HQB Series

Deep Cycle AGM Batteries

We believe in that only a strong heart could provide great power, and so do batteries. As the heart of the battery, plate was paid great attention by us for the design and application of every critical point.


HQB series lead-acid batteries, positive and negative lead pastes use different density lead powder and self-developed additives. The grid is also adjusted from the traditional flat-panel design to the 3D (undulating design) design, Tin content was also increased from 1.2 per cent to 1.5 per cent. In addition,the use of a new curing process extended the curing time from 72 hours to 288 hours through strict low temperature control.

During the assembly process, we strictly control the weight and thickness of each plate, and also assembling pressure of each polar group. The batteries with gas inside are all kicked out by us, just to make sure that the consistency of each battery reaches our demanding level.


Many manufacturers improve the initial performance of batteries through high concentrations of electrolytes. During initial using, the open-circuit voltage and capacity are very good. But after a while, after-sales service will become the biggest  problem for customers. we insist on using 1.29g/cm3 low concentration electrolyte to ensure the battery life. Through 15 months of uninterrupted testing, we are willing to provide customers with 5 to 7 years of quality assurance. More details of quality assurance, please refer to our Warranty Statements.
