How long do 8 AA NiMH rechargeable batteries last at 200 triggers a day?
Amazon Basics NiMH rechargeable AA (8-pack)

The pack holds about 18 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 | 21 |
| SD-card camera, 10 s video | 5.536 Wh | 3 |
| Cellular camera, photos, good signal | 2.950 Wh | 6 |
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 | 21 | 6 |
| 32F | 17 | 5 |
| 20F | 15 | 4 |
| 0F | 11 | 3 |
| -20F | 6 | 2 |
NiMH rechargeables are cheap to run once bought, but they sit at 1.2 volts, and some cameras read that as a low battery and shut down early. They also self-discharge and suffer in the cold. They make most sense in a camera you check often in mild weather.
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, 12 AA lithium, 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 8 AA NiMH rechargeable batteries last in a cellular trail camera?
At 200 triggers a day with good signal, about 6 days in our model, against 21 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.
