The 1.5V 5000mWh C Size LR14 Li-po Battery combines lithium-polymer technology with Type-C fast charging, offering 3-5x longer lifespan than alkaline batteries. Its stable 1.5V output maintains consistent performance in high-drain devices like gas igniters and LED flashlights, while USB-C charging enables full recharge in 2.5 hours. EVE Battery’s proprietary cell design prevents voltage sag common in standard lithium batteries.
How Does Lithium-Polymer Technology Enhance Battery Performance?
Li-po chemistry enables ultra-thin electrode designs with 27% higher energy density than standard lithium-ion cells. The laminated structure reduces internal resistance to 45mΩ, maintaining 1.5V output until 95% discharge. This contrasts with alkaline batteries that gradually decline from 1.5V to 0.8V. EVE’s hybrid electrolyte formulation prevents dendrite growth, enabling 1,500+ cycles at 80% capacity retention.
What Safety Features Protect Against Overcharging?
The battery integrates three-layer protection: 1) Current-interrupt device (CID) activates at 4.35V±0.05V, 2) Positive temperature coefficient (PTC) resistor limits current to 2.8A during faults, and 3) Battery management system (BMS) monitors cell balance with ±15mV accuracy. The flame-retardant casing withstands 130°C without deformation, while the CID permanently disconnects at 150kPa internal pressure.

Which Devices Benefit Most From This Battery Type?
Optimal for devices requiring sustained high current: gas cooker igniters (3-5A pulses), medical flashlights (20lm/W efficiency), and wireless security sensors (10-year operational life). The flat discharge curve prevents performance drops in digital thermometers and blood pressure monitors. Unlike NiMH batteries, it maintains voltage in cold environments (-20°C operation certified).
How Does USB-C Charging Improve User Convenience?
The integrated Type-C port supports 5V/2A direct charging without external adapters. Smart IC detects input voltage variations from 4.5V to 5.5V, adjusting charging current to prevent overheating. A 15-minute charge provides 8 hours of flashlight use. The IP67-rated charge port resists grease accumulation common in kitchen environments.
| Charging Parameter | Specification |
|---|---|
| Input Voltage | 4.5-5.5V DC |
| Max Charging Current | 2.1A |
| 0-80% Charge Time | 105 minutes |
Advanced thermal management enables simultaneous charging and discharging without performance degradation. The bidirectional USB-C port allows using the battery as a power bank for small devices in emergencies. Charging status is indicated through a four-LED system showing 25% increments， with a dedicated red/green indicator for fault detection.
What Maintenance Practices Extend Battery Lifespan?
Store at 40-60% charge in 15-25°C environments to minimize calendar aging. Clean terminals monthly with isopropyl alcohol to maintain <0.1Ω contact resistance. Deep discharge (below 0.5V) triggers protection circuit reset – revive using dedicated 0.1C trickle charge mode. Avoid stacking more than 3 batteries vertically to prevent casing deformation.
How Does It Compare to Traditional C Cell Alternatives?
Provides 18Wh total energy vs 8.2Wh in alkaline C cells. Maintains 1.45V+ under 3A load versus alkaline’s 0.9V drop. Works in -20°C to 60°C range compared to NiMH’s -10°C limit. Costs 70% less per kWh cycle than disposable options. Passes UL2054 and IEC62133 certifications absent in most generic lithium batteries.
What Environmental Advantages Does It Offer?
500-cycle lifespan equals 1,500+ disposed alkaline batteries prevented. Contains 0% cadmium/mercury – meets EU Battery Directive 2027 standards. EVE’s closed-loop recycling recovers 92% lithium carbonate and 88% aluminum foil. Each battery reduces CO2 emissions by 14kg compared to single-use alternatives over its lifespan.
| Material | Recycling Rate | Reuse Application |
|---|---|---|
| Lithium Carbonate | 92% | New battery cathodes |
| Aluminum Foil | 88% | Battery casings |
| Copper | 95% | Electrical components |
EVE’s manufacturing process uses 40% recycled materials in new battery production. The company’s zero-liquid-discharge policy ensures 100% of process water is recycled through reverse osmosis systems. Third-party audits confirm a 68% reduction in mining-related environmental impacts compared to conventional lithium battery production.
“This battery represents a paradigm shift in primary cell replacement. The combination of lithium-polymer’s high-rate capability with USB-C charging creates a sustainable power solution for industrial applications. Our tests show 97% voltage stability after 500 rapid discharge cycles in ignition systems.”

- Q: Can it replace alkaline batteries in smoke detectors?
- A: Yes, but ensure the detector accepts 1.5V lithium. Some models require 9V.
- Q: How many charge cycles before replacement?
- A: 1,500 cycles to 80% capacity under normal use (3-5 years).
- Q: Is special charging equipment required?
- A: No – any USB-C cable/charger works. Optimal charging: 5V/2A adapter.
