Pros & Cons
Energizer Ultimate Lithium AA Batteries, 24-Pack
Pros
- The single biggest runtime upgrade for any AA trail cam — 2 to 3x alkaline life
- Rated -40°F to 140°F, so they don't die in a cold-snap when deer move most
- 15-year shelf life means you can stock up and store them
- Lighter than alkaline, which matters when you carry a dozen cameras' worth
- Steady voltage avoids the false low-battery warnings alkalines trigger in cold
Cons
- Pricey compared to alkaline up front
- Overkill for a low-traffic camera you check often
- A 24-pack only refills three 8-AA cameras
Spypoint Flex-M Cellular Trail Camera (Dual-SIM LTE)
Pros
- Only major brand with a genuinely free plan — 100 photos a month at no cost, forever
- Dual-SIM auto-carrier picks the best network so you're not locked to one tower
- Buck Tracker AI filters by species so your feed isn't 400 squirrel photos
- GPS location tagging built in for theft recovery and stand placement
- 28MP stills look sharp for a mid-priced cell cam
Cons
- AA battery life is weak — plan on the LIT-22 pack or a solar setup
- Video tops out at 720p, behind newer rivals
- Free tier fills up fast on a busy trail; you'll likely upgrade a plan
Our Verdicts
Energizer Ultimate Lithium AA Batteries, 24-Pack
If your cameras run on AAs, these are the upgrade that fixes the most complaints — dead cams in the cold and constant battery swaps. Buy them for any camera you can't check often.
Spypoint Flex-M Cellular Trail Camera (Dual-SIM LTE)
The smart value entry into cellular: the free 100-photo plan lets you try cell scouting with zero recurring cost. Just buy the rechargeable pack or solar — the AA appetite is the real catch.
