Other Thoughts:This battery is rated 600mAh, but my 4sevens Preon 1 flashlight only draws ~200mAh before the battery can no longer power the light (I charged the battery to full at 0.1A rate after it runs dry, and can only put in less than 200mAh). The voltage is measured as low as 1V. Is there a protective circuit in this thing??
Pros:These lithium batteries 10440 of the flashlight I bought for E09 tank007 so small as to be protected batteries do not fit.
Their performance is better than I expected.
Loaded easily and fast.
The price is very good, but being four units.
They trusfire hologram original.
Other Thoughts:They could come with a box for storage.
