My battery is 12V 7A.Neo wrote:Have you placed the components intact after replacing the battery. I remember you were experimenting with a comparator IC?
What are the ratings of the battery that you have replaced? (is it a 12V, 7Ahrs?)
What happens if you power on the UPS now? Any beeps, indicators?
I have placed everything correct. After replacing LM339 Self turning off problem that i told you earlier corrected not the one i told you yesterday.
I have replaced the LM324 IC then UPS started to work. After that I charged UPS for 8 hours I think Now The error came again. That is
without connecting the AC line UPS beeps for 1 minute then Turns off by it self Doing Long Beep and Lighting the yellow LED. After connecting the Monitor and Computer when power gone UPS turn off by it self Doing a Long Beep.
