Frequently Asked Questions

Find answers to common questions about our batteries and services.

What is the difference between AGM and GEL batteries?

AGM (Absorbent Glass Mat) batteries use a fiberglass mat to hold the electrolyte, offering high power output and fast charging. GEL batteries use a silica additive to create a gel-like electrolyte, making them more resistant to vibration and high temperatures, ideal for deep cycle applications.

Do you offer custom battery solutions?

Yes, King Long welcomes OEM and ODM partnerships. We can customize voltage, capacity, dimensions, and labeling to meet your specific requirements.

What certifications do your batteries have?

Our products have passed ISO9001, UL (USA), CE (Europe), VDS (Germany), and domestic certifications from China's Ministry of Information Industry and National Testing Center.

What is the warranty period for your batteries?

Warranty varies by product type and usage. Typically, VRLA and AGM batteries have 1-3 years warranty, while deep cycle and GEL batteries offer 3-5 years. Please contact us for specific product warranty details.

Can your batteries be used in solar energy systems?

Absolutely. Our deep cycle, GEL, and LiFePO4 batteries are specifically designed for solar and renewable energy storage applications, offering excellent cycle life and deep discharge capabilities.
