Yes, our high-performance batteries can be delivered securely both by sea and by air. All products are backed by required safety test documents, including MSDS reports, authorizing safe transportation as non-hazardous cargo.
Fast charging is not recommended as a standard procedure. Frequent high-current rapid charging can accelerate thermal stress and impact the internal plate grid chemistry, potentially shortening your battery's operational lifespan.
No, partial battery replacement of lead-acid or gel battery banks is highly discouraged. Combining new batteries with aged cells creates charge imbalances and internal resistance variations, decreasing the operational efficiency of the entire battery group.
The absolute capacity of a battery (in Ah) is dynamically dependent on the speed of current discharge. Lower discharge rates (e.g., 20-Hr rate) draw less heat and distribute internal chemicals evenly, yielding significantly higher total accessible capacity compared to short-duration high-amp draws (e.g., 2-Hr rate).
Shelf life is governed directly by temperature-driven self-discharge rates. At standard ambient conditions (77°F / 25°C), the self-discharge rate stays under 3% per month. However, batteries stored without charge should be refreshed every 6 months (every 3 months under hot environments) to prevent irreversible sulfation.
Production processes utilize structural ISO 9001 systems spanning three core quality departments: Incoming Quality Control (IQC) for testing basic raw material purity; Production Quality Control (PQC) conducting continuous verification inspections; and Outgoing Quality Control (OQC) verifying perfect operational integrity prior to dispatch.
