Conclusion
I have tested this battery a few years ago and it has not improved with time, it is slightly worse.
It is a bad battery, with wrong specifications. It is cheaper to buy good batteries!

I guess, the motto of their sales department is: there’s a sucker born every minute.
Thank you Henrik, for your efforts in preventing that I (we) might be the next one.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

What was that about “Anything with FIRE in the name??.”
BLF Coupon prices etc give access to decent battery’s at good prices.
WHY would you even bother with the Chinese ones?.

I’m quite pleased with my SOSHINE actually. 26650/14500 and 10400?(AAA)
Better than expected.
But the NCR Panasonic 18650 and Samsung Q30’s do me fine. they NOT exxy on coupons. and do all the torches I use.
It’s hard to get decent battery’s here without paying full Aust pricing. Expensive.
