   Bringing you up on charges!

   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?
