subject: Electrical Characteristics Of Rechargeable Batteries [print this page] Many types of cells, simply, the battery is a "save energy" devices. Can only be used once the battery can not charge the way through to add has been transformed out of chemical energy, it is called a battery. Batteries can be reused is called the secondary battery, or rechargeable batteries. Different electrical characteristics of each cell, but the rechargeable batteries, such as: nickel cadmium, nickel hydrogen, lithium ion battery, the electrical characteristics are similar. For the battery, but also understand the voltage, current and capacity of the relations and concepts.Laptop battery
The analogy with a water bottle, easy to understand the characteristics of the battery. Cc bottle is generally calculated as the number of the volume pot, the battery is mAh unit, to calculate the battery capacity. mAh unit, based on current (mA-mA) and time (h-h) of the product are calculated. Simply put, if there is a marked capacity NiMH battery 2000mAh, if the electric current 1000mA per hour "charge" into the battery HP Laptop Battery
TOSHIBA Laptop Battery, it can be about 2 hours battery full power. Although theoretically true, but all batteries are all composed of chemical materials, chemical reaction rate of a certain range, is affected by the length of charging time. At the same time, the battery charge and discharge through after successive capacity will be reduced. We often hear "the battery charge and discharge more than 500 times," meaning not the first battery 501 can not be used. Correct statement should be: the battery by fully charging and then fully back up is finished the number to 500 over 501 measurements and battery capacity, also marked the capacity of 80% or 60%, this is consistent with rechargeable battery quality standards.
