Import 12v7h Storage Free Battery — Buy in Bulk from Supplier in China

This 12V 7Ah sealed lead-acid battery from Zhengzhou Kanglida Electronic Power Co., Ltd. is a valve-regulated, maintenance-free unit designed for standby and cyclic applications. The battery arrives fully charged from the factory and uses absorbed glass mat (AGM) technology with lead-calcium alloy plates, which keeps self-discharge low and allows up to six months of storage without a top-up charge. It is rated for 12 volts and 7 amp-hours, housed in an ABS plastic shell with a pressure-relief valve, and is spill-proof so it can be mounted in any orientation.

Kanglida states it has manufactured lead-acid batteries for over 16 years and holds CE, UL, and MSDS certifications, with test reports issued by a Chinese battery-testing authority. The company claims that nearly 70 percent of security-equipment firms in China use its batteries, though this figure should be verified directly with the supplier. Typical specifications for a 12V 7Ah VRLA battery of this class include a float-service life of three to five years at 25 degrees Celsius and an internal resistance below 20 milliohms, figures common across the industry but not explicitly confirmed in this listing.

Buyers sourcing this battery for alarm panels, emergency lighting, UPS systems, or portable medical devices should confirm the exact terminal type, dimensions, and weight with Kanglida before placing an order. The supplier states that batteries are produced fresh to order rather than pulled from shelf stock, with a typical production lead time of around 20 days including full charge and testing. Kanglida operates sales offices in Zhengzhou and Shenzhen, with the Shenzhen warehouse reportedly within one hour of Shenzhen port, which may shorten inland transit for export shipments.

Zhengzhou Kanglida Electronic Power Co., Ltd. is a Chinese manufacturer of sealed lead-acid batteries headquartered in Zhengzhou, Henan Province, with a factory in Huizhou, Guangdong Province, and sales offices in both Zhengzhou and Shenzhen. The company states it has been producing lead-acid batteries for more than 16 years and has been listed among the 100 Honest Brand Security Products Suppliers since 2010. Its product range covers 2V, 4V, 6V, and 12V batteries from 0.8Ah to 3000Ah in VRLA, AGM, gel, and deep-cycle formats.

The supplier's listing on this marketplace carries a 'harbor' trust tier and an 'imported' supplier tier, but the response rate shown is zero, meaning no response-time data is available yet. Kanglida claims CE, UL, and MSDS certifications and offers OEM services, stating it will submit intellectual-property documentation for custom orders. Buyers should request copies of the specific certification documents and test reports relevant to the 12V 7Ah model before committing to a bulk order.
