Where did you read these reports? I recall reading that these batteries tested out just fine by one of our reviewers not long ago.

When the Trustfire new Flame just hit Manafont, Stephen Wallace's review seems not bad,

However, after some time some guys have some complaints. All the bad comments are from HKJ review here,

And here is an issue face by Aleister, the protection circuit failed to kick in,

EDIT: Stephen Wallace's Trustfire 3000mah Flame is not from Manafont but provided by someone from Ebay, while my Trustfire 3000mah Flame are bought from Manafont. Not sure if this does matter though (quality variation?).
