Hi Rick, Thanks for the tips. >1) 150 ma "trickle" is a little high for the 8AA stack (20 hr charge >rate> You're right it should be .05 of 1500ma = 75ma >4) Your input pins on the two regulators need a 0.1uf bypass to the GND >pins of the regulators too. OK, I added them same problem. >5) Don't forget that your voltage divider/sampler draws a small amount of >current from the battery when the charger is unplugged. OK, I am still testing at this point. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
