When the light stops blinking is it done charging? I know it is supposed to but if I take the battery out and put it back in it starts blinking again. I will be purchasing a better charger/batteries but I dont mind using this one as well if it isnt broken.
I'm with the Lady here. There were a lot of different models (I think I have at least two I never use...).
What you report, taking a 'charged' battery out and putting it back triggers charging again, is very common. Watch it for a few minutes it may trip out again, it might not. This is, however, not a smart thing to do. NIMH chargers primarily use 'negative delta V' to control charging. Strange as it seems, if you put fixed charging current into them the voltage slowly rises (no surprise here I hope?) but at the very end of charge two things happen, the battery heat takes a quick rise and the voltage
drops a little bit. Typically something like .03 Volts IIRC. This is Negative (going down) Delta (change in) V (Voltage) detection. If you 'bump' it enough times it gets past that point and no detection happens and it can get bad for the battery. BTW, most chargers also include a very minor trickle current charge that does two things, keeps the battery topped up (not really the best for them but convenient) and it can 'unlock' depleted batteries in chargers that don't detect them automatically. This current is small enough to not cause problems with detection of course.
So if the lights make sense, and the battery is getting stronger, I say go for it. But don't take 'em out and put 'em back in very often?
