Battery power too low to support load

[Anonymous user]

Hi,

My Smart-UPS 3000 RM has recently started logging the following errors every other day or so. It claims the battery power is too low to support the load, then a minute later it claims the battery is fully loaded again. In Quick Status, the capacity of the battery is 100% and the load around 55%.

10/02/2009 19:12:49 UPS: A discharged battery condition no longer exists.
10/02/2009 19:11:46 UPS: The battery power is too low to support the load; if power fails, the UPS will be shut down immediately.

Last battery replacement was in 2005, so the battery is certainly getting close to its end of life. Still, I wonder if this is the problem as it seems strange to me that the battery only takes one minute to load again as indicated in the following log.

Could something else be causing these warnings/errors?

Thanks in advance for your help,
Anita

Anita,

You will receive these messages when the UPS runtime remaining is at or close to the Low Battery Signal duration. Click on the below link which explains the root cause of these messages.

Secondly, typical battery life is three to five years depending on use and environment (temperature). As the batteries age, they lose their ability to hold a charge and therefore available runtime will decrease over time. Since the batteries are four years old in your unit, you may need to replace the batteries in the unit to correct this situation.

I hope that this helps.
