I use the Kirkland cheap Costco batteries for spring, summer and fall months. They are cheap and work great. I switch to the Lithium batteries around the end of October (started this for the last two seasons) and have had pretty good luck with them, still not convinced that they work past -20 consistently. Tough to prove when your cameras are not taking pictures of animals when its cold unless you are out there.
As a note to the lithiums, I used these last year, labeled each group separately with time out in the filed and total pictures taken. All were reused this year and worked again from end of October until the end of January. I did have 4 brand new lithiums in two simmons trail cameras, they each took about 6,500 pictures before they died (Simmons trail cams worked until the end of November, then started taking pictures every 10 seconds until the cameras died 5-6 days later)
