Before you buy
Capacity (mAh)
Higher mAh means longer runtime between changes. For Arlo cameras, 1500mAh or above is recommended. Verified reviews show that 1400mAh batteries last 4-6 months, while 1550mAh can reach 8 months.
Temperature Range
If your cameras are outdoors in freezing climates, choose batteries rated for -40°F. Standard CR123A batteries may fail in extreme cold. Panasonic and Streamlight are top picks for low temperatures.
Shelf Life
All lithium CR123A batteries have long shelf lives (7-10 years). However, batteries stored in hot environments may degrade faster. Check manufacturing dates to ensure freshness.
The wrap-up
For maximum Arlo camera uptime, prioritize batteries with 1500mAh+ capacity and a wide temperature range. Energizer Ultimate Lithium offers the best overall performance based on verified owner reviews and specs.
Quick answers
Arlo cameras are designed for non-rechargeable 3V lithium batteries. Rechargeable CR123As (often 3.6V or 3.7V) may damage the camera or cause erratic behavior. Stick to primary lithium cells.
Depending on usage and settings, a quality 1500mAh battery typically lasts 4-8 months. Heavy motion detection or frequent live viewing reduces battery life. Verified reviews indicate 5-6 months is common.
Yes, CR123A batteries have a standard size (34.5mm length, 17mm diameter). However, some brands have slightly different diameters; check compatibility with your Arlo model. Most fit without issues.
