What is the correct charge and discharge method for lithium battery? What are the precautions in the usage of lithium batteries?

The correct charging methods of lithium battery:

(1) standard charging method: 0.2 C5 constant current charge to battery voltage of 4.20 V, instead of constant voltage charging, and charging current < 0.01 C5 is considered.

Charging standard is often used to calibrate the battery capacity, due to the charging too slow, is rarely used in daily use.

2: fast charging method with 1 C5 constant-current charging to the battery terminal voltage of 4.20 V, instead of constant current charging, and charging current < 0.01 C5.

Fast charging method of notice:

(1) the initial charging current cannot too big, lest battery overheat, leakage, burst occurs.

(2) the voltage of the battery arrived at 4.20 V, must immediately turn to constant voltage, the voltage to demand higher error (< 0.5%), must use more than four and a half multimeter measurement.

Lithium battery discharge method:

Method: (1) standard discharge to 0.2 C5 electric constant exile to the battery terminal voltage of 2.75 V.

Because it is difficult to meet the daily use of this condition, so the meaning is not big, this method is mainly used to calibrate the battery capacity.

Quick discharge method: [2]Lithium ion batteries resistance is very small, so allow large current discharge, at room temperature, with 1 c5 can discharge current discharge 54 minutes (more than 90%);1.5 C5 discharge time more than 30 minutes;2 c5 discharge time more than 23 minutes; More large current discharge and allow for short.

The matters of attention in the lithium-ion batteries used in mobile devices

The charge and discharge problems occurring in the use of lithium battery cell phone in one of the most important tip:

1, according to the standard time and procedure charging, even three times before, so will put the charger (line) filling plugged in and then to the output of the charger with mobile phone charging port (charging switch machine are available)

2, when there is a hint when battery power is too low, should try to start charging in a timely manner; The lithium battery in the case of over discharge is the easiest damaged!

3, the activation of the lithium battery does not need special method, in the normal use of mobile phone lithium batteries will naturally activation.
