Lithium Battery Replacement Help
« on: April 19, 2005, 03:09:23 AM »
Hi -

I want to replace the old batteries in my A4000 and A2000s before they rot away and destroy my motherboards.  I've ordered the actual holders.  Is there anything special I have to solder in-place as well (diodes / resistors)?  I've seen some pics on the site here that show some electronics wired in-line with the holders.

Thanks for any help ! Or web links of course.

The instructions on Aminet specify a radio shack diode and a 3 volt battery (not a 3.6 volt battery).  Also, Radio Shack does not carry the battery clips anymore.  I ripped some off old PC motherboards.

What is the deal from the previous posting suggesting a different diode?  It hinted it was "at the edge" of the RTC chip.  Does that mean it is at risk of melting it down?

Hi -

Thanks for all the tips and suggestions.  The A4000 project is coming along nicely.  I also purchased a plug converter gizmo that converts a regular ATX supply to work nicely in an A4000 as well.  It is going to be a rainy weekend here in the North Eastern US . . .perfect to work on the old computer !
