hello, is anyone can tell me what is the cause of battery charging indicator blinking although when it reach 100% charging.. i just recently replace the battery.. the model is surt8000xli
The blinking battery charge is an indication that the battery runtime is low. This could be from having a high load on the UPS or the batteries not having enough juice. Seeing you just replaced the batteries that would not be the case. Sometimes you need to run a self-test in order for these units to recognize the new batteries. I would try to run a self-test to see if that clears the flashing LEDs.
