how do the lights work by battery?

the lights work based on water pressure, so you dont need to worry about setting any electric currents into the shower (that would be a huge negative, dangerous to boot). How the water pressure turns them on I couldnt say, but its the water pressure.

I believe there is probably a little turbine inside the head that is turned by the force of the water, which powers the lights

No, water turns a turbine mechanism inside and it generates its own electric, like a hydro-electric dam

I really don't know. It was a gift for my granddaughter and within a short period of time it quit working. She was disappinted and as I was too.

There are batteries inside the light. You have to remove the paper that stops it from activating though. Mine works but it is always better to have spare in case the batteries inside are dead on arrival!

You don't add a battery, the battery is a small lithium battery internal to the light. The solar panels charge the battery during sunlight periods so you can use the light at night when it is dark. It wouldn't work without the internal battery. You never have to buy batteries for this light.

This is probably provided to allow the batteries to charge initially when the lights are first placed outside. With the off switch, the batteries can fully charge without the lights coming on at night and draining the batteries.

It works without batteries. When you pierce the wire insulation, thats hiw it gets it's power. The alligator clamp opens and you place it on metal for ground. That nakes the connection for a circuut wich activates the light.

The batteries are very easily accessible. The light it self slides easily into the base and is held in place with a simple finger screw. just loosen and pull the whole light assembly out of the base to change the batteries. I love these lights!!

The batteries are in the base. A plate mounts to the wall and the base sides on and off this base easily for battery servicing. I like the lights. They are definitely what I was looking for.

Neither. When the batteries are placed inside, the lights go on. Then after awhile, they will turn off. When you put the light in a dark place, they are supposed to activate, but it fails to do that. It does not turn on in either the day or the night.

The lights came already working, so I assume they were hooked up. They have a solar looking panel on the top, so I assume they are rechargeable, but since I just received them, I am not sure of these answers. Three did not work when they arrived.

Use regular AAA batteries. These are not the greatest quality of lights, I have several that have not worked and several that have stopped working.

If I remember correctly, there are batteries included. Also, there are paper tabs that must be removed in order for the batteries to make necessary contact... I might also add, It will take a few days of sunshine before the lights reach their full brightness!

There is an on/off switch under the "cap". You switch it on and put them in the sun. The battery charges with the sunlight. Then when it gets dark the light glows. You leave the switch on all the time. These are made of plastic but very cute in my garden.

Yes the lights can be battery powered. I am not sure of the time that they will run. I used 8 AA batteries run in series to create the 12V necessary to power the lights as a test. I had the lights running for at least 5 minutes on alternating flash with the 12V battery pack.

Yes, they have rechargeable batteries that are charged by the small solar panels on the top of the light.

Yes, make sure both lights are grounded well on the frame. I wired a toggle switch into the power wire to turn them on and off. Not super bright but they work, no batteries.

The light is using the solar panel as the photo cell. And the battery and switch is inside the light fixture. So the light can used as a working light when unplugged from the solar panel.

They will run fine on those batteries. The lights consume very little power since they are LEDs. The time they will run will depend on the amount of batteries you choose to run in parallel.
