They are available all over the place but, unfortunately, come with a wide range of type numbers...have a look at http://www.hpmuseum.org/collect.htm#dispbatt for a bit more information about equivalent types. The lithium types listed will also work but will not last as long as the silver oxide types. Regards, and happy hunting... JasonG

Radio Shack Batteries for Voyager & Pioneer Message #5 Posted by Karl Schneider on 19 Dec 2002, 4:28 a.m., in response to message #4 by Randy Just yesterday, I bought three German-made, sealed silver oxide #76 cells at Radio Shack for a Voyager calc. P/N is 23-009; price was $2.99 each. They didn't seem to have the cheaper alkaline type.

If you can find them the Vinnic brand of batteries is very inexpensive and actually work rather well. A card of 10 cells sells for $2.50-$3.00. They show up on Ebay quite regularly.

Re: Radio Shack Batteries for Voyager & Pioneer Message #7 Posted by OJM on 20 Dec 2002, 8:02 a.m., in response to message #6 by David Smith 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.
