Frequently Asked Questions
Find answers to common questions about our services, capabilities, and processes.
How do I choose the right battery for my application?
Our battery selection depends on several factors: voltage requirements, capacity needs, size constraints, operating temperature range, cycle life expectations, and cost budget. We recommend starting with our Product Selector tool or contacting our technical team for personalized recommendations. We can typically provide recommendations within 24 hours.
What's the difference between polymer cells and cylindrical cells?
Polymer cells offer flexible form factors and can be made ultra-thin (0.4mm), making them ideal for wearables and compact devices. Cylindrical cells provide higher energy density and are better for high-power applications. Prismatic cells offer a balance between the two. Your choice depends on your specific application requirements.
What are your minimum order quantities?
MOQ varies by product type: Standard products typically have MOQ of 1,000 units. Custom solutions may have different minimums starting from 500 units. For prototyping and samples, we offer quantities as low as 10 units at sample pricing. Contact our sales team for specific MOQ details for your product.
How long does prototyping typically take?
We offer rapid prototyping with 5-7 day turnaround for most custom battery solutions. This includes design consultation, sample production, and initial testing. Rush prototyping (3-5 days) is available for an additional fee. Full production timelines depend on order volume and complexity.
Are your batteries suitable for medical applications?
Yes, we offer ISO 13485 certified medical-grade batteries with full biocompatibility testing. Our medical batteries comply with FDA regulations and include complete traceability documentation. We specialize in custom medical battery solutions for implantable devices, wearables, and diagnostic equipment.
What's the typical lifespan of your batteries?
Lifespan depends on chemistry and usage: Lithium-ion cells: 500-1000 cycles (2-3 years typical use). LiFePO4 cells: 3000-6000 cycles (8-15 years typical use). Ultra-thin polymer cells: 300-500 cycles. We provide detailed cycle life data for each product. Actual lifespan varies based on charging patterns, temperature, and discharge rates.
What are the shipping restrictions for batteries?
Lithium batteries are classified as dangerous goods and require special handling. We handle all regulatory compliance including IATA, IMDG, and DOT certifications. Shipping costs vary by destination and order size. We typically ship via air freight for urgent orders and sea freight for large volumes. Contact our logistics team for specific shipping quotes.
Do you offer international shipping?
Yes, we ship to 130+ countries worldwide. We handle all customs documentation and regulatory compliance. Typical international delivery times: Europe (5-7 days), Asia (3-5 days), Americas (7-10 days). We work with major logistics partners to ensure reliable delivery. Bulk orders may qualify for consolidated shipping discounts.
What warranty do you offer?
Standard warranty: 12 months from delivery for manufacturing defects. Extended warranty: Up to 24 months available for premium products. Medical-grade batteries: 24-month warranty with full traceability. Warranty covers defects in materials and workmanship but excludes damage from misuse or improper handling.
What should I do if I experience battery issues?
Contact our support team immediately with: Product model and serial number, Purchase date, Description of the issue, Photos if applicable. We offer troubleshooting assistance, replacement options, or full refunds within warranty period. Most issues are resolved within 48 hours. We maintain a stock of replacement units for quick turnaround.
