what uses 9 volt batteries?

Can anyone think of any kind of device like a flash light a toy that take those rectangled 9 volt batteries. I need to test to see how long it will last and it haves to have those 9 volt connectors too.

 

A fire alarm (the type you stick on your ceiling)

 

get a voltmeter and test it first, then get a snap on thingie with two wires coming out, then get the end off a flashlight that uses round batteries and attach the wires and keep track of the time the light stays on from 9 volts to 1 volt or whenever it goes to dim and test it again.

 

The only things I know of are effects pedals for electric guitars and basses, and my VOM (volt-ohm meter) also uses a 9 volt to test circuit continuity (aka an ohm test).

 

Just take the bulb out of any flashlight. Preferably a MAG-Lite 5-cell. You can just touch the contacts to light the bulb.

 

One of my ten remote controls uses a 9 volt. Also, my remote for my garage door uses a 9 volt. And you could put the battery in your mouth all day and get a charge, lol. That is how I always tested them to see if they were any good, just touch them to your tounge. :<))

 

are you like a retard or something?

 

Is who retarded?

 

well apparently you .....but since you need that little extra help to figure it out ...it was for the thread creator

 

what voltage does a dildoe take ? any ladies like to fill me in .

 

Vibrators take cylindrical batteries. AA or C are common.

The OP needs 6 flashlight bulbs and lenghts of thin wire.

Each flashlight bulb takes 1.5V, so if all six are wired in series that makes 9V.

The wattage of each bulb is noted and totaled.

Wire the battery into the circuit and time how long it takes the battery to run out.

Watts = Volts X Amps.
We know that Volts = 9.
Watts is the total from the flashlight bulbs.
So the battery was putting out Amps = Watts / 9 until it ran dry.

How many HOURS (make sure its in hours not minutes) did it take the battery to run dry.
Amps (from the equation above) X hours = Amp Hours,
which is the "amount of electricity" that a battery holds.

Is that what this is about?

 

if you want to know if it has a charge .....touch it to your tongue

 

Walkie talkies

Some alarm clocks as a power back up supply
Smoke alarms

 

chockin on me spliff

 

Some stun guns and taser guns use 9v. The ol' M26 uses 8 AA.

 

Mrs Bush Vibrator uses those small batteries " George is not very big".

 

I bet the Sybian takes 9 volts.

 

Some electric weighers use them.
