Customers report the following problem:
The online light of the UPS turns off and automatically switches to battery power even when there is no power outage. Similarly, when a cold start is performed, the online LED may blink before the “on battery” light comes on, which means the UPS is using battery power. When a self-test is performed the same thing happens. While the UPS may provide power, the power comes from the battery. Replacing the battery may have no effect since the issue may be with the UPS itself.
Here is our advice, based on APC forums:
The first thing to check is the power outlet where the UPS is connected. It may be a simple issue of the power outlet not working. But, if there are no issues with the power outlet, it will be necessary to check the input circuit breaker of the UPS. If it has been tripped, it should be reset by pushing it until it clicks. But, if the circuit breaker has not tripped, the power cord is the next thing to check. The issue may be caused by a loose or damaged power cable.
It is also recommended to consider the average lifespan of a UPS device, which is from five to seven years. When the device has reached the end of the lifespan, it may be necessary to replace it. There are some manufacturers offering Trade In programs for its customers, which give significant discounts when they trade in their old UPS units. This will allow users to save on the cost of acquiring a new UPS unit. Users can also check out a refurbished UPS, which may be cheaper than a brand new unit.
