Even if never taken out of the original package, disposable (or "primary") batteries can lose 8 to 20 percent of their original charge every year at a temperature of about 20°–30°C. This is known as the "self discharge" rate and is due to non-current-producing "side" chemical reactions, which occur within the cell even if no load is applied to it. The rate of the side reactions is reduced if the batteries are stored at low temperature, although some batteries can be damaged by freezing. High or low temperatures may reduce battery performance. This will affect the initial voltage of the battery.

So if your battery is older than 1 or 2 years, though it shows you full voltage it might not be capable to sustain enough power. If you have a battery metre you can check this. At home, you can connect a 12V bulb and see how long the battery can provide power without dimming the bulb.

1. 2 years

2. With Multimeter

3.yes

4. still no

5. Beeps then Red LED and Yellow LED Light Then Turn off. I can hear Relays' Sound that is "Tick". When I connect UPS to AC current Same thing happens and Relays sound Than before.

No not troubling to me at all. Just wanted you to check the battery. In my experience with UPSs for about 15 years, mostly if it beeps and LED indicators are working at the times of switch on, it's the batteries. I also had few times that I believed the batteries are okay. But after placing the batteries, the units started to work.

Batteries are like that. When it comes to final stages, you will notice it is not working instantly. But it was degrading for a long time.

So, connect a 12V bulb to your battery and see how long it can retain power without dimming the bulb. Tell me this, so we can move on to next stage of diagnosing.

Magneto is back from a long vacation and he will join with us from here.   :mrgreen:
