I just picked up my first dedicated weaponlight, an Insight M3, and in the manual it recommends to remove the batteries when your not gonna use it for awhile. I was hoping to leave it in the top drawer of the nightstand ready to go. Is it really necessary to remove the batteries if im not using it for weeks at a time? Do you leave batteries in your weaponlights for long periods of time, and have you had any problems?
with quality cr123s, I don't worry about storing them in lights for months without use.
Depends a lot on the batteries it uses. Lithium (such as cr123's, CR2032's, 2016's, etc etc) will not leak, therefore will not damage the light. Alkalines (AA's, AAA's, LR44's) will leak, will damage your light. Some other chemistries may vary. Weeks, you will be fine. Months, eh.
Thanks guys, its good to know my weapon light will be ready should I need it randomly in the middle of the night. It came with duracell 123s which I would think are quality, I'll probably use those up in a couple weeks just testing it out then I have some Surefire batteries that i'll use for long term storage.
CR123s are suppossed to have a 10 year shelf life.
I'm thinking this includes them being inside a flashlight.
Hell, seems like AAs, AAAs and such will go dead on you by the time you get home with 'em from your local Wally World.

CR123's and other lithium batteries have a 7 year shelf life. So do alkalines, if that tells you anything about the age of the batteries you buy from big box stores.
I've never known an alkaline to last that long on the shelf. And they damn sure don't last that long in a flashlight, camera or whatever.
Thank God Energizer came out with the Ultimate Lithium series of batts in AA and AAA. Those seem to last a good long while.
Ask Castrate about that, It was his flashlight battery that exploded in his gun safe starting the thing (with guns) on fire!

Check out a fresh set of Duracells, Rayovacs or Energizers. They typically have a use-by date 5-7 years after their manufacture date. But yes, Lithiums do MUCH better in flashlights, cameras and other high-drain devices. Now try and put them in your TV remote, that's a different story.
I have an XD with a viridian green laser/light. The gun typically sits on my nightstand as it is not my primary carry weapon. I have to replace the batteries every three months or so without regular use. I'll go to pick it up and the batteries are dead. I check it every week just to make sure even when not shooting it.
