battery charging
Continued charging at 4.2 V, at any current, will gradually plate out the active material. You must stop charging completely when the charge current falls below a suitable termination threshold. Typically quoted thresholds are 0.05 C to 0.1 C, or 130 mA to 260 mA in your case, unless the datasheet for your cells says otherwise.
