Lead: The Chisen 6-FD-75 is a 12V, 75Ah valve-regulated lead-acid battery suitable for power or energy storage applications such as electric forklifts, low-speed utility vehicles and AGVs.

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. "F" stands for valve-regulated, "D" for Electric. "75" is the rated capacity of 75 ampere-hours (Ah), rated at the 10-hour discharge rate (C10). In other words, discharging at the 10-hour rate with a 7.5A current for about 10 hours reaches the rated capacity of 75Ah, providing a clear reference of run time for powered equipment.
Model | Dimensions L×W×H (mm) | Total Height (mm) | Weight (kg) | Terminal |
6-FD-75 | 224×163×180 | 180 | 17.00 | φ11.8-M6 |
6-FD-75 | 224×163×175 | 175 | 17.50 | φ14.0-M6 |
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 and uses flat plates with a high-density paste formula, offering high gravimetric energy density and excellent high-rate discharge performance. The valve-regulated sealed design makes it maintenance-free, while the ABS case resists vibration and impact. Together with highly conductive copper terminals, it suits frequent high-current operations such as forklifts and tow tractors.
Electric forklifts / tow tractors: stable high-current power for in-plant loading, unloading and handling operations.
Low-speed utility vehicles: reliable power for short-distance cargo transport in factories and logistics parks.
AGVs / automated guided vehicles: dependable power supporting automated logistics and production lines.
Long cycle life: per Q/321300 XP003-2023, cycle life is no less than 320 cycles.
High-rate discharge: flat plate design provides strong instantaneous discharge capability.
High gravimetric energy density: longer run time per charge.
Maintenance-free: valve-regulated sealed design, no leakage risk, low maintenance cost.
Charging management: cycle (equalizing) charging voltage of 2.40~2.45V per cell (approx. 14.4~14.7V for a 12V battery); discharge cut-off voltage 1.75V per cell. 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.
