Frequently Asked Questions (FAQ)

Q1: My diesel engine manufacturer recommends 950 CCA. Is 1000 CCA suitable?
A: Yes, absolutely. The 1000 CCA rating not only meets but exceeds that requirement, providing a valuable performance buffer. This extra capacity ensures stronger, faster starts, reduces strain on the starter motor, and is particularly beneficial for cold-weather operation, enhancing overall system reliability and longevity.

Q2: How does the weight of this 70Ah Na-ion battery compare to a lead-acid battery with similar CCA?
A: The difference is transformative. A lead-acid battery capable of delivering 1000 CCA would typically weigh 35-50 kg (77-110 lbs) or more. At approximately 10 kg, our Sodium-Ion battery offers a weight reduction of 70-80%, which significantly impacts fuel efficiency, payload capacity, ease of handling, and installation.

Q3: What charging system is required for this high-capacity Sodium-Ion battery?
A: It must be charged with a system specifically designed or programmable for Sodium-Ion chemistry, with an absorption voltage set to 15.6V. This applies to alternators, onboard chargers, or external chargers. Yunfan Factory can provide specifications and recommendations for compatible high-output charging solutions.

Q4: Can this battery be used in parallel for even higher capacity systems?
A: Yes, it is designed for system scalability. Batteries can be connected in parallel to increase overall Amp-hour capacity (Ah) for longer runtime. For such configurations, we strongly recommend consulting with our technical team to ensure proper cable sizing, fuse protection, and configuration best practices for balanced performance and safety.
