TONSHEN LCD Quick Battery Charger for AA / AAA Ni-Cd Ni-Mh Rechargeable Batteries The charger can charge 1-4psc AA/AAA Ni-MH/Ni-Cd rechargeable batteries,Each hour 1500mA, Each slot independent display. Charging by IC control, tieh-AV intelligent cut off the rapid charging function,automatic transfer to tricke-charging,insure ssafety usage.The LED will be on and show its background for 2 seconds afterconnected with the power source, then off. There is letter "CHG" showing on LCD after battery loaded, the word "ERROR" which means defective or non-rechargeable battery loaded would be shown on the corresponding posititon on the LCD if such kind of battery loaded, and the coressponding battery photo would flash. Refreshing battery function, if the battery voltage getting less(0-0.9V), charger can refresh the battery. Short-circuit protection, avoid the battery polarity "+/-" short-circuit protect.worldwide voltage, sutiable for the whole world.power by cable and the cable is about 120cm in length, Allowing you to charge you batteries more conveniently. The charge is intelligent,It can at the same time charging of AAA and AA batterys or Ni-MH and Ni-Cd.Trickle Charge process and simple repair abandoned rechargeable battery.You can check charging through the LCD display.Can be compatible with almost all AA/AAA Ni-MH/Ni-Cd batteries. The charger can accept 100 v to 240 v voltage,Apply in the world the vast majority of countries.Each country voltage is not the same,If there is no through pressure device directly using the equipment, will be short circuit or destroyed,The charger canPerfect accept the voltage ofeach country,Travel or work outside can use it, when you return to the home, still can continue to use it,You don&#039;t have to worry about use battery equipment without electric power anddon&#039;t need to prepare two battery charger in order to adapt to abroad. Small and portable,pressure equipment and charging equipment set to one body,don&#039;t need to carry the heavytransformer for yourexpensive equipment,We think youmoredon&#039;t want to razor or camera cannot be usein the key time,Take it, all these problems can be solved. Input:100V-240V AC 50/60Hz At the same time charging 1-4 AA/AAA Ni-MH/Ni-Cd rechargeable batteries LCD displays charging progress for each battery Independent monitoring each battery slots When charging is completed,Automatically stop charging Temperature monitoring,When the temperature &gt; 60,Shut off the power to prevent accidental Intelligent control prevent over charging Auto identification waste battery,try to repair Automatically detects battery status and selects the appropriate voltage and charge mode Size:114mm  75mm  30mm Weight:96g Output:1.2V DC 1200mA AA1200mA x 1 AA600mA x 2 AA300mA x 3 AA300mA x 4 AAA600mA x 1 AAA300ma x 2 AAA150mA x 3 AAA150mA x 4 20% of the startusing slow charging fortest batteryavaila bility and ensure the stability of the battery,After will use large current charging, quick charging 95%,The final 5% using eddy current charging, to make sure that battery electricpower tomaximum value. If the battery has problem, it will try to repair the battery by changing the current,for waste battery(voltage0 ~ 0.9 V)proceeddeep cycletry to repair. Complex structures in order to ensure its stability and charging effect.But one thing I must tell you.Please don&#039;tcharging to con&#039;trechargeablebattery,this can cause serious consequences even fire.For example, carbon batteries We through experiments prove,if the alkaline batteries for charging for many times,can cause alkaline battery was completely destroyed and even cracked. Because of these reasons above,the charger has a additional function is the short circuit protection,if the temperature is too high or the battery can&#039;t afford theelectric current, the charger will automatically shut off the power. Battery belong to dangerous goods, please use caution.
