1/3AA Lithium battery
Hi,
I am having difficulty finding a 1/3AA Lithium battery. It is for this application, any substitute has to fit in pretty much the same space as 1/3AA, there is no spare room. http://wolzow.mindworks.ee/analog/jx-10-m-16c.htm I did find rechargeable NiMH types, but I don't think they will keep their charge for the years expected of a memory backup battery? Perhaps I could utilise watch type button cells, if I could find a holder for them. Cheers, Gareth. |

Peter Wieck Melrose Park, PA I know they are not LiPo batteries, but if they are to be rechargeable, that should not matter. I am hunting another source for an actual LiPo device. |

1/3AA Lithium battery

It is for this application, any substitute has to fit in pretty much the same space as 1/3AA, there is no spare room. http://wolzow.mindworks.ee/analog/jx-10-m-16c.htm It looks to me like this battery is used only for keeping the SRAM data alive. If so, the current draw will be very low. If you can find a smaller 3V cell, that will still work for a long time. You could also stack two LR44 cells. The size should be about right. I did find rechargeable NiMH types, but I don't think they will keep their charge for the years expected of a memory backup battery? Rechargeables are not the right tool for this job. Perhaps I could utilise watch type button cells, if I could find a holder for them. That is a good idea. If you can find a combination of holder and battery that will fit, that would be a good solution. You could look for both dual 1.5V or single 3V solution. Looking at the device, it does not look complicated at all. Are the high prices because of the collectible value, or would people be willing to pay similar money for a new, compatible device? -- RoRo |
