How long do 12 AA lithium batteries last at 200 triggers a day?
Energizer Ultimate Lithium AA (8-pack)
$11.99 listed price, changes often See it on AmazonHow long does 12 AA lithium last by capture mode?
The pack holds about 48 usable watt-hours at room temperature in our model. Half of the 200 daily triggers are assumed to come at night.
| Setup | Energy a day | Days |
|---|---|---|
| SD-card camera, photos | 0.836 Wh | 57 |
| SD-card camera, 10 s video | 5.536 Wh | 9 |
| Cellular camera, photos, good signal | 2.950 Wh | 16 |
At 200 triggers a day this is a busy spot: a feeder, mineral site, livestock area or a road. Lengthening the delay between triggers is the cheapest way to extend battery life here.
How much does cold weather shorten it?
| Temperature | SD-card camera, days | Cellular camera, days |
|---|---|---|
| 70F | 57 | 16 |
| 32F | 56 | 16 |
| 20F | 55 | 15 |
| 0F | 52 | 15 |
| -20F | 49 | 14 |
Lithium AA cells are the standard for trail cameras: highest energy, flat voltage under load, and about 90% of capacity at 0F. The higher price per cell is repaid in fewer trips and fewer dead cameras in late season.
Same pack, other trigger counts
5 a day, 10 a day, 20 a day, 35 a day, 50 a day, 100 a day. Other batteries at 200 a day: 8 AA alkaline, 8 AA lithium, 8 AA NiMH rechargeable, 6 AA lithium, 12V 7Ah external battery.
These are engineering estimates for comparing setups. Real cameras differ by roughly 40% either way depending on the model, IR array, signal strength and firmware.

Frequently asked questions
How long do 12 AA lithium batteries last in a cellular trail camera?
At 200 triggers a day with good signal, about 16 days in our model, against 57 days in an SD-card camera on the same pack. The cellular radio's standby and uploads are the difference. Weak signal (one or two bars) cuts it further, because the camera retries uploads.
What drains trail camera batteries fastest?
In order: cellular uploads on weak signal, video clips at night, infrared night photos, and a busy spot that triggers hundreds of times a day. Cold weather then shrinks whatever capacity is left, especially with alkaline cells. Lithium AAs, photo mode, a longer delay and a spot with better signal all extend runtime.
