Hi Danny,

Beware - this is a serious warning, as the RCX deals with motor
output, rechargeables can behave differently current wise from
non-rechargeables, and this may increase the likelyhood of burn outs
or damaged components when motors are stalled.

Have you seen real failures using some rechargeables batteries? I believe that
the RCX motor driver IC is really foolproof, and I don't think anything could be
destroyed using various kind of batteries (provided that the 9 or 10 Volts
voltage is not exceeded of course...)

(...) I have not seen them on the RCX, but I have on other devices, where power transisotrs have died. Its all to do (I think) with the characteristics under load, and the fact that larger spikes in current may occur with rechargeables. If the IC (...) (18 years ago, 21-Jul-06, to lugnet.robotics)

(...) Depending on the kind of rechargeables you are using, they generally have significantly different characteristics. They also often output a slightly lower voltage (about 1.2 or 1.3v per cell as opposed to the expected 1.5). If you have a (...) (18 years ago, 20-Jul-06, to lugnet.robotics)
