MotorCityGun:
It's "2032"
.... They were passing out a coupon when the promotion started. Asked for a copy of something (sales slip?). Then (you're correct), you call.... Can't find the fool number, naturally
....
(I did get a couple sets originally. Ain't gonna say what happened to those
....)
Actually, they fit Sammy's "don't bark" collar.... I bought him one that senses barking, and is supposed to make a nasty noise if he does. He
liked it! Like a kid with a bike siren! The next one, the one that uses those batteries, depended on me to press a button. It would make some nasty noise, or shock him a little, at my choice. It worked somewhat.
Anyway, at least with my CT lasers, unless I'm playing with the cat with it (EMPTY the fool gun!), service life seems to be nearly infinite. I shoot once a week, and rarely use the laser, but visitors seem to fall in love with it. The only trick to remember (at least for me) is to shut the thing off before putting the gun into some sort of storage where the button could be pushed by the packaging.
("2035" won't fit - it's about twice as thick - but you can use a 2032 in many applications that call for it - less current available.)
I'm sure you can find a rechargeable version, but given the pain involved in recharging it for a CT laser, I'm not sure it'd be worth it.
DON'T lose that little allen wrench.... Lord knows where you'd get another one "over the weekend"....
Regards,
