| UPS battery autonomy time
UPS batteries are used to generate back-up energy by UPS during power outages. Here the battery must be capable of supplying UPS in order to provide the minimum time required for the generator to start or the shutdown time for sensitive devices. |
| Most UPS makers use different types of batteries to provide the power required for longer loads in different ways. For example, a 10KVA UPS may normally charge for 10 minutes and can be increased to 30 minutes by adding the appropriate battery cabinet. |

It is clear that the added battery cabinets will take up more space and require periodic service and maintenance, and the batteries will need to be replaced at the end of their useful lives. |
