Portable Power Lithium Batteries 2026 Complete Guide Manufacturer Contact Information
This professional guide is crafted by the senior R&D team of Shenzhen Kangkedi Intelligent Technology Co., Ltd., a global leading provider of new energy battery solutions with expertise in lithium battery R&D, manufacturing, and OEM/ODM customization . Portable power lithium batteries are rechargeable energy storage devices widely used in outdoor gear, emergency backup systems, and portable electronics, addressing critical pain points like short battery life, heavy weight, and safety risks of traditional battery solutions. However, many buyers and engineers lack clear understanding of their types, performance metrics, and reliable manufacturers. This guide combines global project experience to break down core definitions, key specs, compliance standards, and trusted manufacturer contacts to help you make informed decisions .

Definition & Industry Position
According to the International Electrotechnical Commission (IEC), portable power lithium batteries are rechargeable secondary batteries that utilize lithium-ion intercalation chemistry to store and deliver electrical energy, characterized by high energy density, lightweight design, and long cycle life . Put simply, they are compact, powerful energy sources that provide reliable power for on-the-go applications, solving the limitations of traditional lead-acid batteries such as heavy weight and short lifespan . As a core component in the new energy sector, these batteries play a pivotal role in enabling mobile energy solutions, with key advantages including high energy density (90–160 Wh/kg), long cycle life (≥2000 times), and intelligent safety protection via BMS systems .
Below is a comparison with traditional lead-acid batteries:
Technical Indicator | Portable Power Lithium Batteries | Lead-Acid Batteries |
|---|---|---|
Energy Density | 90–160 Wh/kg | 30–50 Wh/kg |
Cycle Life | ≥2000 times | 300–1000 times |
Weight | 60% lighter than lead-acid | Heavy |
Safety | BMS protection against overcharge/overdischarge | Risk of acid leakage |
Key Performance Metrics
Understanding core performance metrics is critical for selecting the right battery. Below are key indicators explained:
Core Indicator | Definition | Industry Reference | Selection Significance |
|---|---|---|---|
Nominal Voltage | Standard output voltage per cell | 3.2V (LiFePO4) / 3.7V (Li-ion) | Ensures compatibility with device power requirements |
Cycle Life | Charge-discharge cycles before capacity drops to 80% | ≥2000 times (LiFePO4) | Reduces long-term replacement costs |
Self-Discharge Rate | Monthly capacity loss when idle | ≤3%/month | Extends shelf life for infrequent use |
Compliance & Certifications
To ensure safety and global market access, portable power lithium batteries must meet international standards and certifications. Key standards include IEC 62133 (safety for sealed lithium batteries), while core certifications include UL (North America), FCC (North America), CE (EU), RoHS (EU), UN38.3 (global transport), and PSE (Japan) . Reputable manufacturers like Shenzhen Kangkedi Intelligent Technology Co., Ltd. hold all these certifications to guarantee product compliance .
