Back-UPS Pro 1500 - battery blinking, before it needed replacement??

[Anonymous user]

Hello

I've bought this UPS 2years and 2 months ago, devices connected to it (PC and displayes) are turned on 24 hours. Load is 25% or less according to display. There was no problem with UPS win past.

Yesterday I've heard noice and saw battery needs replacement icon on display. I've turned off, removed battery, put it again, tried it several times. I've also pressed power button for more than 5 seconds. 

However the situation now is like this - there is no battery needs replacement icon any more but battery icon is blinking. In Powerchute personal edition I've chosen that I've replaced battery (what is not true - I've put exactly the same battery) and I cannot run manual self-test (button is inactive).

Question - does it mean that battery really needs replacement or maybe there is something else going with UPS? I haven't noticed any other problems, there are no Fxx codes on display, before UPS was making self-test from time to time and everything was always fine (last self-test was passed 27.12.2017).

Is it somehow possible I haven't put battery right? ( I don't hear any click or something like this when I push it).

Hi,

Have you checked the battery voltage? A good 12 volt battery should read around 13.6.
