      From: ohland@charter.net              Rick, the simplest [and slowest!] rate is c/1, a lot SIMMpler control       circuit and it makes the least heat. I've seen c/5 mentioned, much       shorter time, but more heat and it slaps the battery pack like the       naughty boy it is.              So... if you got to SEE the battery charging circuit, could you       guesstimate capacity?              The pittances we have of 26v and 40mA could mean whatever you wandt.       Measuring the output connector in the battery well -MIGHT- tell us the       actual charging voltage, which could be less than 26v. Maybe the charger       input is 26v at 40mA?              Rick Ekblaw wrote:       > Louis Ohland wrote:       >> Rick, what would be the minimum rated Watt-Hour for the battery pack?       >> 180W over 10 seconds?       >>       >> Assuming a 12v battery pack...       >       > So after all of that thinking and postulating, I went back and looked at       > the Announcement Letter and found:       >       > Battery, Nicad (Internal)        6669 57F0842       >       > so it's a NiCD pack after all.
