>They can't keep counterfeits off (I just recently got a 'samsung' battery that would only charge to 80%),

Are you sure that it is counterfeit? 80% is a common charging cutoff point for Li-ion batteries to minimise wear-and-tear. Usually it is enforced in software.

They're shipped at 60%, though any charge cap would still be reported as 100% by the logic in the battery. I know my MacBook doesn't say 80%: Full! ;)

But my Thinkpad does say 80% full, because I've (deliberately) capped the battery charging at 80% to prolong the life of the battery.

So you're charging only to approximately 64% of the actual battery capacity?

No, I'm charging to 80% of the battery capacity.
