Frequently Asked Questions

Q1: What do the abbreviations MF, GEL, and AGM mean?
A: Gel, AGM, Vlies, MF, Calcium/Calcium, and Hybrid are abbreviations for different types of lead-acid batteries.
Q2: What is the difference between LiFePO4 and Li-ion abbreviations?
A: These refer to different cathode materials used in lithium batteries. Each type has specific charging voltage requirements.
Q3: How do I choose the correct battery charger?
A: Choice depends on battery type, capacity, application, and budget. Our engineers can recommend the most suitable charger based on your specific battery data.
Q4: Can I charge several batteries in parallel?
A: Yes, the charger can charge parallel-connected batteries as long as the total capacity is within the model's recommended range. High-quality wiring is required for the current between batteries.
Q5: Is it safe to leave the charger connected long-term?
A: For lead-acid batteries with maintenance mode (floating), it is safe but recommended not to exceed 24 hours. For lithium batteries without a BMS system, never leave the charger unattended.
Q6: What charging stages does this intelligent charger use?
A: It uses a 4-step process: Pre-charging, Constant Current (CC), Constant Voltage (CV), and Absorption/Float or automatic cut-off.
