Deep-Cycle batteries are designed and produced against the relevant standard in JISC8702 and IEC60876-2.We design the series of batteries with much thicker plates which have very special alloys and specific pastes inside. So that extends our NPC batteries too much in deep cycle life and it can be longer 30% than NP batteries in deep cycle application.The design life is 8-year in cycle life and it can reach 3 years in service at 20oC / 68oF to 25oC / 77oF. We offer 3-year quality warranty.
Main Applications
♦Compound-power electric vehicles such as wheel chairs Electric bikes
♦Electric motorcycles
♦Electric scooters
♦Golf trolleys
Features:
♦Superior Deep Cycle Design with quite different design in plates
♦High Power Density
♦Thick Plates and High-density Active Material
♦Longer Life in Deep Cycle Applications
♦Excellent Recovery from Deep Discharge
♦The operating ambient temperature -40oC to +65oC
♦Sealed structure with reliable safety valve, no leakage and no acidic gas spillage
♦Good internal water cycling: based on the oxygen compound principle, little gas generated & little water depletion. Excellent discharge characteristics: low internal resistance, compact, excellent discharge performance.
♦Low self-discharge: making of extremely good materials, good storage life.
♦Long life: making of special alloy, cycle life 50% longer than the equivalent MP general batteries.

Koyosonic established in 1999, has been specialized in producing Lead-acid batteries, Li-ion batteries and Solar power system. As one of professional manufacturers in lead acid batteries, we have been devoted to research and development, manufacture and market to lead the users to have right batteries for their power system.
Our Lead-acid batteries include AGM batteries and Automotive batteries. AGM batteries are also called as VRLA AGM batteries, mainly including NP general batteries, NPC deep-cycle batteries, NPH High-rate batteries, NPL long-life batteries, NPF front-terminal batteries, NPM motive-power batteries, NPG/NPCG/NPMG/NPFG gel-tech batteries, NPS solar-power batteries, and OPzS & OPzV tubular batteries. For SLI batteries, we mainly have Car batteries and Motorcycle batteries. In 2009, we started to produce Li-ion batteries which mainly includes Cylindrical Cell and Polymer Cell. And we also have Li-ion Battery Pack and produce against custom design. To meet more requirement from some customers, we have built solar power system since 2012.
We have introduced advanced production and test equipments to produce lead acid batteries and so we can do much better in the battery fields as we are very strict in production management and we have first-class technology and unique directions for the batteries. We have more than 800 staff members among whom there are more than 50 professional technicians. This ensures our products are much better in performance and reliable in quality. We have gotten production license from National Quality and Technology Supervision Bureau and also we have gotten some international certificates such as UL, CE, TLC and ISO9001 & ISO14001.
In market, we mainly produced the batteries against OEM orders for some well-known international companies. Nowadays, we are going to market our own brand "Koyosonic" and welcome customers to visit us for more negotiation in our business cooperation.
