I have alarm #149 showing on my Dell Rack 1000W UPS. The user manual says this alarm is "A faulted battery string has been detected and as a result, the charger is disabled." Reseating the battery did not resolve the error. I switched the battery with another similar UPS, and no error appeared, so the problem might be in the UPS and not related to the battery. What could have gone wrong if not the battery? Any further tests I can do? Can I simply re-enable the charging?
Appreciate your help...
