    AA Dry Battery Discharge Current
    AA dry battery load current depends on load resistance (I=U/R): the higher the load resistance, the lower the current, vice versa. Therefore, there is a largest limit current for AA dry battery, it will damage or shorten lifetime when above this value.   AA dry battery work time depends on discharge current, that load and battery internal r...

    Differences between Carbon and Alkaline Battery
    The difference between carbon and alkaline batteries include, a. In terms of material, both carbon battery and alkaline battery are dry batteries. b. Carbon battery is carbon zinc battery, also called zinc manganese battery. It is a most common dry battery and features low price, high safety and reliable. Yet it contains heavy metal cadmium, whi...

    Common Sense on Applications of Lithium Ion Batteries
    a. It should use special battery charger to charge lithium batteries. It takes CC/CV charge method, that is, charge with constant current, then transfer to constant voltage charge when voltage is up to 4.5V, stop charge until charge current declines to 0.01C. Charge voltage: max charge voltage is 4.2V*n (n is the number of series connection) Cha...

    Rated Battery Capacity
    In deigned regular condition (temperature, discharge rate, cut-off voltage etc.), the minimum capacity battery can discharge, unit Amper Hour, sign for C. Capacity is affected by discharge rate, so number following C represents the discharge rate, for instance, C20=50 stands for 20 hour rate capacity is 50 Ampere Hour. Theoretical battery capaci...

    Durable Alkaline Battery
    Why alkaline battery is durable? Alkaline battery, also called alkaline zinc manganese dry battery, compared to regular dry battery (carbon battery), is durable, large current, long storage life, shell resistant to corrosion etc. Alkaline battery uses opposite electrode structure, which increases relative volume between cathode and anode. Beside...
