How long does it take to charge a lithium battery?

It is not difficult to know more about lithium battery charging time. Clarifying the lithium battery source of the charging time will help make it more scientific in theory and in practice.

In theory, lithium battery is nominal capacity battery charging time and the ratio of the current:

Lithium battery charging time (h) = battery capacity (mAh) present charging current (mA)

But, due to impedance when charging, in order to offset the effects of impedance, the actual charging time, charging time than the above theory in order to make the lithium battery can satisfy the demands of actual full recharge time, generally according to the charging current of battery capacity ratio of the coefficient of the size of the set a is greater than 1.For example,

When the charging current is less than or equal to 5% of battery capacity coefficient is 1.6, at this time

Lithium battery charging time = x 1.6 battery capacity present charging current

By analogy, according to the size of the charging current of battery capacity proportion, lithium battery charging time and calculation of coefficient

1.5 (5% < charging current 10% or less),

1.3 (10% < charging current 15% or less),

1.2 (15% < charging current 20% or less),

1.1 (20% < charging current).

Practical, portable electronic products lithium-ion battery charging time is designed, according to the above formula for the lithium batteries are usually equipped with corresponding constant current charger, this kind of lithium battery charger for lithium battery charging time is a full charge indicator light to indicate that the control of a full charge will send alarm signal, so that consumers only need to in accordance with the instructions to go, do not have to worry for lithium battery charging time long before the right.
