BEINING 6-CNFJ-22 Lead Crystal Battery
BEINING 6-CNFJ-22 Lead Crystal Battery
The 6-CNFJ-22 is a standard model in the German BEINING lead crystal battery series, featuring a twelve-volt design with a rated capacity of twenty-two ampere-hours. This model utilizes a unique silicon dioxide composite electrolyte technology that crystallizes reversibly during charge and discharge cycles, fundamentally solving the pain points of traditional lead-acid batteries—deep discharge vulnerability and poor low-temperature performance.
Compared to conventional AGM and gel batteries, lead crystal batteries offer higher safety, longer service life, and a wider operating temperature range, making them an ideal upgrade replacement for traditional valve-regulated lead-acid, AGM, and gel battery ranges.
Model Number Nomenclature
| Code | Meaning | Description |
|---|---|---|
| 6 | Number of series cells | Six cells of two volts in series, nominal voltage twelve volts |
| CNFJ | Battery type | Valve-regulated sealed lead crystal battery |
| 22 | Rated capacity | Twenty-two ampere-hours at twenty-hour rate |
Core Technology: Lead Crystal Electrolyte Technology
Traditional lead-acid batteries use dilute sulfuric acid as electrolyte, suffering from issues such as acid stratification, thermal runaway risk, irreversible deep discharge damage, and poor low-temperature performance. BEINING lead crystal batteries employ an innovative silicon dioxide composite electrolyte that fundamentally resolves these problems.
Working Principle: In the charged state, the electrolyte remains gel-like with excellent ionic conductivity. During discharge, the electrolyte gradually crystallizes into a stable white crystalline powder. Upon recharging, the crystals re-dissolve into gel form. The entire process is highly reversible, producing virtually no irreversible capacity loss.

Core Technical Advantages
Extremely Wide Operating Temperature Range
The minus forty degrees Celsius to plus sixty-five degrees Celsius wide-temperature adaptability allows normal operation under most extreme climate conditions. At minus forty degrees Celsius extreme cold, it still delivers approximately fifty percent of rated capacity; at plus forty degrees Celsius high temperature, it achieves a service life of seven years.
Deep Discharge Recovery
One hundred percent deep discharge is permissible—even over-discharge to zero volts can be recovered, with no significant capacity loss from daily deep cycling. This feature is decisive in areas with frequent power outages or unstable grids.
Fast Charging Capability
Charge acceptance is twice that of traditional lead-acid batteries, enabling faster recharging and significantly improving system availability.
Low Self-Discharge Rate
Extremely low self-discharge rate—under twenty degrees Celsius ambient temperature, it remains usable after two years of storage without frequent supplementary charging.
Ninety-Nine Percent Recyclable
Contains no toxic heavy metals cadmium or antimony, with a recycling rate of up to ninety-nine percent, meeting environmental protection requirements.
Safe Transport
Classified as non-hazardous goods for transport, requiring no special transport conditions.
