Frequently Asked Questions
Common questions about Naradex batteries, delivery, warranty, and technical specifications
Ask Our EngineersCan your battery be delivered by sea and air?
Yes, our batteries can be delivered both by sea and by air. We have MSDS, test report for safe transport as non-dangerous products.
Can I put my logo on the battery?
Yes, you can print your logo on our batteries. OEM MOQ is from 100 pcs; custom specifications are quoted per project.
Can I fast charge my battery?
Fast charging is not recommended as is harmful for the battery.
Can I do a partial replacement of my batteries?
Partial battery replacement of lead acid battery banks is not recommended.
How about your delivery time usually?
About 7 days for stock products, around 20 days for half container products, 30 days for 20ft full container products.
What is your warranty time for VRLA battery?
It depends on battery capacity, depth of discharge, and battery usage. Please kindly contact us for accurate information based on detailed requirements.
Why battery has different capacity at different hour rate?
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.
What is the shelf life of VRLA battery and how to maintain it?
The limiting factor of battery's shelf life is the rate of self-discharge which itself is temperature dependent. VRLA batteries will self-discharge less than 3% per month at 77° F (25° C). VRLA batteries should not be stored for more than 6 months at 77° F (25° C) without recharged. If in hot temperature, recharge it every 3 month.
Are you a battery factory?
Yes, we are a professional battery factory in Guangdong Province, China.
What certificate your company have?
ISO 9001:2015 (Quality), ISO 14001:2015 (Environmental), ISO 45001:2018 (Occupational Health & Safety), CE, ROHS, and IEC 60896-21/22 / IEC 61427 test reports.
How does your factory control the quality?
We Adopt ISO 9001 quality system to control the quality. We have Incoming Quality Control (IQC) department to test raw materials, Production Quality Control (PQC) department for in-process inspection, and Outgoing Quality Control (OQC) department to confirm no defective batteries leave the factory.
