Anyone else get that bad of performance? Weren’t they talking 5 plus years?

Did you put a fresh battery in to start? The one in the blister pack might be craptastic. Also, the whole motion activated stuff for a carry gun can be problematic to battery life. Even so, less than a year sucks.

Yeah hopefully it was the craptastic one that came with it

The battery in my Romeo I Pro didn't last a month after I got the gun. It was crap on my 3rd or 4th outing with the gun. The replacement battery has been pretty good since then. And who really knows how good a battery it was, or how long it sat or was fondled before I brought the gun.

There's a thread running on Pistol Forum where a user is running various batteries (2032s 8n this case) through some Aimpoint T2s set to add left on max brightness to see how they stack up. The answer is to buy Duracell.

It's entirely possible the Sig stuff is just burning them that much faster, but Duracell can be had for less than $1.25/battery from Battery Junction.
