Default RE: battery charging

Dredhea,

<font size="2">

I don't mean to hijack this thread but maybe my questions can help the one who started it. My battery is a 4-cell 4.8 Nicd with 600 milamps. I did a cycling setting it to a low of 4.4 discharge. It took the charger 1 hour to discharge the fully charged battery to 4.4 at a rate of 0.5 amp. Is 0.5A a good average rate or should I go lower? The charging time was also 1 hour and it went up to 6.2 volts on the charger, but when I used my voltmeter under load (.5a) the voltage was 5.32. Is this more or less what I am supposed to get? Also, one last question, my instructor told me not to fly when my battery shows 4.78 or less under load (using the 0.5A in my voltmeter). Some people are telling I can go much lower. I am curious to know. Thanks.</p></font>
