Product Description — 503048
503048 Pure Cobalt Rechargeable Lithium Polymer Battery | 3.7V 800mAh | KC Certified | Mosquito Repellent & Portable Devices | In Stock
Overview
The 503048 Standard Model Pure Cobalt Lithium Polymer Battery is a mid-capacity, certification-ready rechargeable cell engineered for reliable, long-lasting power in compact portable consumer electronics. Delivering a stable 3.7V nominal voltage and a solid 800mAh capacity in a neat 5.0 × 30 × 48mm footprint, this battery is purpose-optimized for electric mosquito repellers, portable outdoor devices, and a broad range of similarly sized handheld consumer products.
The Pure Cobalt (LiCoO₂) cathode chemistry delivers a measurably flatter discharge curve and superior charge retention compared to standard NMC or mixed-oxide alternatives — ensuring consistent device performance from a full charge through to the low-battery threshold. Holding official KC certification for the South Korean market and produced to Standard Model quality specifications, the 503048 is fully equipped for global OEM integration and direct market deployment with zero additional compliance testing required.

Key Features
- Pure Cobalt (LiCoO₂) Chemistry — Delivers a notably flatter and more stable discharge voltage profile compared to NMC or standard LiPo alternatives, ensuring that mosquito repellers and portable devices maintain consistent heating element intensity, fan speed, or electronic output from full charge through to the low-battery point — not just at the beginning of each use cycle
- 800mAh Substantial Capacity — Provides meaningful extended runtime for mosquito repellers used through full evening outdoor sessions, portable fans, handheld beauty devices, and similar moderate-drain consumer electronics that need to operate reliably for hours between charges
- KC Certified for Korean Market — Pre-qualified for direct import and retail sale in South Korea, one of Asia’s most regulated consumer electronics markets, eliminating costly and time-consuming local certification procedures for Korean OEM partners and importers
- Standard Model Reliability — Produced to consistent Standard Model specifications with controlled capacity tolerance and stable batch-to-batch cell consistency, ensuring predictable performance for device manufacturers running production lines with zero variance tolerance
- Compact 5.0mm Slim Profile — The 5.0mm thickness fits comfortably within the slim enclosures of modern mosquito repeller devices, portable outdoor gadgets, and handheld consumer electronics without requiring oversized housing designs
- Superior Charge Retention — Pure Cobalt chemistry’s inherently low self-discharge rate means mosquito repellers and seasonal outdoor devices retain meaningful charge between use sessions — ready to perform even after weeks of storage without requiring a full recharge before each outing
- Built-In Protection Circuit (PCM) — Comprehensive overcharge, over-discharge, over-current, and short-circuit protection ensures safe and reliable operation within the sealed enclosures of mosquito repellers and portable consumer devices
- Stable Performance Across Temperature Range — Operates reliably from -20°C to +60°C, covering the full spectrum of outdoor environments from cold-season camping to hot-summer outdoor dining where mosquito repellers are most heavily used
- 500+ Cycle Life — Long service lifespan reduces end-user replacement requirements and minimizes warranty return rates for device manufacturers and retail channel partners
- In-Stock Availability — No production lead time; warehoused and ready for immediate same or next business day dispatch on all standard and bulk orders
Why Pure Cobalt Chemistry Is Ideal for Mosquito Repellers
Mosquito repellers — particularly heating-element and catalytic-type devices — place a sustained, moderate constant load on their power source throughout each use session. This duty cycle specifically rewards the characteristics of Pure Cobalt chemistry:
| Device Requirement | Why Pure Cobalt Excels |
|---|---|
| Consistent heating element temperature | Flat discharge curve maintains stable voltage → stable wattage to heating element |
| Long continuous runtime | High energy density delivers more usable capacity per gram than standard LiPo |
| Seasonal storage between uses | Low self-discharge retains charge through off-season storage periods |
| Outdoor temperature variation | Wide operating range handles cold evenings and hot summer conditions equally |
| Compact device housing | High volumetric energy density maximizes capacity within slim enclosure constraints |
