subject: Do Not Use Too Much Of The Current Battery Charge And Discharge In Order To Avoid Overheating. [print this page] Ni-MH battery and lithium battery can not overcharge resistance. Therefore, the Ni-MH rechargeable battery to a constant current control mode PICK CUT highest in the charging voltage, the stop to continue charging the charge for the best way. The lithium batteries used constant current, constant voltage charging mode the best, if nickel-cadmium battery charger-DV control the way the words of the Ni-MH rechargeable batteries and lithium batteries.

Nickel-cadmium battery is changed by chemical substances and chemical reactions with each other to carry out the conversion of electrical energy. As the nickel-cadmium batteries in the slow response of chemical materials and self-consumption, if the temperature is high, then its self-consumption will be more severe form, nickel-cadmium batteries will gradually reduce the capacitance, it is very possible rust or leak liquids such phenomenon. At the same time in the case of high temperature, charge and discharge it if more of its battery life will be affected. Compared to other batteries, nickel cadmium batteries can be wider temperature range, the charge temperature to zero degrees Celsius to 45 degrees Celsius more between the discharge of the regional space is wider, about 20 degrees below zero to zero at 60 degrees , usually pay attention to the preservation of the environment on the dry and low temperature, so more conducive to the maintenance of nickel-cadmium batteries.
Nickel-cadmium battery's internal resistance is very low, generally only a few cents to tens of milliohms or so ohms, so the size difference between external load is very stable discharge voltage, discharge current curve is very flat, you can enlarge the current discharge. General dry battery internal resistance tens of ohms, the discharge voltage instability in the discharge current curve is not flat, compared to nickel-cadmium batteries are the ideal characteristics of the battery.
Therefore, unless the use of nickel-cadmium batteries is heat resistant, and otherwise monitor the battery charge and discharge when the temperature, do not use too much of the current charge and discharge in order to avoid overheating. Temperature for the battery life and charge-discharge characteristics are greatly affected if the ambient temperature when charging and discharging the higher, the battery material is damaged, very functional version of the active substance reduces the capacity to reduce the anode cathode separation between isolated Edition short circuit caused by insulation reduced version, and the temperature becomes low battery voltage, charge and discharge efficiency reduces the number of the battery's capacity greatly reduced. rapid charge current is about the size of the general about 0.3C to be able to 4 6 hours to complete charge, and now some ultra-rapid type of cell, able to 1.5C or more ultra-rapid charging current to do, in less than an hour to complete a very short period of time charging action. laptop battery
