I have the battery for a NiteCore SRT3 ordered where he fits purely fortunately.
Only the negative is completely wrong glued battery case on what the battery useless for my NiteCore Sense CR makes with twist lock because the battery not nearly reinpasst.
The protection circuit is also not the best, but at least this works. at 2.9V cell voltage disconnects the current flow. since I know other brand batteries of this size which enable the protection circuit at 3.3V, is permanently acceptable for the battery.
The battery has also measured (loaded 790mAh, 733 mAh discharged) a slightly higher capacity than my Tensai 600mAh and so I am happy for my EDC Light, but no more
