Hello-

My question is regarding charging a battery and ceasing the charge once the battery is full.

PROJECT INFO:
I am using rechargeable Li-Ion batteries in my device that will be rechargeable via an adapter that is plugged into wall outlet, then a cord will be plugged into my device which will be capable of charging the batteries I have inside.

My question is is there anyway to integrate a system into my circuit which is able to detect when the battery has been recharged and then it stops recharging. I want to prolong the battery life for as much as possible and I read that overcharging decreases overall battery capacity and life. Please let me know if you need any further explanation and thank you in advance for responding.

Agreed. Don't bother trying to implement your own charge strategy, like you might have gotten away with for lead-acid or NiCad batteries. A dedicated IC for the purpose is cheap, safe and effective.
