The AAA 1100mWh 1.5V Li-Ion rechargeable battery offers extended runtime for devices like flashlights, fans, and gaming peripherals. With a stable 1.5V output and 300+ recharge cycles, it outperforms alkaline batteries in high-drain scenarios. Its compact design and energy density make it perfect for wholesale integration into electronics requiring reliable, long-lasting power.
Eve Batteries in Electric Vehicles
How Does the 1100mWh Capacity Compare to Standard AAA Batteries?
Traditional alkaline AAA batteries average 850-1200mWh but degrade with voltage drops. The Li-Ion 1100mWh variant maintains a steady 1.5V until depletion, delivering 20% more usable energy. This “flat discharge curve” ensures consistent performance in devices like LED flashlights, where voltage stability impacts brightness.
Why Choose Li-Ion Chemistry Over NiMH for 1.5V Devices?
Li-Ion batteries provide higher energy density (400Wh/L vs. NiMH’s 220Wh/L) and lower self-discharge (2% monthly vs. 15-20%). Built-in circuitry in these AAA cells mimics 1.5V alkaline output, making them drop-in replacements without device modification. NiMH’s 1.2V nominal output can cause compatibility issues in voltage-sensitive electronics.
What Safety Features Protect Against Overheating and Overcharging?
These cells incorporate three-layer protection: 1) Thermal cutoff at 70°C, 2) Voltage monitoring (4.35V max), and 3) Current limitation (2C discharge/1C charge). The PCB includes redundant MOSFET switches for fail-safe disconnects during short circuits. EVE Battery’s patented CID (Current Interrupt Device) mechanically breaks the circuit if internal pressure exceeds 10kPa.
| Safety Feature | Activation Threshold | Response Time |
|---|---|---|
| Thermal Cutoff | 70°C | <0.5 seconds |
| Voltage Protection | 4.35V | 2 milliseconds |
| CID Activation | 10kPa | Permanent disconnect |
The multi-stage protection system works synergistically to prevent thermal runaway. During rapid charging scenarios, the voltage monitoring system samples cell potential 100 times per second, adjusting current flow through pulse-width modulation. This granular control enables safe fast-charging while maintaining cell integrity.
Differences Between Eve and Other Brands
Which Devices Gain the Most Benefit from This Battery?
High-drain applications see 3x lifespan improvement versus alkalines: gaming mice (50+ hours continuous use), LED bike lights (15hrs at 200 lumens), and digital cameras (400+ shots per charge). Medical devices like glucometers benefit from the stable voltage for accurate readings. Avoid use in clocks/low-drain devices where self-drain dominates.
| Device Type | Runtime Improvement | Cost Savings/Year |
|---|---|---|
| Wireless Mouse | 2.8x | $42 |
| LED Headlamp | 3.1x | $67 |
| Bluetooth Speaker | 2.5x | $38 |
In industrial applications, the battery’s vibration resistance (MIL-STD-810G compliance) makes it ideal for wireless sensors in manufacturing equipment. Field tests showed 98.7% uptime in vibration-intensive environments compared to 82.4% for standard NiMH alternatives.
How Does the Charging Cycle Impact Long-Term Performance?
Using a 500mA CC/CV charger extends cycle life to 400+ charges. Partial discharges (40-80% DoD) triple cycle count compared to full discharges. Capacity remains above 80% after 2 years with proper storage (50% charge at 15°C). The lithium iron phosphate (LFP) cathode minimizes dendrite growth, reducing aging from frequent charging.
What Certifications Ensure Global Market Compliance?
Certifications include UN38.3 (air transport), IEC 62133-2 (safety), and RoHS/REACH compliance. The cells meet MIL-STD-810G for shock/vibration resistance. Wholesale bundles include MSDS sheets and CE/FCC declarations. EVE Battery holds IATF 16949 automotive certification, guaranteeing <50ppm defect rates in mass production.
Can These Batteries Be Used in Extreme Temperatures?
Operational range spans -20°C to 60°C. At -10°C, capacity remains 85% of nominal via electrolyte additives (propylene carbonate). High-temp performance uses ceramic-coated separators stable up to 150°C. Storage at 45°C causes only 3% monthly capacity loss vs 8% in standard Li-Ion. Not recommended for below -30°C or above 80°C environments.
“The 1.5V Li-Ion AAA represents a paradigm shift. By eliminating the voltage mismatch that plagued earlier rechargeables, it finally makes sustainable power viable for mainstream electronics. Our testing showed 91% reduction in disposable battery waste for IoT device fleets.”
– Dr. Elena Voss, Power Systems Engineer at GreenTech Solutions
- How many charges can it handle?
- Rated for 300 full cycles to 80% capacity, but partial charging extends this to 500+ cycles. After 300 cycles, capacity typically measures 850mWh.
- Is a special charger required?
- Yes. Use only 1.5V Li-Ion chargers with 500mA max output. Standard Li-Ion chargers (4.2V) will damage these cells. Look for chargers with “1.5V LiFe” compatibility.
- What’s the shelf life when unused?
- 3-5 years when stored at 50% charge in 15-25°C environments. Self-discharge is <3% per month initially, increasing to 8% monthly after 2 years.
