(...) quite a (...) compared (...) I regularely run my RCXs on NiMH Sanyo rechargable batteries and they works very well. Voltage is lower, but they're much more current capable then the alkaline technology ones. Ciao Mario (24 years ago, 4-Sep-00, to lugnet.robotics)

(...) The only issue with the standard rechargeable ones is if the motor(s) short the resulting current drain could damage something. I'm sure we've all shorted a rechargeable and had the rubber wire casings melt off from the 'heated exchange'.. (...) (24 years ago, 5-Sep-00, to lugnet.robotics)

The motor driver circuits in the RCX are current limited to somewhere around 500 mA if I remember correctly. The driver chips also have a temperature cutoff, so they will not overheat. You can short the motor with no damage. - pete. (...) (...) (24 years ago, 5-Sep-00, to lugnet.robotics)

(...) Perhaps because rechargeables have a faster initial voltage drop than other types and they feel that could make it seem like the RCX has poor performance or isn't working right. Perhaps. (24 years ago, 6-Sep-00, to lugnet.robotics)

(...) If that is the case with rechargeable batteries, then I stand corrected. I do wonder why LEGO would caution the use of rechargeables if they are safe though... Dean -- Coin-Op's For Sale!: (URL) Lego Workshop: (URL) Lego Club: (URL) (24 years ago, 6-Sep-00, to lugnet.robotics)
