The article, like you, does not even understand the difference between slow charging and trickle charging. A slow charge rate is C/10 ma and is what most wall mount chargers are designed for. It will fully charge a battery in 15 hours. It is a low enough charge rate such that it will not damage a batter if you leave it on longer unless it is for many days. A trickle charge is C/50 ma rate and is designed to just replace the charge lost through self discharge which both NiCad and NiMh batteries experience. Since they maintain the current charge of the battery and do not over charge it, there is no way a trickle charge will harm a battery. Like I said earlier, I charge at a slow rate when returning from flying for 15 hours and then switch to trickle charge until I next go flying. That way my batteries are always ready to go and they last for many years. If you are confortable charging and a 1C rate that is fine but I sure do not see any one else recommending that as a regular pratice.
