AI Thread Summary
A 3Kva UPS with six 12V 17Av batteries provides a maximum backup of 10 minutes under full load. To increase backup time, adding an additional battery bank with higher amp-hour (Av) batteries is feasible if the UPS documentation allows for longer operation. However, using standard car batteries is not recommended for UPS applications; deep cycle batteries are preferred. Mixing different types of batteries can lead to performance issues and is generally discouraged. Ensuring compatibility and using the right battery type is crucial for optimal UPS performance.

I have 3Kva UPS in which it has 6 12V 17Av batteries in it. which give me 10 minutes maximum backup on full load.
What if i would like to increase the backup time,
Can i additionally install car 12V 125Av battery with it?
or additional battery bank with high Av batteries.

Please can anyone guide me whether its feaisable or not.

Thanks

This depends on if the UPS 3Kva rating is continuous or limited to the 10 minutes.

If the UPS documentation says it can run longer, then adding an additional battery bank of high Av batteries is certainly possible.

Plain car batteries are not a good choice for UPS service, you need deep cycle batteries.
Mixing battery types is not a good idea.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
