I have noticed that AA alkaline cells are every so slightly longer than the original NiCads and cause compression damage to the contacts and the plastic battery compartment cracks. My thought is NOT to use AA alkaline cells ever but use Nicad or maybe NiMh cells exclusively.

This is correct, you should not ever use regular alkaline cells, the button on top adds to the length and will break the spring contacts (if not on first or second insertion, it will eventually). You should only use a pack made with flat-top NiCD or NiMH cells. Spring foam on the bottom of the pack will keep the pack tight without damaging the contacts. Also, using such cells makes it easy to charge them outside the machine, don't risk frying your ACT by charging them in the Spice.
