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.

Are you a battery manufacturer, and do you produce the plate by yourself?

Yes, we are a professional battery manufacture in Guangdong Province, China. And we produce plates by ourselves.

What certificate your company have?

ISO 9001, ISO 14001, OHSAS 18001, CE, UL, IEC 61427 test report, Patent for gel technology and other Chinese honor.

AI-Powered supplier vetting

SummaryCSPOWER is a limited company with stated export activity across numerous countries, valid import/export licensing, and substantial battery production information. It reports ISO9001, ISO14001, and OHSAS18001 certifications, although supplier-management-system certification is separately listed as NIL. The supplier demonstrates strong customization and 3D design capabilities, with new products reported in the past year. Production-related evidence includes 2,000,000 battery pieces annually and 41–50 quality-control staff, but the records contain conflicting workforce and output information. Service strengths include participation in an overseas trade show, multiple quotation terms, and one-month lead times in both peak and off-season. However, no overseas agents, branches, warehouses, showrooms, or in-stock capability are reported; quality assurance, traceability, complaint handling, and corrective-action status remain unclear or categorized as “Others.”

Supplier typeThe supplier is identified as a limited company and is not part of a larger company group. It also holds a valid import/export license, supporting its ability to operate as an independent exporting supplier.

CertificationsThe company states that it holds ISO9001, ISO14001, and OHSAS18001 certifications, but supplier-management-system certification is listed as NIL. Quality-assurance and traceability statuses are also recorded as unknown, so certification evidence is positive but not fully consistent across the records.

R&D capabilityThe supplier reports new products within the past year, 3D software design services, and continuous innovation supported by a professional quality management system. These statements provide explicit evidence of ongoing product-development capability.

Production capacityProduction evidence includes 2,000,000 battery pieces annually, 41–50 quality-control staff, and one-month average lead times in both peak and off-season. However, the supplier reports no in-stock capability, while outsourcing procedures and manufacturing-capacity contracts are unknown.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, flexible customization, and 3D software design services. This indicates broad customization coverage for customer-specific requirements.

Client casesThe supplier states that it has exported to numerous countries, including the USA, Brazil, Italy, Germany, Spain, Russia, Korea, Thailand, South Africa, and Nigeria, and reports that 71%–90% of sales are exports. It also participated in Solartech Indonesia 2024, although named customer references or project case details are not provided.
