How to Charge a Li-Ion Battery Correctly and Safely

The recommended charging rate of an Li-Ion Cell is between 0.5C and 1C; the full charge period is approximately TWO TO THREE hours. In "1C", "C" refers to the AH or the mAH value of the battery, meaning if the Li-ion cell is rated at 2600mAH then the "C" value becomes 2600, or 2.6 Amps, which implies that it can be charged at its full 1C, or at 2.6 amps if required.
