In fact, the use of AGM batteries in deep cycle applications is short sighted because the AGM batteries will fail prematurely indeed the AGM battery capacity will start to reduce from the day of installation. With the great help of Doctor Yoshida Masayoshi in Toyama Universityin Japan,we combine gel technologies with deep cycle technologies by putting some special elements in lead alloy and some additive in electrolyte to get much more longer cycle life for NPS batteries. NPS can be regarded as another type of special gel deep-cycle batteries.Applications•Communication Systems: Switch, Microwave Stations, Mobile base Stations, Data Centers, Radio and Broadcasting Stations•Power Plants &Power Transmission Systems•Solar &Wind Power Generation System•Signal System &Emergency Lighting Systems•EPS &UPS SystemsFeatures:♦Electrolyte Uniform DistributionGel series battery is manufactured with high-quality gaseous silica to make the electrolyte in uniform distribution.♦No LeakageCurdled gaseous silica used in Gel batteries can immobilize the electrolyte and make the plates react evenly.♦Longer Cycle Service LifeDeep Cycle design (high-density active material and thick plates) &special 4BS lead paste technology prolongs the cycle service life.♦Excellent Deep Cycle AbilityUnique grid alloys &special positive/negative lead paste formulations makes the battery perform excellent in deep cycle using and recover quickly upon over discharging and extend the float service life.♦Low Self DischargeUsing high purity raw materials and gel electrolyte ensures Koyosonicbatteries have less self-discharge. ♦Environmental &Non-pollutingGas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.♦Safe &ReliableEfficient venting system automatically release excess gas when the pressure rises above the normal level &reseals the valves when it returns to the normal rate, which can protect the battery from bursting.Prodution Process:Catalogue for NPS Solar Power Battery:Company Introdution &Certifications○Koyosonic, established in 2003, has been specialized in producing Lead-acid batteries, Li-ion batteries and Solar power system.
