servers and other critical equipment within server racks. These batteries ensure continuous operation during power outages, protecting data integrity and maintaining uptime. Typically, they are available in various chemistries, including lead-acid and lithium-ion, with lithium-ion being the preferred choice for many modern applications due to its efficiency and longevity.
What is a server rack battery?
A server rack battery is specifically designed for use in data centers and IT environments where reliable power supply is crucial. These batteries are often mounted in standard 19-inch racks and can vary in size and capacity depending on the application requirements. They serve as an uninterruptible power supply (UPS), providing backup energy when the main power source fails.Chart: Overview of Server Rack Batteries
