If you’ve ever had a power outage, you know how important it is to have a battery backup system in place. Battery backups, also known as uninterruptible power supplies (UPS), are designed to provide a temporary power source when the main power supply is lost or interrupted. But how long do these battery backups actually last? In this article, we’ll answer some common questions about battery backup systems.<\/p>\n\n\n\n
The length of time a backup battery lasts depends on the capacity of the battery and the amount of power being drawn from it. For example, a 12V 7Ah battery can power a device that draws 1 amp for approximately 7 hours. However, if the device draws 2 amps, the battery will only last for around 3.5 hours.<\/p>\n\n\n\n
A 1500VA UPS (which stands for volt-ampere) is a mid-range backup battery system that can power<\/a> multiple devices. The length of time it will last depends on the number of devices connected and the amount of power being drawn. On average, a 1500VA UPS can power a computer, monitor, and other peripherals for around 20-30 minutes.<\/p>\n\n\n\nHow long does a UPS last without power?<\/h2>\n\n\n\n
