Confuses silver oxide with alkaline cells. I just replaced the battery in my garage door opener remote, so retrieved it from the recycle bin. It's a Radio Shack, and says Alkaline on the side of the case. And sure enough, it has a bunch of smaller button batteries inside. So, are these alkaline button cells? Or is the case marking purposely misleading? Wish these were A76 compatible, my HP27S has a healthy appetite for them seeing as I never remember to turn it off myself. Jon |

Wish these were A76 compatible, my HP27S has a healthy appetite for them seeing as I never remember to turn it off myself. Is this the same series as the 28S? A guy at work gave me his when he got tired of buying the special batteries (3) that it uses. He told me they were 3, 3 V cells. I determined that wasn't right, the calculator works fine on roughly 5V. I bought a 4-cell Ni-Cad pack from Digi-Key (4.8 V) and recharge it a couple times a year. But, if I forget to charge it, it runs the cells down to zero and ruins them. So, now I added a switch to turn off the battery when I'm not using it. It erases all memory in the calculator when I do that, but I don't save any programs in the thing, and actually have only programmed it once, just to see how. If I want programs, I have real computers for that. Jon |

Not familiar with the 28S, but a quick search reveals the 28S is RPN where mine is not. I have considered making a special base for this that would take larger rechargeable batteries, but I have way too many projects now. I do have a number of programs in mine. Often when changing batteries I'll lose all the programs. But this is hit or miss. I've gotten old ones out and new ones installed in just a few seconds, and lost everything. I've fumbled the three A76s, taking some 10-15 seconds, and the programs are still there! Jon |

And a minimum of 2 strips (conductors) up the sides (connect 2 stacks for 6v). The ascii art is too painful, I'm sure you'll get the idea without it. Bob |

I've got a RadioShack 6V lantern battery here in front of me, and the size of the case (not counting the springs coming out the top) is only 96 mm high. It's not quite high enough to fit 2 AAs lengthwise so this one can't hold the 32 AAs. Or, in imperial units, the the AAs are 2" long the 6V case is 3 3/4" tall. It's also got the metal sides with cardboard bottom and top instead of the plastic style case shown in the video. The 6v weights 896 g and a 32 AAs weight about 768 g so it looks to me like the idea of making a 6V out 32 AAs would work and could very likely be something some manufacture is doing to reduce costs considering the fact that the AA is the worlds most popular cell size and is manufactured in the highest volumes. The price however isn't all that great. We buy AAs from costco and I think we pay something like $10 for 24, which would be $13.33 for 32. If you could get 32 for $5 it would a nice deal, but if you can't know for sure the 6V you are buying is the type with the AA cells then you loose everything. And if the AA cells inside the case are not the same type or quality as the stand alone cells (like for example they don't have as strong of a case so they are more likely to leak if you use them stand alone), then the deals starts to look questionable. It would be interesting to know if the video is a complete fake, or if it's real, but only a very limited number of the 6Vs are made that way. -- Curt Welch http://CurtWelch.Com/ http://NewsReader.Com/ |

If the current ones are made like that, then the cells would just fall out. That one would fall into four individual cells. Unless they have stopped making the type-F cells for other purposes, I don't see any reason to make it up with a series-parallel array of AA cells.

Different makes and models have different internal construction. I have taken apart more than a few batteries. Some 9-volts had the 6 AAA (or smaller?) sized batteries, some were a stack of 6 rectangles. After all, think about the voltage and proportions of a 9-volt. Some 9-volt batteries consist of 6 AAAA (yes, quadruple A, http://www.google.com/search?q=AAAA+alkaline) cells inside. I know this because when laser pointers were new and cool in the early 1990s I had a very thin pen-styled one that took AAAA's, which were very hard to find, and had to resort to dismantling 9-volt batteries to get them. They used spot-welded tabs to connect, but so small that you could pull them off. Sometimes I would open a 9-volt battery and find that it was a stack of 6 little sardine-can-shaped cells instead of AAAA cylinders. I forget nbow which brands were one type versus the other. I still have that laser pointer. Even though they're cheap nowadays I've never seen one that thin. |

I suspect that portable radios in the past (tube days) used F cells more commonly than today, which is why the 6V lantern battery was designed to be just the right size to hold four F cells.

Guess you don't have a 8,9,12,14,18,24volt electric drill ?
Those are button cells. More buttons the better. Many series to make voltage. Many of those in parallel to make current. Loose a cell and a branch is gone. That is a drop in current. Reliability went up when the buttons were used from larger high current cells. Who knows what the date code on the two batteries. One could be years old and the other not.

Next time I have a dead lantern battery (there's one around here somewhere) I'll open it up and see what's inside. Well ... the video won't play on my system, so I can't see what it looks like, however: 32 cells connected in series would be around 48 Volts (assuming 1.5 V/cell). For six volts, you would only need four cells in series, which suggests eight series sets connected in parallel. Now -- I have opened up 6V lantern batteries in the past to get size F cells for some really old equipment. In some, the cells were strapped together, but in others, the cells were connected by strips of metal mounted in cardboard, with connections made purely by the pressure of the assembly. If the current ones are made like that, then the cells would just fall out. That one would fall into four individual cells. Unless they have stopped making the type-F cells for other purposes, I don't see any reason to make it up with a series-parallel array of AA cells. But it has been at least fifteen years since I last disassembled a 6V lantern battery. Enjoy, DoN. A series, parallel connected cells would prematurely discharge into one another untill they all went dead. It is never a good idea to leave cells connected in parallel for any extended length of time without being used.

Certainly a problem -- though less so with an identical batch of unused cells right from the factory. And assembled into the lantern battery housing, they should be pretty much all at the same temperature, which would minimize the problem as well. Now -- if you added a diode in series with each series string before paralleling them, you should be fine -- but how much would the eight diodes add to the cost of the battery? :-) Enjoy, DoN. -- Email: | Voice (all times): (703) 938-4564 (too) near Washington D.C. | http://www.d-and-d.com/dnichols/DoN.html --- Black Holes are where God is dividing by zero --- |

Obviously a hoax. One contiunous battery would be 48 volts. It is possible that SOME lantern batteries may be made that way, and that the top and bottom holders may have the required circuitry, only requiring roughly half to be installed "backwards" from the rest. You would have 4 sets of 8 cells each in parrallel, connected in series. Roughly 7 amp hour capacity. -- Posted via a free Usenet account from http://www.teranews.com |

However, in practice, it IS done with reasonable results using matched cells from the same batch. Particularly common with lithium cells in computer batteries, and with NimH cells in tool batteries (which DO have a rather poor reliability record) -- Posted via a free Usenet account from http://www.teranews.com |

The "F" designation was for "F"ilament use. Lots of old batteries had 1.5 volt filaments in the rectifier tubes, so you had an "A", a "B" and an "F" battery. Anyway -- I've used 6V lantern batteries as sources for the size 'F' cells for this in the past, and I hope that most vendors still make the lantern battery from 'F' cells. -- Posted via a free Usenet account from http://www.teranews.com |
