Will AA batteries power this solenoid OK?

Hello,

I am building a project that uses a wireless RF remote control to momentarily fire a solenoid to release a latch mechanism.

The solenoid I am using is this one:

It has a 26.7 ohm coil and rusn at 12 volts, so using ohms lay I figured that it will draw about .45 amps during the moment where the plunger is retracted.

Because this project is portable, I would like to keep the weight down. My plan was to go with (8) AA batteries to produce the 12 volt source. So, are eight AA batteries capable of handling a .45 amp current draw for a moment? The solenoid would be actuated for less than a second, and fairly infrequently.

Thanks,

Scott

Easily. Alkaline AAs have a short-circuit current close to 10 amps.

Fresh AA alkaline batteries will easily be up to your task at hand. To get an idea of what they are capable of fresh AA alkaline batteries can typically juice out a fair amount more than 10 Amps (IIRC) of short circuit current into a low resistance short. A typical two cell AA flashlight lamp for instance will often draw around 0.5A from the cells. Zinc chloride and carbon zinc batteries are rather another matter. When these types of batteries start getting even the slightest bit low they have hideously wimpy output capability. Even when fresh and new they are wimpy though could still handle your 0.45A for a little while.

Cool. Thanks for the replies everyone.

Yes, remember to always use alkaline over cheap heavy duty brands. They are far superior in every way.
