F.A.Q.
Have any Question?
Are your batteries safe? What protections are in place?
Absolutely. Safety is our top priority. Our batteries are equipped with multiple built-in protection mechanisms, including overcharge protection, over-discharge protection, short-circuit protection, and temperature control. They also undergo rigorous international certification testing (such as UL, CE, and RoHS) to ensure they meet the highest safety standards.
Are your batteries recyclable? What is your environmental policy?
Yes, our batteries are 100% recyclable. We are committed to sustainability and operate a take-back program to ensure responsible end-of-life management. Please do not dispose of batteries in regular household waste. Contact us or visit our website to learn how to return your used batteries for safe recycling.
How should I properly store my batteries when not in use?
For long-term storage, we recommend charging (or discharging) the battery to approximately 50% capacity. Store it in a cool, dry place away from direct sunlight and metal objects. Ideal storage temperature is between 10°C and 25°C (50°F – 77°F). Check the charge level every 3-6 months and recharge to 50% if necessary.
Do you offer custom battery solutions for businesses or specific applications?
Absolutely. Our OEM (Original Equipment Manufacturing) division specializes in designing and producing custom battery packs to meet the unique requirements of businesses, from startups to large industries. If you need a specific voltage, capacity, form factor, or connector, please contact us.
