❓ Frequently Asked Questions
What do abbreviations like GEL, AGM, and MF mean?
GEL, AGM, Vlies, MF, Calcium/Calcium, and Hybrid are abbreviations representing different types of lead-acid battery constructions and technologies.
How do lithium battery types like LiFePO4 and Li-ion differ?
These abbreviations refer to different cathode materials used in lithium batteries. Since the materials differ, each type requires specific charging voltages for safety and efficiency.
How do I choose the correct battery charger?
Selection depends on your battery type, capacity, and intended application. Our engineers can recommend or customize the most suitable charger based on your specific requirements.
Is it possible to charge multiple batteries in parallel?
Yes, a charger can maintain several batteries connected in parallel. The charger treats them as one large battery. Ensure the combined capacity stays within the model's recommendation and use high-quality wiring to handle potential inter-battery currents.
Can I leave the charger connected permanently?
For lead-acid batteries, chargers with a maintenance (floating) mode allow you to leave them connected for short periods, though we recommend not exceeding 24 hours. For lithium batteries without a BMS system, the charger should not be left unattended.
What are the main advantages of the aluminum casing?
The aluminum casing provides a lightweight and portable design while offering excellent heat dissipation and durable protection for the internal electronics.
