10440 battery for k18

oppositelok · Aug 9, 2017

Hello All,

Can anyone recommend a good and by that I mean safe 10440 for my k18

Seem to be struggling to find any apart from Chinese sellers on eBay etc which I don't really trust....

Many thanks

Efest 10440.
Beware that the K18 overdischarges the li ion cells.
Be sure to recharge the 10440 as soon as you see the output fade.

I too use the Efest 10440 cells in my AAA lights. Haven't had any problems and great performance.

Seems like you may already have the answer above, but I think this thread will have more visibility in the "Batteries Included" subforum ....

I just checked, and I also have some KeepPower in the 145400 size which also are working quite well, so a 10440 cell from them should also be good.
