I have read articles here and there about charging Li-Ion batteries. Most of them try to solve the problem of maximizing capacity and also maximizing cycles. The most recommended method is charging with around .5C current until the battery reaches 4.2v and then switching to the constant voltage until the current gets less than a threshold and then stopping it.
I don't need the battery to be fully charged, even half the capacity of 250mAh battery can run my circuit for days, and the circuit is almost always using external power source. I want to see if using no control circuit, but offering a lower voltage, for example 3.7v and limiting the current to for example 50mAh will hurt the battery in long run. Minimum parts in my circuit is essential for me, so I would be glad if I could remove as much as possible! Thanks in advance.
