Default Duracell 1432 Flashlight: Battery Drain.

I purchased a 3 pack of the model 350 at Costco. Everyone one of them has this issue. 3 months is about right. Put new batteries in all of them and a few months later they all are virtually drained of battery life.

This is a common problem with the electronic switching.

google flashlight parasitic drain

A flashlight that's dead when you need it is worthless.
Take 'em back to Costco.

Newer flashlights advertise "no parasitic drain".
Get one that explicitly states that. Anything else is a crap shoot.
