Thanks for asking this question. I've been meaning to do so myself. One of the books shows a modified RCX using a 9.6v RC battery pack. Another (or possibly the same one) talks about someone who increased the voltage of rechargables by using 5 AA, 1 (...) (23 years ago, 13-Jul-02, to lugnet.robotics)

| | RE: Rechargeable batteries and the RCX -- Firmware error
|
|
Our class uses NiMH batteries. Haven't seen any problem... but we do have one problem off and on and I guess that could be related. On one RCX, we do get an error that the firmware needs to be downloaded quite often, and the battery level on the RCX (...) (23 years ago, 12-Jul-02, to lugnet.robotics)

(...) Definitely use NiMH's. NiCd's are a problem - they only generate 1.2 volts instead of the usual 1.5 of disposable batteries - and I've found that this *sometimes* causes problems with the RCX. I'm not sure exactly what the situations where it (...) (23 years ago, 13-Jul-02, to lugnet.robotics)

Does anyone have any comments about using rechargeable batteries in the RCX? Has anyone had any bad experiences with this? Can anyone recommend whether NiMH is better or worse than NiCd? Thanks. Laura (23 years ago, 12-Jul-02, to lugnet.robotics)
