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 …
