Hi, Can anybody confirm whether recharging a NXT battery block using 9V or 12V DC adapter is a bad or good idea, please? Seems that LEGO published HW schematics for the brick, but not for the battery block... Pavel. (17 years ago, 30-Nov-07, to lugnet.robotics.nxt)

(...) I'd say a bad idea, since it's supposed to be supplied with 9-12V *AC* (not DC) power. Like the RCX 1.0, it might work under a DC supply... but that's not what it was designed for. (17 years ago, 30-Nov-07, to lugnet.robotics.nxt)

My NXT Charger came with my battery. The output of the charger is 10.8 volts, 700 ma 8W. I would just buy the Lego charger. After reaching a full charge, the charger goes into a trickle charge mode.

(...) You should. The NXT battery expects the same wallwart as the train controller and RCX. Philo (17 years ago, 30-Nov-07, to lugnet.robotics.nxt)

(...) Whew! I was going to put my question in past tense ("Does this mean that I should have or shouldn't have used the train controller plug ...") but it seemed better to be a fool after doing something not dumb than after doing something dumb!

(...) The reason asking is that sometimes we send teams of students to a country with different voltage in the outlet, i.e. 110V instead of 220V, and the LEGO adapter accepts 220V, but not 110V. However, we have a DC adapter that accepts both 110V (...) (17 years ago, 20-Dec-07, to lugnet.robotics.nxt)
