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.

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 and confirm raw material meets high quality producing requirements, Production Quality Control (PQC) department contains The first Inspection, In-process quality control, acceptance inspection and full inspection, Outgoing Quality Control (OQC) department confirm no defective batteries come out from the factory.

AI-Powered supplier vetting

SummaryCSBattery is a China-based limited company offering solar, gel, AGM, lithium, deep-cycle, OPzV, and related battery products. It reports ISO 9001, ISO 14001, OHSAS/OHSMS 18001, and BSCI certifications. The supplier states that it provides lifetime technical and after-sales support, ODM/OEM services, broad product customization, and OEM services for popular brands. Reported production information includes 3,000,000 battery pieces annually, 50 quality-control staff, and 41–50 years of total R&D-engineer experience, although employee-count data is inconsistent across slices. It exports to numerous global regions and accepts multiple trade and payment terms. Key limitations include no 3D software design, no SDK, no overseas warehouse or showroom, no offline trade-show participation, zero stated overseas-service countries, unknown raw-material traceability, and zero reported quality-control test equipment. Financial credibility and identifiable customer cases cannot be confirmed from the provided information.

Supplier typeThe supplier is a China-based limited company located in Foshan, Guangdong, with a broad battery product portfolio and export activity across multiple global regions. It reports both agency-assisted and self-managed export capability, while also stating it has overseas agents or branches; however, the overseas-service-country count is listed as zero, creating a data inconsistency.

CertificationsThe supplier reports holding BSCI, OHSAS/OHSMS 18001, ISO 14001, and ISO 9001 certifications. These explicitly indicate coverage of social responsibility, occupational health and safety, environmental management, and quality management systems.

After-Sales capabilityThe supplier promises lifetime technical support and after-sales service, has inventory capability, accepts multiple quotation terms, and reports documented corrective-action and customer-complaint procedures with records. However, it has no overseas warehouse or showroom, and its overseas service coverage is inconsistently reported, so support may rely on remote or agent-based service.

R&D capabilityThe supplier reports new products within the past year, ODM capability, and 41–50 years of combined R&D-engineer experience. Conversely, it does not provide 3D software design services or an SDK, so the evidence supports product-development capability but not advanced digital design or platform integration.

Production capacityThe supplier reports annual output of 3,000,000 battery pieces, 50 quality-control staff, inventory capability, and lead times of within 15 working days in peak season and one month in off-season. Nevertheless, it reports zero quality-control test equipment and an unknown manufacturing-capacity contract status, which are material production-control gaps.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also offers ODM and OEM services, including OEM for popular brands. The absence of 3D software design and SDK capability limits the scope of supported design tools but does not negate the stated customization services.
