When I went down till then there was no water and I just realized that sump pump in corner wouldn’t run without electricity and there was no battery but I assumed that electricity will be back and it will be fine but within half an hour before I left basement water started overflowing from sump pump.

Tesla is building their new semi-truck factory next to their battery factory, Microsoft, Apple and Google are investing millions into data centers.

Does it have battery wall to power at night. 

I once spent all night pumping 3 feet of water out of a basement, in a monsoon, using a DC pump attached to my truck battery because there was no electricity to the house and the sump pump couldn't work.

Also lots of small things filter & smoke detector batteries need changed, hardware is missing from one cabinet.

I just came back from a vacation to GA and heard about a Mega EV and EV battery plant under construction outside of Savannah that's opening up in 2025 that's expected to employ 8100 people.  

You just have to remember to put the battery changes on your annual maintenance schedule.

The reason I ask is that the mining of battery minerals is big there.    

There is also VinFast, WolfSpeed, the Toyota Battery Plant, ... large pharmaceutical companies, manufacturers, energy producers, and a diverse cross section of other industries who are moving to or expanding within an hour of Raleigh.

Good battery life, strong motor, works excellent.
