The 1.5V EVE AA Lithium-ion Battery (3400mAh) is designed for low-power household devices like remote controls, mice, fans, and alarm clocks. Unlike traditional alkaline batteries, it offers stable 1.5V output, USB recharging, and a 1200-cycle lifespan. Its lithium-ion chemistry ensures longer runtime, reduced waste, and compatibility with USB-C charging, making it cost-effective and eco-friendly.
What Are the Environmental Benefits of Rechargeable EVE Batteries?
One EVE battery replaces 300 disposable AAs, reducing landfill waste. Lithium-ion is 95% recyclable, and EVE’s 10-year lifespan minimizes resource extraction. Over a decade, a 4-battery pack cuts CO2 emissions by 48 kg compared to alkaline.
Manufacturing processes for EVE batteries also prioritize sustainability. The production uses 60% less water than standard alkaline battery factories and employs cobalt-free chemistry to avoid mining-related environmental damage. Local recycling programs accept spent units for material recovery, with 92% of lithium and 88% of steel components being reusable.
| Metric | EVE Battery | Alkaline |
|---|---|---|
| Annual Waste per Household | 0.3 lbs | 4.7 lbs |
| CO2 Footprint (10 Years) | 12 kg | 60 kg |
| Recyclability Rate | 95% | 40% |
How to Maximize the Lifespan of Your EVE AA Battery?
Avoid deep discharges; recharge at 20% remaining. Store at 40% charge in cool (15–25°C), dry environments. Clean contacts monthly with isopropyl alcohol to prevent resistance buildup. Use firmware-updated chargers to avoid voltage mismatches.
Temperature management is critical – exposure to heat above 40°C accelerates capacity loss by 15% annually. For long-term storage, place batteries in sealed containers with silica gel packets. Cycle batteries every 6 months if unused to prevent cell passivation. A 2023 study showed EVE batteries maintained 89% capacity after 5 years when stored at 20°C and 50% humidity.
| Practice | Impact on Lifespan |
|---|---|
| Partial Recharging (20-80%) | +300 cycles |
| Annual Contact Cleaning | +18% Efficiency |
| Storage at 40% Charge | Prevents Voltage Decay |
FAQs
- Q: Can I use EVE AA batteries in smoke detectors?
- A: Yes, but check if your detector supports 1.5V lithium. Some require 9V alkaline.
- Q: How many charge cycles does the EVE battery support?
- A: 1,200 cycles, retaining 80% capacity. Equivalent to 10 years of weekly charging.
- Q: Is it safe to leave the battery charging overnight?
- A: Yes, built-in IC stops charging at 100%. However, unplugging after 2.5 hours optimizes lifespan.
