>Main Features1.Using oxygen recombination technology:
maintenance-free2.PbCaSn alloy for plate grids: less gassing, less
self-discharging3.High quality AGM separator: extend cycle life and
prevent micro short circuit4.ABS material: increase the strength of
battery container. (Flame-retardant ABS is optional);5.High purity
raw material: ensure low self discharge rate6.Silver-coated copper
terminals (T1, T2 terminal), brass insert terminals and lead
terminals improve the electric conductivity>Specification

acidRubberCopperFBR4V4.5Ah>Workshop SceneQ1: 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: 24 hours
after-service consultancy just for you and to make your problem to
solve easily. 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. Secondly, We quote according
to your requirements or our suggestions.Thirdly customer confirms
the samples and places a deposit for formal order. Fourthly 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./* January 22,
