Any idea what, if any, is the difference between these "ultra pro" batteries and the rayovac "high energy" batteries?

There may be literally no difference between the two, other than the UltraPro, historically, was marketed to business/non-profit/government in larger quantities and at a lower per-battery price, sold in 12-packs, whereas the retail batteries were sold in 4-packs, etc. Now, the lines between the two have blurred.

What voltage are these Rayovac UltraPRO Alkaline C Batteries, ALC-12, 12-Pack

I'm sure Kirk Bolton is correct. They are assuredly 1.5 volts. However, be careful about rechargeable size C batteries they are almost always 1.2 volts. I bought some and found out the 1.2 volts isn't forceful enough to power a Roomba Lighthouse or Virtual Wall- the gadgets that keep the Roombas in their place. The only 1.5 volt rechargeable ones that I have found are VERY expensive.

are these batteries ccan cell batteries

I don't understand the question. Not familiar with ccan.

What is the shelf life / expiration date?

Will vary by seller. Current newest available item has a Feb. of 2028 shelf life date. This is what we sell.
