>FAQ
Q1: How to choose the right battery?
A1: Tell us your demand, then our sales will recommend a suitable
battery for you.
Q2. Do you have any MOQ limit?
A2: Yes, we have MOQ for mass production, it depends on the
different model numbers. 50-500pcs sample order is available. for
sample checking is available.
Q3. Is it OK to print my logo on the product?
A3: Yes. Please inform us formally before our production and
confirm the design firstly based on our sample.
Q4: How to solve the technical problem?
A4: To provide you with 24-hour after-sales service consultation,
make your problems easier to solve.
Q5:. What certificate your company have?
A5: ISO 9001, ISO 14001, OHSAS 18001, CE, UL, IEC 61427 test
report, Patent for gel technology and other Chinese honor.
Q6.What is your warranty time for VRLA battery ?
A6: It depends on battery capacity, depth of discharge, and battery
usage. Please kindly contact us for accurate information based on
detailed requirements.
Q7. Why battery has different capacity at different hour rate?
A7: The capacity of a battery, in Ahs, is a dynamic number that is
dependent on the discharge current. For example, a battery that is
discharged at 10A will give you more capacity than a battery that
is discharged at 100A. With the 20-hr rate, the battery is able to
deliver more Ahs than with the 2-hr rate because the 20-hr rate
uses a lower discharge current than the 2-hr rate.
Q8. Are you a battery manufacturer, and do you produce the plate by
yourself ?
A8: Yes, we are a professional battery manufacture in Fujian
Province, China. And we produce plates by ourselves.
Q9. How to proceed with an order?
A9. Firstly let us know your requirements or application. Then, We
quote according to your requirements or our suggestions.
customer confirms the samples and places a deposit for formal
order.
Finally We arrange the production.
Q10: How about the delivery time?
A10: About 7 days for stock products, around 20 days for half
container products, 30 days for 20ft full container products.
