Frequently Asked Questions

What types of laptop battery cells do you use?

We primarily use 18650 specification cells, which are 65mm in length and 18mm in diameter. These high-quality lithium-ion cells offer excellent energy density, reliability, and safety performance.

How do I choose the right battery for my laptop?

When purchasing a replacement battery, first check the specifications of your original battery, including the model number, voltage, and capacity. Match these specifications exactly to ensure compatibility and optimal performance.

How should I charge my laptop correctly?

To maximize battery lifespan, avoid letting your battery drain completely. Charge it when it reaches 20-30%. Try to keep the charge level between 20% and 80% for daily use, and avoid exposing your laptop to extreme temperatures.

Do you offer OEM/ODM services?

Yes, SNSYIY provides comprehensive OEM and ODM services. We can customize battery designs, packaging, and branding according to your specific requirements. Contact us for more details.
