My battery problems where not the battery but but the cover.
Trijicon has changed the o-ring on the battery compartment cover. The early models have a black o-ring the new one I just received is orange.
I have two SROs and both experienced battery problems and each time I called Trijicon they would instruct me to tighten the battery cover more. Finally after several calls I was told they changed the o-ring and they would send me a new battery cover.
So far so good.
