What ohms would safely drain most phone batteries?
simoV8 said:Nigel , is the safe discharge for batteries worked to a percent of full charge ( eg . a new car batt fully discharged a few times seems to wreck them ) ,,?? .. Also a mate of mine got a mobile phone the same as mine ,(same shop, one day later , and his batt died a few months ago and mine's still goin strong ),(touch my head)..
stevez said:I wonder if a zener diode in series with a resistor wouldn't provide the discharge capability and some protection from taking the battery down to nothing. Resistor would have to be selected with the power handling ability of the zener - don't forget the power rating of the resistor itself.
