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.
It''s actually very important to distinguish between rated energy and capacity, which are technically specified as watt hour (Wh) and amp hour (Ah), respectively. Despite what some may think, these values are not correlated. So, if a decision is made based on capacity alone, you might not end up with a suitable battery for your application
