| | | no i disagree with this answer. the HB is designed to be left on normal charge indefinitely. the batts can get a little warm. if they are hot then something is wrong, but a little warm is nothing to worry about. when fully charged and with no load (...)

| | | | | (...) I was guessing here - most chargers don't check for peak charge, since I didn't know if the Handiboard charger did or didn't... If the charger has a trickle charge of more than C/50 or C/100 then NiCds will be damaged eventually on a long-term (...) (25 years ago, 15-Mar-00, to lugnet.robotics.handyboard)

| | | | | | hi dennis, well, it's just a plain C/10 charge circuit. but i was under the impression that nicad's aren't damaged by that. it's possible i'm wrong :-). any other battery experts out there? fred In your message you said: (...) ly (...) ut (...)

| | | | | | (...) Hi Fred, I don't claim to be an expert on these, but what I have read leads me to believe that this may damage the cells if left on too long. For common NiCds (800mah AA' for instance) C/10 should really be considered a fast charge and not a (...) (25 years ago, 15-Mar-00, to lugnet.robotics.handyboard)

I didn't have any 5watt resistors handy, so I put a pretty (...) (25 years ago, 15-Mar-00, to lugnet.robotics.handyboard)
