I'd imagine the tolerances were/are MUCH higher with cheaper HK manufacturing processes that aren't under (more?) stringent Nokia QA tests.

Most OEM batteries are sold as being XXmAh capacity which to me implies a minimum target of XXmAh. Most HK batteries are sold up-to XXmAh which to me implies a maximal XXmAh [more than likely - they'll work out theoretical maximums given battery volumes and don't actually test the real capacity at all!] with no minimal capacity at all!


My qualitative experience of replacement HK mobile phone batteries for the Motorola, Nokia and Sony Ericsson phones wasn't good in _all_ cases - they simply didn't stack up to the original equipment at all.


That's not to say they weren't good value for money though they were just not as good capacity wise! For the best bang-to-buck ratio you'll need to compare capacity vs cost.
