Hmm.... the button led on the Twist shouldn't stay on. It stays on with the Vision Spinner batts - only one I've seen that does. I'd check to see if the button is stuck first. Then if it's a Joye eGo-c Twist, you could try the 5 click on/off - that can tend to reset it. When charging it should act just like the eGo-c - the charger light is green, you put the battery on to the charger - just far enough to where the battery led flashes 4 or 5 times then goes out (don't over tighten) and the charger led goes to red. If that isn't happening and you just bought the Twist recently, I'd contact the vendor - after trying the 5 click on/off trick.
I have the eGo type
batteries(not VV) that came with the CE4 kit and the LED button is lit while charging. I thought that was odd at first. Now, I'm pretty sure these are knockoff
batteries - no logo or anything on them, just plain. So while charging, the charger light is red(blinks green) and the battery LED is lit. When charge is complete, battery LED blinks and goes off and charger light goes solid green.
I also have a SmokTech Winder VV battery and the LED button is lit while charging also and charger light is red(blinks green). But when charge is complete the battery LED blinks and goes off but the charger light continues to blink red/green for some time. If I leave the battery on the charger the light eventually goes solid green.
Is this just the difference in
batteries? I'm using the same charger for both batteries - the one that came with the eGo-CE4 kit (4.2v/420mA).
