Battery dying on a CREE XM-L2 Diving flashlight

Hi all,

I bought this flashlight: https://www.aliexpress.com/item/32825338582.html?spm=a2g0s.9042311.0.0.2...
and with the battery fully charged and the flashlight not in use the battry dies in around 20 days.
I don’t know how to find where the leak comes from.. Maybe is the dimmer?
You have any experience with this kind of issue? Any suggestions?

Thanks a lot.

Filip

Parasitic drain, all magnetic switch suffer. Just unscrew tailcap a little when you are outside of water:-)

Balls, wrote a whole reply, hit [preview] to edit it but never [save]…

 

Anyway, that’s normal.

See post #2 from here http://budgetlightforum.com/node/52132 .

The Hall-effect sensor drains about 10mA, so if using, say, a 5000mAH cell like my blue-wrapped LKs, that’s

5000mAH / 10mA = 500H

or about 20-21 days, spot on.

They lock out with a fractional-turn of the tailcap, so that’s what I do ‘til I need to use it.

Thanks for your answers! I will unscrew the tailcap and that’s all.
