I have general lights but apparently, the emergency lights need to be connected to some sort of battery(I’m not an electrician) and piping in order for the lights to stay on in case of a power outage.

HI IS THERE SUCH A THING AS A WIRELESS BATTERY OPERATED HALWWAY LIIGHT WITH A MOTION SENSOR, THAT IS BRIGHT ENOUGH TO BE ABLE TO SEE AT NIGHT ON STAIRCASE?   

Don’t go with battery operated Security Cameras for your smart home setup.

You need to know what exactly is there and if it has value (the contract, the person's electric bills past two years, and an inspection of the batteries/panels/and roof).

DeWalt's 18V XRP batteries are NiCads and, as such, exhibit all the usual NiCad issues such as "memory" and self-discharge.

I've also welded a broken top link on a bush hog with 3 car batteries and jumper cables in the field.

They may also require batteries to start or manual lighting.

It's really not rocket science to screw in a battery-powered trail camera in a steel case next to the front door and another one next to the back door.

Great flashlights and extra batteries that fit, super long extender ladder, korkers/or other brands over shoe to go over your steel toe boots, GFCI tester, moisture meter, a dog nose, an extender mirror, shovel to check foundation moisture, respirator as some properties have gross smells or chemical exposure, regular retractable tape measure forget the laser one, 5 gallon bucket, zip lock baggies, brown paper bags, putty knife, variety of screw drivers,Are you checking basements?

In all the leases I am clear the batteries are the tenant's responsibility and make sure to tell them if it blinks red it's time to replace the battery.
