Correct charging current for lithium-ion batteries
This target charge current is relative to the battery capacity ("C"). For standard Li-ion or Li-polymer batteries, chargers often target 0.5C charge current. In other words, if the battery is rated at 500 mA-h, the target current is 250 mA. It is not unusual to charge at 1C (500mA), but this compromises the battery''s capacity over time.

battery charging
In case when detailed specifications (like this one) cannot be found, the rule of thumb is to charge NiMH batteries at 0.1C (C=rated capacity). 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.
What amount of current should I use to charge a 12V car battery?
There is a rumor unspoken rule : the slower charge the better battery, it seems charging current is around C/10 and <= 10A is more favourable to prolong lead acid battery. However, better read the battery specs and datasheet to find out. Example: Your battery capacity is 80Ah, C/10=8A <= 10A, then maximum charging current is 8A.
