Problems in Pakistan are always unique : ), coming back to serious point.
The solution you told me can be done but i can't just keep switching things from here to there all day 3 times. I am not home most of the time and my family can't do that.
Yes the 600w locally made UPS charges very fast, even if electricity goes 3 times for 2 hours it seems to give same backup everytime. My APC 1000w is not supporting the big wet battery, starts beeping when connected to it. Should i put thick wires in the PCB for battery? maybe the thin wires are not supporting the 145AH battery?[ Parent ]
You might be able to do something like that with relays.
AGS is a battery manufacture, they specialize in SLA type used in UPS. Should work if connected correctly to APC UPS. I connected a flooded Lead Acid battery and it worked.
If not then more information will be necessary to figure out why. Battery voltage when connected, How doe the newer ones work with it ect. Many more.
Have fun, Scott. [ Parent ]
