FAQ
Q1: What type of battery do MARSTEK products use?
A: Marstek products utilize high-quality Lithium Iron Phosphate (LiFePO₄) batteries. These batteries support over 6,000 charge-discharge cycles, with a design lifespan exceeding 10 years while retaining over 80% of their original capacity, ensuring long-term reliability.
Q2: Are Lithium Iron Phosphate batteries safe?
A: Yes, they are highly safe. Marstek employs self-developed Grade A LiFePO₄ cells with a thermal runaway threshold above 270°C, fundamentally enhancing safety. All batteries undergo rigorous tests, including nail penetration and compression, to prevent combustion or explosion during use.
Q3: Does MARSTEK offer warranty and after-sales services?
A: Absolutely. Marstek provides comprehensive support, including a 5-year worry-free after-sales service and an extended 10-year manufacturer warranty, ensuring peace of mind throughout the product lifecycle.
Q4: How do I register a MARSTEK product?
A: To streamline service, we recommend registering your product via the official Marstek mobile app after purchase for seamless activation and support.
Q5: How is shipping calculated?
A: For orders within Hong Kong totaling HKD 100 or more, shipping is free. Currently, we do not offer international shipping.
Note: Deliveries to remote areas (e.g., outlying islands) or locations requiring special handling (e.g., stair climbing) may incur additional fees. Please contact us in advance for details.
