    Reasons and Precautions for 0V or Low voltage Battery
    Reasons of 0V or low voltage battery are as below:   a. External short circuit or over charge, opposite charge/mandatory over discharge.   b. High continuous current over charge, battery cell swell, cathode and anode poles connected which causing short circuit directly.   c. Internal short circuit or micro short circuit, e.g. cat...

    Is Carbon Battery Rechargeable?
      Many people ask, whether carbon battery is rechargeable? The answer is for sure, no. Carbon batter is primary battery, and dry battery is non-rechargeable.   There are two types of AA/AAA battery, rechargeable and non-rechargeable.   Non-rechargeable AA/AAA battery includes carbon battery and alkaline battery, carbon battery is ...

    Ni-MH battery purchasing tips
    When you purchase Ni-MH batteries, do not judge them by their capacity. For example, many people will choose 1200mAh battery when they need to make a choice between a 3.6V 1200mAh Ni-MH battery and a 7.2V 900mAh one because people think that higher capacity means that the battery can release more electricity in an hour. But it’s not true. ...

    Maintenance and Apply of Ni-MH Battery
    Usually a new Ni-MH battery only has a low electricity volume. When purchased, it requires charge before use.   New purchased Ni-MH battery performance will be in a best status after 3-4 times’ charge and discharge. When you charge the battery for the first time, its capacity may not be as much as you imagine, but this problem can be solved...

    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...

    Appropriate Electronic Product’s Batteries
    How to purchase appropriate battery for electronic products? a. Firstly, choose battery type and size according to electronic product requirements, and decide to choose what kind of battery, rechargeable or non-rechargeable according to power consumption and features of electronic products. High-power consumption product, e.g. MP3, digital camer...

    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...

    Battery’s Brief Development History
    In ancient time, similar battery device appeared, but the first recognized battery is Volta, which becomevoltapile in 1800 by using different metal and electrolyte.   In 1839, W.R. Grove published the first report about fuel battery research in the world.   French Plante firstly developed lead acid battery, and became commercialization...

    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...
