Hello,
I want to use my solenoid with a 9 Volt battery but it only accepts a maximum of 5 Volt.
I have tried like a couple of times using it with the 9V battery just to see what happens and it just gets a little bit hot(barely hot to be honest). The thing is that in my arduino project i will give power to the solenoid every 500 milliseconds and for a total of 10 seconds.
Will i damage my solenoid if i use the 9V battery considering that it's only for 10 seconds?
Solenoids use current with a nominal voltage.
What 9v battery , what solenoid ?
Post links.
The answer is to ditch the 9v battery and use 4 AA NiMH.
Using the 9v is like using 6 AAAA batteries when all you need is 4, but there's no reason to use AAAA since AA's will do fine and are accessible.
A 9V battery may not be able to supply enough current to operate the solenoid. Even if it can, the battery won't last long.
I'm using a normal 9V battery like this one (http://coolesttoysonearth.com/media/catalog/product/cache/1/image/600x600/9df78eab33525d08d6e5fb8d27136e95/d/u/duracell-9v-battery-web_1.jpg)
And this solenoid (Solenoid - 5v (small))
I want to use the solenoid with this battery (as i have a lot of them from a previous project) instead of buying AA batteries. With the 9V battery the solenoid respond quite fast so it gets enough energy.
The internal resistance of the battery will limit the current. 9v batteries have limited storage so will go flat very quickly.

ZHO-0420S-05A4.5 means a 5volt 4.5ohm solenoid, so >1.1Amp@5volt and 2Amp@9volt.
But that site could be wrong. It could be 05A45 (5volt/45ohm).
Measure the coil resistance...
In both cases it's not a job for a 9volt smoke alarm battery.

That size of 9V battery is called a PP3 and is not suitable for any power application (not suitable
for motors, relays, servos, solenoids, high power LEDs). It has very little current to speak of (50mA
is about it for most, although the rechargable one's might do a little better).
These small 9V batteries were invented to power portable transistor radios with low current drain. Try
to pull more current and the voltage drops a lot, the cells get hot and the capacity is greatly reduced.
You solenoid appears to be 30 ohm, 1.2W, so at 5V requires 170mA - they will be overloading PP3s
