If we're talking one of the classic '9 volts', what is this? $1.00?
And, with one of those Radio Shack 'Battery Club' cards - getting a free
battery per month for a year - then you could be talking *zero* cost
(this is some of what I've done). I know that some of the Adept stuff
uses (for example) those 12 volt (lighter?) batteries - but I still
contend even with a couple of dollars for a single flight use (and I've
seen these 12 volt batteries for, I believe, UNDER $1.00 in quantities
of 10 from Digi-Key). The typical cost of an electric match for
ignition of a typical HP rocket motor will cost you more than that.
If one is talking a $25 rocket, it may be up in the air about this
policy - but for anything more, it's just not worth it (heck, those 9
volts can be 'recycled' for smoke alarms and such).
I know of *several* rocketeers who, when their rocket was 'in trouble',
would pay $50 on the spot to save their rockets. Problem is, there is
no way to transmit that $50 worth of gold plated, Mil Spec, NASA
approved battery up to that rocket when it's 1000 feet up, coming in
fast, and TRYING to eject with a wimped out battery. However, if there
were, they would do it.
Admittedly, it seems excessive on the surface - but one should look at
'power sources' as just as expendable as the propellant in the motor -
one shot and it is over. I mean, even IF the rocket is valued at
nothing, why 'blow' $50 worth of propellant (alone) and have the flight
My policy - one shot and it's over - recycle to some other use -
period. No exceptions. Not ever.
