Which Arlo Camera Models Are Compatible with Tenergy 3.7V Batteries?
Tenergy’s batteries support Arlo Pro series (Pro, Pro 2, Pro 3), Ultra, and Essential cameras. To confirm compatibility, measure your camera’s battery compartment dimensions (typically 34mm x 20mm x 6mm) and verify the 3.7V requirement. Some third-generation Arlo devices may require firmware updates for optimal battery recognition.
For hybrid setups using older Arlo models like the original Arlo Wire-Free, consider voltage adapters. However, Tenergy explicitly recommends against modifying batteries for non-compatible devices due to potential short-circuit risks. Users with Arlo Go models (cellular-enabled cameras) should note these require different 4.4V batteries and aren’t supported.
| Arlo Model | Battery Type | Avg. Runtime |
|---|---|---|
| Pro 3 | Tenergy 2440mAh | 5-6 months |
| Ultra 2 | Tenergy 2440mAh | 4-5 months |
How Does Tenergy’s Li-Ion Technology Enhance Battery Life?
The 2440mAh cells employ nickel-cobalt-aluminum (NCA) cathodes, which provide 15% higher energy density compared to standard lithium-cobalt designs. This chemistry enables stable performance across -20°C to 60°C environments, critical for outdoor security cameras. Tenergy’s proprietary Battery Management System (BMS) actively balances cell voltages during charging, reducing capacity fade over time.
Real-world testing shows these batteries maintain 80% capacity after 400 charge cycles, outperforming competitors’ 300-cycle averages. The discharge curve remains flat between 3.7V-3.5V, ensuring cameras don’t trigger low-battery alerts prematurely. For best results, calibrate batteries by fully draining and recharging them every 6 months.
What Safety Features Are Integrated into Tenergy Arlo Batteries?
Beyond standard PCB protection, Tenergy incorporates multi-layered safety mechanisms. These include:
- Pressure-release vents for gas dispersion during thermal runaway
- Separator shutdown technology that blocks ion flow at 130°C
- Anti-aging electrolytes resistant to moisture degradation
The batteries undergo 12-point factory testing, including nail penetration and overvoltage simulations. Independent labs have certified their self-discharge rate at <2% per month, half the industry average for third-party alternatives.
“Tenergy’s multi-stage protection approach addresses both user errors and environmental extremes. Their separator film innovation alone reduces explosion risks by 70% compared to budget batteries.” — Dr. Emily Zhang, Battery Safety Researcher
Why Choose Tenergy Over Third-Party Alternatives?
Tenergy invests in ISO-certified manufacturing facilities with robotic assembly lines, achieving <0.1% defect rates. Their batteries support Arlo’s advanced features like 4K video streaming and integrated spotlights without voltage sag. Competitors often use recycled lithium cells that degrade faster in high-drain scenarios.
