Battery Cell

Battery Cell Specification

The biggest advantage of prismatic cells is its thin profile, lightweight, and the effective use of space. Due to the rectangle shape of these cells, it can facilitate better layering and increase flexibility in the products. With big capacity, less cell assembled together makes monitoring on each battery cell instead of cell string become possible. Changing defective battery cell is feasible too when there is cell failure.

Precautions

Charging Parameters: Follow the manufacturer's recommended charging parameters to prevent overcharging or undercharging, which could affect battery performance and lifespan.
Operating Temperature: Maintain the battery within the specified temperature range to ensure optimal performance and safety. Extreme temperatures can impact both charging efficiency and battery life.
Depth of Discharge: Avoid deep discharges whenever possible, as frequent deep cycling can reduce the overall cycle life of the battery. Shallower discharges tend to prolong battery longevity.
Maintenance: Regularly monitor battery status, balancing, and temperature. Perform maintenance checks according to the manufacturer's guidelines to identify and address any potential issues.
Safety Precautions: Handle the battery with care, as improper handling can lead to safety hazards. Follow recommended safety practices and keep the battery away from heat sources, open flames, and water.
Parallel/Serial Connection: If connecting batteries in parallel or series, ensure proper matching and balanced charging to avoid imbalances and potential damage.
Transportation and Storage: Follow transportation regulations and proper storage guidelines to prevent damage during transit and storage periods.
Quality Assurance: Purchase batteries from reputable manufacturers and distributors to ensure product quality, performance, and safety.
Disposal and Recycling: Properly dispose of or recycle batteries according to local regulations and guidelines to minimize environmental impact.
Manufacturer Guidelines: Always refer to the manufacturer's documentation for specific recommendations on installation, usage, and maintenance.

Please note that these considerations are general guidelines. Specific instructions may vary based on the battery's manufacturer and model.
