 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

The normal battery with 1307 RTC's etc, is the 2032 cell, but the CG board uses a much smaller battery. What is the expected lifespan of this smaller battery over the ten years or so expected on the 2032 cell? IT IS NOT A PROBLEM FOR ME - I am just curious as to the difference in lifespan between the two cells. Smoke makes things work. When the smoke gets out, it stops! |

Graeme, what is the battery code used in the CGColorMax1? Plug in the battery code into Wikipedia and you can find out its capacity. You can then compare it to the CR2032. It will give you an idea of the batteries capability relative to the CR2032. The biggest factor in battery life is the time that the CGCM is powered off. I believe that the battery is not used when the machine is powered on. After all of the above you may be able to make a guess about the battery life. Bob |

The current drain is so little that the limitation is the shelf life of this type of battery, which is 10 to 15 years. Geoff Graham - http://geoffg.net |

The CGCOLORMAX1 uses the BR1225 from Panasonic. 48 mAh The CGCOLORMAX2 uses the CR2016 at 90 mAh The CGCOLORMAX2 has a place for a header or for wire connections if you want to remove the battery and hook up a different external battery. Micromites and Maximites! - Beginning Maximite |
