  Re: Batteries?
 
(...) I have, with no problems so far - although I recall from the manuals that they're not recommended. The output voltage is lower than you'd get with standard batteries - but the savings are substantial! Cheers, Dominic. -- Dominic Hawken tel: (...) (26 years ago, 1-Dec-98, to lugnet.robotics)

  Re: Batteries?
 
re: rechargeables (...) That is the problem with NiCd rechargeables. By the time the battery low detector kicks in, it is often too late. And they have a 'memory' so you do want to run them down periodically. They are not recommended for the (...) (26 years ago, 1-Dec-98, to lugnet.robotics)
 
  Re: Batteries?
 
(...) NiCad "memory" is a myth. Long ago, nicads were much more sensetive to how they were charged, but their performance is a function of how they got the charge they're on, not on previous charges. Modern cells are far less sensetive than they (...) (26 years ago, 1-Dec-98, to lugnet.robotics)
 
  RE: Batteries?
 
(...) The Mindstorms documentation mentions somewhere that use of rechargable batteries is possible, but with reduced power. The later part probably refers to the lower cell voltage, as mentioned in another message: (...) (26 years ago, 1-Dec-98, to lugnet.robotics)
 
  Re: Batteries?
 
In article <3.0.3.32.1998120116...rdis.com>, Gary Hughes <ghughes@tardis.com> writes (...) Indeed yes - NiMh are much better. The main problem with them is that they have a high internal leakage. They are much worse than NiCads in this respect. So (...) (26 years ago, 1-Dec-98, to lugnet.robotics)
 
  Re: Batteries?
 
(...) Most everything that I've read on this subject argues that NiCad memory is mainly a myth. NiCads do get damaged by overcharging or deep discharging, but except in very controlled situations they don't have a "memory". I recommend reading (URL) (...)
