Frequently Asked Questions (FAQ)
1. What is the difference between a 5000mAh and a 10000mAh 18650 battery?
A 5000mAh cell offers half the capacity of 10000mAh but is typically more compact and cost-effective. For 10000mAh, you’ll need a multi-cell pack (2 × 5000mAh cells in parallel).
2. Can I use a 5000mAh 18650 battery in my existing device?
Yes, if your device is designed for 18650 batteries. Check the voltage compatibility first – most 18650 devices accept 3.6V-3.7V.
3. What is the cycle life of a 5000mAh 18650 battery?
Under standard conditions, we guarantee 300-500 cycles to 80% capacity.
4. What certifications do you provide?
UL, CE, RoHS, UN38.3, and IEC62133. Full documentation included with every shipment.
5. How long does sample development take?
Typical sample lead time is 2-4 weeks. Mass production takes 4-6 weeks after sample approval.
6. Do you ship to Europe, North America, and Australia?
Yes. We ship globally with full UN38.3 certification.
