Flashlight anti-battery-rattle device (ultra-cheapo)

Flashlight anti-battery-rattle device (ultra-cheapo)

Dimensions of the same type of battery vary from manufacturer to manufacturer, so flashlight factories often make battery tubes slightly wider than necessary, to accomodate any battery brand that you may come across. The result is an unpleasant rattle.

Here's the simple and ultra-cheap solution to this problem, which I've put to use with my 1*AAA and 1*AA Fenix flashlights.

What you need is: PET plastic beverage bottle (beer, soda, whatever) of preferably regular cyllindrical shape, scissors and (optionally) a hollow punch. Cut out a patch of plastic (as flat and even as possible), and trim it with scissors to fit around the battery. Cut out holes or recesses if you like (not really necessary, but looks smarter, hehe) and bend plastic into cylindrical shape. Place the plastic around the battery and insert together into battery tube (don't apply force or yo'ull end up with a stuck battery!)

My favourite shapes are these:

This is how finished "Type 2" anti-rattle looks like (flashlight is Fenix LD15, plastic is from a beer bottle and it is actually a laminate so it is possible to adjust thickness if needed):

I also have "Type 1" installed in Fenix LD01 and E01 (made of thinner plastic).

PLEASE NOTE: this device, although perfectly suitable for an EDC use, may interfere with quick replacement of batteries in a high-stress environments (emergency services, police and military use) so I don't recommend it for such uses.

Cheers,

Tam

Thank you very much! Smile Seems simply and useful.

Just a question: why do you use "I" shape instead of a normal cylindrical one?
