Frequently Asked Questions

Are you a professional battery manufacturer?
Yes, we have over 17 years of experience in the battery manufacturing industry, specializing in high-quality plates and VRLA batteries.
What is the typical delivery time for orders?
Stock products typically ship within 7 days. For full 20ft containers, the production time is approximately 30 days.
How do you ensure the quality of your batteries?
We utilize the ISO 9001 quality system, including IQC for raw materials, PQC for in-process monitoring, and OQC for a final full inspection before shipment.
What is the difference between 10HR and 20HR capacity ratings?
Batteries from 4AH to 17AH are usually rated at 20HR, while larger batteries from 24AH to 250AH are rated at the 10HR standard.
What is the shelf life of a VRLA battery?
VRLA batteries self-discharge less than 3% per month at 25°C. We recommend recharging every 6 months if stored at room temperature, or every 3 months in hotter climates.
Can I perform a partial replacement of a battery bank?
Partial replacement of lead-acid battery banks is not recommended, as it can lead to imbalances and reduced service life for the new units.
