Is it possible to connect several batteries to one UPS?

Question

Uninterruptable power source

Actually, 6 acb 12v9a.ch appeared on the farm. They were written off from the UPS, they will still live, not swollen, without cracks and with the same voltage. The farm has only an ordinary UPS for 700 watts with one battery. Actually, there are three questions
1. Is it possible to simultaneously charge 6 batteries with one UPS at once, is balancing necessary (I’m ready to sacrifice charge time)
2. Is it possible to power a load of 600 watts with such a Frankenstein? do not want to sit without a split system)
3. In general, the idea of ​​\u200b\u200bnorms or score and buy a normal UPS?

Answer 1

1. In parallel, it is possible and necessary to extend the operating time. There is no need to balance when connected in parallel. By itself, the charge time will increase significantly.
2. Depends on the UPS, if it can carry the load, it is possible that after 15 minutes it will start to overheat, and after half an hour it will melt. If the heating is slightly above normal, then you can try to attach a fan by cutting a window into the UPS and connecting the fan to a relay that switches the load to the battery so that the fan turns on automatically.
It should be understood that for a UPS, the power can be indicated not in watts, but in VA, in watts this is about 20 percent less.
It is also worth understanding that electric motors work extremely badly from a UPS and most likely a split system will not work from a cheap UPS.
3. Try it, if the UPS pulls, then consider yourself lucky.
