Ni-H¡¢Ni-Cd Charger
 
[NO PICTRUE]
 
 
 
Function£º
 
* Can charge four pieces of Ni-H,Ni-Cd rechargable battery, can charge 1, 2, 3, 4 alone too.
 
* Have battery short detect function , avoid damage the charger;
 
* Adopt - ¡÷ V(negative voltage) measuring and temperature measuring , can make the battery charge totally full.
 
* Judge that it is not a rechargeable battery;
 
* Restriction of the maximum charge time;
 
* After Battery charge fully adopting tiny stream, guarantee that the battery is the full electric consumption
 
-- at the charger;
 
Working course£º
 
* No putting battery, 4 indicator lamp go out all,when putting battery,The corresponding indicator lamp is lighted;
 
* The big current charge:
 
--Carry on with 300MA with 500MA current to charge battery pulse, and measure the voltage and current of charging
 
--at any time;
 
--A:If measure and have got voltage up to 1.55 V within 3 minutes, judge  battery is non-rechargeable , Stop
 
-- charging,and the indicator lamp glimmers  with 5HZ frequency, time marks zeroing , The battery is taken out,
 
-- then the indicator lamp goes out;
 
--B:If measure and get voltage under 0.5 V within 3 minutes, judge battery short , Stop charging,and indicator lamp
 
-- glimmer by frequency with 5HZ, time marks zeroing ,  The battery is taken out, then the indicator lamp goes out;
 
--E:According to feedback voltage after charging 3 minute, go on - ¡÷ V( 5 15 mV, E: of mV,) measure;
 
* The tiny stream flows charge:
 
--If - ¡÷ V meet the demands, change charge pulse width , carry on tiny stream charging, Charging about
 
--10mA electric current, indicator lamp glimmer with 1 HZ frequency,indicate that the battery has already been full;
 
* Shut off regularly:
 
--Time from start charging, stop big electric current charge after 5 hours, change switch to tiny stream flow
 
--state of charging, The indicator lamp glimmers with 1HZ frequency;
 
* Taking out the battery, then the indicator lamp goes out;
