Backup batteries are used in uninterruptible power supplies (UPS), and provide power to the computers they supply for a variable period after a power failure, usually long enough to at least allow the computer to be shut down gracefully. These batteries are often large valve regulated lead-acid batteries in smaller or portable systems.
Small backup batteries may be primary cells; rechargeable backup batteries are kept charged by the prime power supply. Backup batteries in aircraft keep essential instruments and devices running in the event of an engine power failure.
The following is a list of parameters that may be specified by a manufacturer for a given type of battery. For example, in a typical battery for a general car, the energy density is not relevant - a battery is a small fraction of the total battery weight and consequently this parameter would typically not be listed for a conventional car battery.
The battery keeps all necessary items running for between 30 minutes and 3 hours. Large aircraft may have a ram air turbine to provide additional power during engine failures. Backup batteries are almost always used in burglar alarms. The backup battery prevents the burglar from disabling the alarm by turning off power to the building.
A local backup battery unit is necessary in some telephony and combined telephony/data applications built with use of digital passive optical networks. In such networks there are active units on telephone exchange side and on the user side, but nodes between them are all passive in the meaning of electrical power usage.
Data center UPS backup batteries may be wet cell lead-acid or nickel cadmium batteries, with lithium ion cells available in some ratings. Server-grade disk array controllers often contain onboard disk buffer, and provide an option for a "backup battery unit" (BBU) to maintain the contents of this cache after power loss.
