I'm busy resurrecting a Toshiba T100SE. Unfortunately I've found the Ni-Cads to all be dead, The main battery pack is a 7.2v 1700mHA pack (6x1.2v) and then there's a RTC backup battery which is made up of Ni-Cad coin cells (2.4v, 4x1.2v but made up of 4 cells). Anyway I can fudge it with a couple of AA Ni-Cads I have. This is just to make sure it starts up the Intelligent power supply is very picky about the batteries. I currently have a kludge battery pack of AA Ni-Cads (with twice the mAH - hehe) and I'll build a temporary RTC battery out of 2 AA Ni-Cads. So my questions are: - Does anyone have any recommendations for building (or rebuilding) the battery pack? - Any recommendations on the coin cell part? -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies
Could you use a super capacitor instead of the NiCds for the clock battery? On Thu, Apr 26, 2018 at 3:18 PM, Neil Cherry via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

I don't think so, the recharge circuit pushes higher voltages (3.1v) when charging. The intelligent power supply is a little too intelligent for it's own good. ;-) It very particular about what it wants in the line and errors at the slightest fault. But I am curious, do super caps come in coin size? The space in the case is built for a shrink wrapped 1x2 coin setup. Not sure of the equivalent coin size yet. -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies
