Can you trickle charge a lithium battery?

The capacity reached at 4.2 Volts per cell is only 40 to 70% of full capacity unless charged very slowly. For this reason you need to continue to charge until the current drops, and to terminate on the low current. It is important to note that trickle charging is not acceptable for lithium batteries.
