FAQ

• Q1. Are you a manufacturer or a trading company?

  A: We are a professional manufacturer with our own factory and R&D team. This allows us to ensure strict quality control, competitive pricing, and support for OEM/ODM customization for all our battery products.

• Q2. What product lines does Howell Energy offer?

  A: We provide six core product categories to meet diverse application needs: lithium polymer batteries, lithium-ion batteries, LiFePO4 (lithium iron phosphate) batteries, nickel-metal hydride (NiMH)/nickel-cadmium (NiCd) batteries, primary batteries, and custom battery packs.

• Q3. Can I order samples for quality testing?

  A: Yes, we welcome sample orders for performance and quality verification. The minimum order quantity (MOQ) for samples is 1 piece, allowing you to evaluate our products before placing bulk orders.

• Q4. What international certifications do your products hold?

  A: All our batteries comply with global standards and hold certifications including UL, CE, ROHS, UN38.3, CB/IEC62133, BIS, KC, PSE, EU and Reach. Market-specific certifications (e.g., IS16893 for India, UL for the US, KC/PSE for Korea/Japan) are available to meet regional regulatory requirements.

• Q5. Do you provide custom battery solutions?

  A: Yes, we offer one-stop customization services for all product lines. Customizable options include capacity, voltage, size, shape, connectors, communication interfaces (e.g., RS485/CAN), LCD displays, cutoff switches, and compatibility adaptations (e.g., inverter integration for energy storage packs).

• Q6. What is the warranty period for your batteries?

  A: - Standard warranty: 1-2 years for regular cells and small battery packs

  Extended warranty: Up to 5-10 years for energy storage and custom battery packs (terms vary by product type; contact our team for detailed pricing and terms)

  Warranty coverage applies to manufacturing defects, excluding damage from misuse or improper handling.

• Q7. How do you ensure product quality and safety?

  A: We implement strict quality control across the entire production process:

  ISO9001/ISO14001 certified management systems

  100% full inspection across 3 production stages, with a product pass rate of over 95%

  17+ reliability tests (high/low temperature, short circuit, overcharge/overdischarge, etc.)

  Advanced testing equipment (X-RAY inspection, capacity test cabinets, environmental chambers)

• Q8. What are the optimal storage conditions for your batteries?

  A: - Environment: Clean, dry, ventilated area with temperature 20±5℃ and humidity 45-85% RH

  State of charge (SOC): 40-80% for long-term storage; recharge every 6 months to prevent over-discharge

  Special note for primary batteries: Maximum storage life up to 10 years; passivation (if applicable) can be alleviated by low-current discharge (15-30 minutes) for storage periods exceeding 3 months.

• Q9. How do you handle defective products and after-sales support?

  A: - Defective rate: Controlled below 0.2% due to strict quality management

  After-sales response: Solutions provided within 1 week for quality issues
