How much should I charge my 11.1V battery?
Your battery is rated with a recommended charge current of 1,5A (or 1C as we call it) so you want to set up your current limiting at 1,5A maximum. After charging at 1,5A the pack voltage will slowly rise to 4,2V per cell (12,6V in total for 3S pack) and at this point the charge current is to be turned down to zero gradually. Charging a cell over 4,2V is very unsafe …

Therefore, for a typical AAA rechargable 1.2V battery with typical capacity of 800 mAh, the charge current should not exceed 80 mA, so the 500mA is a clear overkill, literally. For AA with 2500mA typical capacity the charge should be done at 250mA, but 500mA could be fine (0.2C rate). Unless the battery cell is designated as "rapid charge", when the charge current …
