You’d probably get a couple of launches from a single A23 before having to bin it, unless it’s a rechargeable one. You could use a few in parallel to improve the current capacity, but why bother!
You would be better off with a small 3S LiPo if you’re after something that will give you close to 12V, but even a 2S or 1S LiPo has significantly more current capacity than an A23.
The A23 batteries were used in many Adept altimeters but had a big capacitor to help it out because of its very high internal resistance. Even though the altimeters were intended for use with low current things like ematches or flash bulbs.
