Chisen 6-DMF-45- Comprehensive Analysis of the 12V 45Ah Lead-Acid Battery

Lead: The Chisen 6-DMF-45 is a 12V, 45Ah valve-regulated lead-acid (VRLA) battery designed for low-to-medium speed vehicles such as electric tricycles and electric motorcycles.

In the model name, "6" represents the number of cells; each cell has a nominal voltage of 2V, so 6 cells in series give a total voltage of 12V. "D" stands for Electric, "M" for Motorcycle, and "F" for acid-proof (valve-regulated sealed). "45" is the rated capacity of 45 ampere-hours (Ah), rated at the 3-hour discharge rate (C3). In other words, discharging at the 3-hour rate with a 15A current for about 3 hours reaches the rated capacity of 45Ah, providing a clear reference of driving range.

Note: Different configurations/versions of the same model may have different dimensions/weights; custom options are available on request.

The battery operates on lead-acid electrochemistry, storing and releasing energy through reversible charge/discharge reactions. The 6-DMF-45 uses thickened plates with a deep-cycle paste formula for enhanced corrosion resistance and over-discharge tolerance; the valve-regulated sealed design ensures maintenance-free operation. For the frequent start-stop and heavy climbing duty cycles of electric tricycles and motorcycles, the battery delivers good high-rate discharge and deep-discharge recovery performance.

Electric tricycles: the main power source for passenger, cargo and elderly mobility use, supporting 48V/60V/72V system configurations.

Electric motorcycles: stable power output for urban commuting and delivery needs.

Low-speed utility vehicles / campus patrol vehicles: short-distance cargo and patrol duties in factories and logistics parks.

Durable deep-cycle design: cycle life of no less than 400 cycles, suitable for frequent deep-discharge heavy-load duty.

High-rate discharge: thickened plate design delivers ample power for start-stop and climbing.

Maintenance-free: valve-regulated sealed design, no water refill needed, lower operating cost.

Wide temperature range: stable operation from -20℃ to 50℃, adaptable to various climates.

High-rate discharge: thickened plate design delivers ample power for start-stop and climbing.

Charging management: Constant-voltage charging of 2.467V per cell is recommended (approx. 14.8V for a 12V battery), with current-limited charging to avoid over/undercharging and extend service life. Use a smart charger that meets the specification and avoid overcharging or undercharging.

Routine checks: Inspect the battery appearance, terminals and connecting cables regularly, keep the surface clean, and address any swelling, leakage or loose terminals promptly.

Operating environment: Avoid prolonged operation in direct high-temperature sunlight or low-temperature conditions, ensure proper ventilation and heat dissipation, and avoid overloading to extend service life.

Electric tricycles: the main power source for passenger, cargo and elderly mobility use, supporting 48V/60V/72V system configurations.

How is the cycle life? Deep-cycle design with a cycle life of no less than 400 cycles, suited to frequent heavy-load duty.

Does it need maintenance? No. The valve-regulated sealed design is maintenance-free and requires no water refill in normal use.

What should I note about charging? Full charge voltage 2.467V per cell (approx. 14.8V for a 12V battery); use current-limited charging and avoid overcharging or undercharging.
