How does your factory control quality?

We adopt the ISO 9001 quality system. We have Incoming Quality Control (IQC), Production Quality Control (PQC), and Outgoing Quality Control (OQC) departments to ensure no defective batteries leave the factory.

Is the capacity based on 10HR or 20HR?

For 4AH to 17AH batteries, it is 20HR. For 24AH to 250AH batteries, it is 10HR.

Why does battery capacity vary at different hour rates?

Battery capacity in Ahs is dynamic and dependent on discharge current. Lower discharge currents (like the 20-hr rate) allow the battery to deliver more Ahs than higher currents (like the 2-hr rate).

What is the warranty time for VRLA batteries?

It depends on battery capacity, depth of discharge, and usage. Please contact us for accurate information based on detailed requirements.

Can I fast charge my battery?

Fast charging is not recommended as it 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 do you solve battery damage problems?

If a problem occurs, we gather pictures and analyze the usage condition to find the cause. If it is a production problem, we will replace the new one in the next shipment.

AI-Powered supplier vetting

SummaryAMAXPOWER demonstrates broad manufacturing, R&D, customization, and certification capabilities. It provides 3D design, ODM/OEM, SDK, and multiple customization options, supported by four R&D engineers and available development documentation. The supplier reports ISO9001, ISO14001, ISO45001, OHSAS18001, SA8000, CE, and TLC-related certifications or audits. Production evidence includes a 50,000-square-meter facility and stated annual capacity of approximately 2,000,000 kVAh. Service strengths include inventory capability, participation in an offline trade show, and proximity to Shenzhen and Guangzhou ports. However, it lacks overseas warehouses, showrooms, agents, and branches; service lead times extend to one month in peak season. After-sales and quality-control governance is weakly documented: no written corrective-action or complaint-handling procedures are reported, quality assurance and traceability status are unknown, and testing equipment quantity is stated as zero. Financial information is present...

Supplier typeThe supplier is presented as a large-scale battery manufacturer operating from a 50,000-square-meter industrial park in Guangdong, China, with stated annual production capacity of approximately 2,000,000 kVAh. This supports classification as a manufacturing supplier rather than only a trading or service company.

CertificationsThe supplier states that it has passed ISO9001 and ISO14001 certification, obtained ISO45001 certification, passed OHSAS18001 and SA8000 audits, and has products with certifications including CE and TLC. These stated certifications and audits provide explicit evidence of formal quality, environmental, occupational safety, and social responsibility systems.

R&D capabilityThe supplier reports new products during the past year, four R&D engineers, available R&D audit documentation, ODM and OEM capability, and an available SDK. Its engineers handle customer-request confirmation, technical support, and new product development, providing explicit evidence of active product-development capability.

Production capacityProduction capability is supported by a 50,000-square-meter industrial park, stated annual capacity of approximately 2,000,000 kVAh, inventory capability, and ten qualified service-capability suppliers. Nevertheless, the supplier reports zero quality-control test equipment and unknown quality-assurance and traceability status, so production scale is evidenced but production-control robustness is not fully demonstrated.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides 3D software design, ODM, OEM for popular brands, and SDK support, indicating broad customization and design-integration capability.
