Trail camera battery life depends on several factors that drain power at different rates:

• Each photo trigger uses approximately 0.5-1.5 mAh depending on flash type
• Video recording uses 10-50 mAh per clip depending on length and resolution
• Cellular transmission is the biggest battery drain, using 30-100 mAh per transmission
• Cold temperatures reduce effective battery capacity by 20-50%
• Standby mode draws approximately 0.1-0.3 mAh per hour

Our calculator uses average consumption data from popular trail camera models to provide realistic estimates. Actual results vary by camera model and conditions.
