Strange Batery Behavior

[J.Oddino]

Sounds like a bad battery but the most significant revelation is that your independent check lied to you.  If you can attach a voltmeter while you have it on the cycler you will probably see the voltage drop as soon as you apply the discharge load.  Once again, you can't tell the state of charge by reading voltage.  You need a charger that tells you how much it put in.  You also need to cycle it periodically to know that it is a good battery.

  I was out practicing this last Monday when I noticed the lights on my volt watch doing what I thought was strange stuff.  So I stopping flying and went home.

  I put the plane on the cycler and charged the Ni-cds on the cycler.  Next morning independent check showed the battery as full charged and no flickering lights on the volt watch when I turned the plane on.  So far - go good, so I thought it might be good to cycle the batteries a couple of times just to make sure things are working.  When I push the dis-charge button the plane immediately goes back to full charge.  I cycled two other batteries to check the cycler out and it seems to be working.  So is the battery in the Focus safe to use?
