A battery backup, or uninterruptible power supply (UPS), is primarily used to provide a backup power source to important desktop computer hardwar e components.In most cases, those pieces of hardware include the main computer housing and the monitor.mportant Battery Backup Facts. In addition to acting as a backup when the power goes out, most battery backup devices also act as power conditioners by ensuring that the electricity flowing to your computer and accessories is free from drops or surges.
In low-voltage conditions the UPS will use more current than normal so it may need a higher current circuit than a normal device. For example to power a 1000 watt device at 120 volts, the UPS will draw 8.32 amps. If a brownout occurs and the voltage drops to 100 volts, the UPS will draw 10 amps to compensate. This also works in reverse, so that in an overvoltage condition, the UPS will need fewer amps of current.
