What Is Battery Autonomy?
Battery autonomy is the period of time a UPS battery will last for at a specified load level in the event of a power outage.
Autonomy can also be referred to as backup, discharge time, or runtime. It is a function of battery charge state, load size, and capacity.
UPS battery autonomy can support loads for just a few minutes through to several hours, although for longer runtime applications, it is more cost-effective to combine a UPS with a backup generator.
Adding extra battery strings connected in parallel will increase autonomy, although it is important to consider the charging capabilities of the UPS.
