I have also used the Vinnic batteries, and they have worked well for me - a good value at that price. If you can't find them, you can still save a few bucks at Radio Shack by finding and purchasing a 6 volt camera/photo battery they carry by the Radio Shack catalog number 23-469. It's a Duracell alkaline photo battery, and it's listed as being equivalent to a PX28AB, A544, and 4LR44 types. The "4LR44" gives a clue about it's insides, because if you then pry off its outer shell, you'll find that it's just a stack of four LR44 cells, three of which will work just fine in the Voyager calc. At $3.79, that's less than a buck a cell, a lot cheaper than buying the cells individually at Radio Shack. Just make sure to buy the alkaline version of this battery, as there is also a lithium equivalent out there that won't work.

Indeed, there is no need to overspend. But even at 2.99 per, that's still only about $0.60/year of go-juice.
