Lithium ion charging
The "constant voltage/ constant current" method is used to charge Lithium ion batteries (See figure below).
- Charge Voltage
The maximum voltage is 4.2V x the number of cells connected in series. - Charge Current
We recommend 0.7 CmA.
When the voltage per cell is 2.9V or less, charge using a charge current of 0.1CmA or less. - Charge Temperature
The batteries should be charged at temperatures between 0°C and 45°C. - Reverse-polarity Charging
Verify the polarity of the batteries before charging to insure that they are never charged with the polarity reversed.
