Where do you buy your batteries for a good price?

Where is a good place online or otherwise to buy watch style batteries for the calculators in my collection? Also, I have about 8 Summit Calculators, and some of them I really need to crack open and get out the rechargeable batteries. What's the trick to this and what can I replace the battery with? Is it bad to run them off the AC Adapter with the rechargable batteries dead? Thanks in advance!
